-Installing libssh2
-==================
-
- * Untar this tarball (which, if you're reading this, you've already done)
-
- * Run: ./configure (passing additional options as desired)
-
-	In addition the the standard set of ./configure options (e.g. --prefix)
-	there are five switches which you may wish to pay attention to:
-
-	* --with-openssl=[DIR]
-
-		libssh2 requires the OpenSSL library (http://www.openssl.org) for
-		cipher and hash method implementations.
-
-		./configure will attempt to locate OpenSSL in a number of default locations:
-			/usr/local/ssl /usr/local /usr /usr/local/openssl
-		If your installation of OpenSSL is in another location, specify it here.
-
-	* --with-zlib=[DIR]
-
-		If present, libssh2 will attempt to use the zlib (http://www.zlib.org)
-		for payload compression, however zlib is not required.
-
-		./configure will attempt to location a zlib installation in a number of default locations:
-			/usr/local /usr /usr/local/libz /usr/libz /usr/local/zlib /usr/zlib
-		If your installation of zlib is in another location, you may specify it here.
-
-	* --enable-crypt-none
-
-		The SSH2 Transport allows for unencrypted data transmission using the "none" cipher.
-		Because this is such a huge security hole, it is typically disabled on
-		SSH2 implementations and is diabled in libssh2 by default as well.
-
-		Enabling this option will allow for "none" as a negotiable method,
-		however it still requires that the method be advertized by the remote end
-		and that no more-prefferable methods are available.
-
-	* --enable-mac-none
-
-		The SSH2 Transport also allows implementations to forego a message authentication code.
-		While this is less of a security risk than using a "none" cipher, it is still not
-		recommended as disabling MAC hashes removes a layer of security.
-
-		Enabling this option will allow for "none" as a negotiable method,
-		however it still requires that the method be advertized by the remote end
-		and that no more-prefferable methods are available.
-
-	* --disable-gex-new
-
-		The diffie-hellman-group-exchange-sha1 (dh-gex) key exchange method originally defined
-		an exchange negotiation using packet type 30 to request a generation pair based
-		on a single target value.  Later refinement of dh-gex provided for range and target
-		values.  By default libssh2 will use the newer range method.
-
-		If you experience trouble connecting to an old SSH server using dh-gex,
-		try this option to fallback on the older more reliable method.
-
- * Run: make all install

 libssh2 - SSH2 library
 ======================
 
-Version 0.7
------------
+libssh2 is a library implementing the SSH2 protocol, available under
+the revised BSD license.
 
-  Added libssh2_userauth_hostbased_fromfile_ex() for authenticating from hostkey.
+Web site: http://www.libssh2.org/
 
-  Added configure recognition for MacOSX (Darwin) (Thanks Gabe)
+Mailing list: http://cool.haxx.se/mailman/listinfo/libssh2-devel
 
-  Fixed extended data identification in libssh2_channel_read().
+License: see COPYING
 
-  Fixed window adjust code.  Hadn't acknowledged adjustments correctly.
+Source code: https://github.com/libssh2/libssh2
 
-  Removed initial_window_size requirement for sending window adjust packet.
+Web site source code: https://github.com/libssh2/www
 
-
-Version 0.6
------------
-
-  Added LIBSSH2_FLAG_SIGPIPE to enable/disable SIGPIPE generated by send()/recv() calls. Default off.
-
-  Added libssh2_session_flag() to set optional session flags.
-
-  Collapsed exchanging_keys/newkeys/authenticated flags into single state attribute.
-
-  Fix zlib compression issue when internal buffer state misses partial sync.
-
-  Fix segfault when libssh2_session_methods() is called prior to session_startup().
-
-  Fixed client to server channel windowing.  Pervent send queue overruns.
-
-  Swapped banner send/receive order (send first, then wait for response).
-
-Version 0.5
------------
-
-  *** BC Break ***
-  Reimplemented libssh2_session_methods() to match libssh2_session_method_pref() style
-
-  Fixed libssh2_attr2bin() (effects any setstat style call).
-
-  Fixed authenticating with encrypted private key.
-
-  Fixed authenticating via ssh-dss public key.
-
-  Fixed KEX_INIT cookie and packet padding to use actual random data
-
-  Added DESTDIR support to makefiles (Adam Go³êbiowski -- I hope that character set translates right)
-
-  Added libssh2_channel_forward_listen_ex(), libssh2_channel_forward_cancel(), and libssh2_channel_forward_accept().
-
-  Added ./configure option '--disable-gex-new' to allow using the older group-exchange format
-
-  Added MAC methods hmac-md5 and hmac-md5-96.
-
-Version 0.4
------------
-
-  Fixed crash when trying to free sftp_dirhandle data from a filehandle struct.
-
-  Fixed leak in sftp_open_ex(), handle->handle not freed in handle_close().
-
-  Fixed leak in sftp_symlink_ex(), result for READLINK and REALPATH not freed unless there was an error.
-
-  Added libssh2_banner_set(), specify an arbitrary banner to send on introduction.
-
-Version 0.3
------------
-
-  Fixed libssh2_channel_read_ex().  Packet loop initialized BEFORE transport polled for new packets (should have been after).
-
-  Fixed blocking issues in scp_send()/scp_recv().
-
-  Fixed degree of indirection in macerror callback.
-
-  Changed packet read mechanism to use a fixed buffer and avoid unnecessary alloc/free calls. (especially while non-block looping)
-
-  Added channel close callback.
-
-  Added SFTP support (Using its own header file: libssh2_sftp.h)
-
-Version 0.2
------------
-
-  Changed extended data ignorance mechanism:
-    libssh2_channel_ignore_extended_data() changed to libssh2_channel_handle_extended_data()
-    Macro introduced for backward compatability during beta phase.
-    *** THE LIBSSH2_CHANNEL_IGNORE_EXTENDED_DATA() MACRO WILL BE REMOVED PRIOR TO 1.0 RELEASE ***
-    libssh2_channel_handle_extended_data() may be passed one of three "ignore_mode" constants
-      LIBSSH2_CHANNEL_EXTENDED_DATA_NONE       Default behavior, queue ED packets and return them with read_ex
-      LIBSSH2_CHANNEL_EXTENDED_DATA_IGNORE     Equivalent to libssh2_channel_ignore_extended_data()
-                                               IGNORE will implicitly flush the extended data stream(s)
-      LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE      Calls to channel_read() will check both the standard data stream
-                                               and the extended data stream(s) for the first available packet
-
-  Changed libssh2_session_disconnect_ex() to return an error code when alloc fails
-
-  Added libssh2_channel_flush_ex() and basic macros: ..._flush() ..._flush_stderr()
-    flush_ex accepts either the streamid (0 for standard data, 1 for stderr) or one of the two following constants:
-      LIBSSH2_CHANNEL_FLUSH_ALL                Flush all streams
-      LIBSSH2_CHANNEL_FLUSH_EXTENDED_DATA      Flush all streams EXCEPT the standard data stream
-
-  Added libssh2_session_callback_set() for setting ignore/debug/disconnect/macerror callbacks
-
-  Added libssh2_session_method_pref() to selectively set methods and method preferences.
-
-  Added libssh2_session_methods() to determine what methods were negotiated.
-
-  Added libssh2_session_abstract() for retreiving &session->abstract
-
-  Added libssh2_session_last_error() for retreiving error codes/messages
-
-Version 0.1
------------
-
-  Initial Release:
-    KEX methods: diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1

+	Definitions needed to implement a specific crypto library
+
+This document offers some hints about implementing a new crypto library
+interface.
+
+A crypto library interface consists of at least a header file, defining
+entities referenced from the libssh2 core modules.
+Real code implementation (if needed), is left at the implementor's choice.
+
+This document lists the entities that must/may be defined in the header file.
+
+Procedures listed as "void" may indeed have a result type: the void indication
+indicates the libssh2 core modules never use the function result.
+
+
+1) Crypto library initialization/termination.
+
+void libssh2_crypto_init(void);
+Initializes the crypto library. May be an empty macro if not needed.
+
+void libssh2_crypto_exit(void);
+Terminates the crypto library use. May be an empty macro if not needed.
+
+
+2) HMAC
+
+libssh2_hmac_ctx
+Type of an HMAC computation context. Generally a struct.
+Used for all hash algorithms.
+
+void libssh2_hmac_ctx_init(libssh2_hmac_ctx ctx);
+Initializes the HMAC computation context ctx.
+Called before setting-up the hash algorithm.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_update(libssh2_hmac_ctx ctx,
+	                 const unsigned char *data,
+	                 int datalen);
+Continue computation of an HMAC on datalen bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_final(libssh2_hmac_ctx ctx,
+	                unsigned char output[]);
+Get the computed HMAC from context ctx into the output buffer. The
+minimum data buffer size depends on the HMAC hash algorithm.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_cleanup(libssh2_hmac_ctx *ctx);
+Releases the HMAC computation context at ctx.
+
+
+3) Hash algorithms.
+
+3.1) SHA-1
+Must always be implemented.
+
+SHA_DIGEST_LENGTH
+#define to 20, the SHA-1 digest length.
+
+libssh2_sha1_ctx
+Type of an SHA1 computation context. Generally a struct.
+
+int libssh2_sha1_init(libssh2_sha1_ctx *x);
+Initializes the SHA-1 computation context at x.
+Returns 1 for success and 0 for failure
+
+void libssh2_sha1_update(libssh2_sha1_ctx ctx,
+	                 const unsigned char *data,
+	                 size_t len);
+Continue computation of SHA-1 on len bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_sha1_final(libssh2_sha1_ctx ctx,
+                        unsigned char output[SHA1_DIGEST_LEN]);
+Get the computed SHA-1 signature from context ctx and store it into the
+output buffer.
+Release the context.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_sha1_init(libssh2_hmac_ctx *ctx,
+	                    const void *key,
+	                    int keylen);
+Setup the HMAC computation context ctx for an HMAC-SHA-1 computation using the
+keylen-byte key. Is invoked just after libssh2_hmac_ctx_init().
+
+3.2) SHA-256
+Must always be implemented.
+
+SHA256_DIGEST_LENGTH
+#define to 32, the SHA-256 digest length.
+
+libssh2_sha256_ctx
+Type of an SHA-256 computation context. Generally a struct.
+
+int libssh2_sha256_init(libssh2_sha256_ctx *x);
+Initializes the SHA-256 computation context at x.
+Returns 1 for success and 0 for failure
+
+void libssh2_sha256_update(libssh2_sha256_ctx ctx,
+	                   const unsigned char *data,
+	                   size_t len);
+Continue computation of SHA-256 on len bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_sha256_final(libssh2_sha256_ctx ctx,
+	                  unsigned char output[SHA256_DIGEST_LENGTH]);
+Gets the computed SHA-256 signature from context ctx into the output buffer.
+Release the context.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+int libssh2_sha256(const unsigned char *message,
+                   unsigned long len,
+                   unsigned char output[SHA256_DIGEST_LENGTH]);
+Computes the SHA-256 signature over the given message of length len and
+store the result into the output buffer.
+Return 1 if error, else 0.
+Note: Seems unused in current code, but defined in each crypto library backend.
+

+#define as 1 if the crypto library supports HMAC-SHA-256, else 0.
+If defined as 0, the rest of this section can be omitted.

+Installation Instructions

+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
+Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here

+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).  Here is a another example:
+
+     /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.
+
+More configure options
+======================
+
+Some ./configure options deserve additional comments:
+
+ * --enable-crypt-none
+
+	The SSH2 Transport allows for unencrypted data
+	transmission using the "none" cipher.  Because this is
+	such a huge security hole, it is typically disabled on
+	SSH2 implementations and is disabled in libssh2 by
+	default as well.
+
+	Enabling this option will allow for "none" as a
+	negotiable method, however it still requires that the
+	method be advertized by the remote end and that no
+	more-preferable methods are available.
+
+ * --enable-mac-none
+
+	The SSH2 Transport also allows implementations to
+	forego a message authentication code.  While this is
+	less of a security risk than using a "none" cipher, it
+	is still not recommended as disabling MAC hashes
+	removes a layer of security.
+
+	Enabling this option will allow for "none" as a
+	negotiable method, however it still requires that the
+	method be advertized by the remote end and that no
+	more-preferable methods are available.
+
+ * --disable-gex-new
+
+	The diffie-hellman-group-exchange-sha1 (dh-gex) key
+	exchange method originally defined an exchange
+	negotiation using packet type 30 to request a
+	generation pair based on a single target value.  Later
+	refinement of dh-gex provided for range and target
+	values.  By default libssh2 will use the newer range
+	method.
+
+	If you experience trouble connecting to an old SSH
+	server using dh-gex, try this option to fallback on
+	the older more reliable method.
+
+ * --with-libgcrypt
+ * --without-libgcrypt
+ * --with-libgcrypt-prefix=DIR
+
+	libssh2 can use the Libgcrypt library
+	(http://www.gnupg.org/) for cryptographic operations.
+	Either Libgcrypt or OpenSSL is required.
+
+	Configure will attempt to locate Libgcrypt
+	automatically.
+
+	If your installation of Libgcrypt is in another
+	location, specify it using --with-libgcrypt-prefix.
+
+ * --with-openssl
+ * --without-openssl
+ * --with-libssl-prefix=[DIR]
+
+	libssh2 can use the OpenSSL library
+	(http://www.openssl.org) for cryptographic operations.
+	Either Libgcrypt or OpenSSL is required.
+
+	Configure will attempt to locate OpenSSL in the
+	default location.
+
+	If your installation of OpenSSL is in another
+	location, specify it using --with-libssl-prefix.
+
+ * --with-libz
+ * --without-libz
+ * --with-libz-prefix=[DIR]
+
+	If present, libssh2 will attempt to use the zlib
+	(http://www.zlib.org) for payload compression, however
+	zlib is not required.
+
+	If your installation of Libz is in another location,
+	specify it using --with-libz-prefix.
+
+ * --enable-debug
+
+	Will make the build use more pedantic and strict compiler
+	options as well as enable the libssh2_trace() function (for
+	showing debug traces).

+
+Installation instructions are in docs/INSTALL
+=======
+To build libssh2 you will need CMake v2.8 or later [1] and one of the
+following cryptography libraries:
+
+* OpenSSL
+* Libgcrypt
+* WinCNG
+
+Getting started
+---------------
+
+If you are happy with the default options, make a new build directory,
+change to it, configure the build environment and build the project:
+
+  mkdir bin
+  cd bin
+  cmake ..
+  cmake --build .
+
+libssh2 will be built as a static library and will use any
+cryptography library available.  The library binary will be put in
+`bin/src`, with the examples in `bin/example` and the tests in
+`bin/tests`.
+
+Customising the build
+---------------------
+
+Of course, you might want to customise the build options.  You can
+pass the options to CMake on the command line:
+
+  cmake -D<option>=<value> ..
+
+The following options are available:
+
+ * `BUILD_SHARED_LIBS=OFF`
+
+    Determines whether libssh2 is built as a static library or as a
+    shared library (.dll/.so).  Can be `ON` or `OFF`.
+
+ * `CRYPTO_BACKEND=`
+
+    Chooses a specific cryptography library to use for cryptographic
+    operations.  Can be `OpenSSL` (http://www.openssl.org),
+    `Libgcrypt` (http://www.gnupg.org/), `WinCNG` (Windows Vista+) or
+    blank to use any library available.
+
+    CMake will attempt to locate the libraries automatically.  See [2]
+    for more information.
+
+ * `ENABLE_ZLIB_COMPRESSION=OFF`
+
+    Will use zlib (http://www.zlib.org) for payload compression.  Can
+    be `ON` or `OFF`.
+
+ * `ENABLE_CRYPT_NONE=OFF`
+
+    The SSH2 Transport allows for unencrypted data transmission using
+    the "none" cipher.  Because this is such a huge security hole, it
+    is typically disabled on SSH2 implementations and is disabled in
+    libssh2 by default as well.
+
+    Enabling this option will allow for "none" as a negotiable method,
+    however it still requires that the method be advertized by the
+    remote end and that no more-preferable methods are available.
+
+ * `ENABLE_MAC_NONE=OFF`
+
+    The SSH2 Transport also allows implementations to forego a message
+    authentication code.  While this is less of a security risk than
+    using a "none" cipher, it is still not recommended as disabling
+    MAC hashes removes a layer of security.
+
+    Enabling this option will allow for "none" as a negotiable method,
+    however it still requires that the method be advertized by the
+    remote end and that no more-preferable methods are available.
+
+ * `ENABLE_GEX_NEW=ON`
+
+    The diffie-hellman-group-exchange-sha1 (dh-gex) key exchange
+    method originally defined an exchange negotiation using packet
+    type 30 to request a generation pair based on a single target
+    value.  Later refinement of dh-gex provided for range and target
+    values.  By default libssh2 will use the newer range method.
+
+    If you experience trouble connecting to an old SSH server using
+    dh-gex, try this option to fallback on the older more reliable
+    method.
+
+ * `ENABLE_DEBUG_LOGGING=ON` in Debug, `=OFF` in Release
+
+    Will enable the libssh2_trace() function for showing debug traces.
+
+Build tools
+-----------
+
+The previous examples used CMake to start the build using:
+
+  cmake --build .
+
+Alternatively, once CMake has configured your project, you can just
+use your own build tool, e.g GNU make, Visual Studio, etc., from that
+point onwards.
+
+Tests
+-----
+
+To test the build, run the appropriate test target for your build
+system.  For example:
+
+  cmake --build . --target test
+or
+  cmake --build . --target RUN_TESTS
+
+How do I use libssh2 in my project if my project doesn't use CMake?
+-------------------------------------------------------------------
+
+If you are not using CMake for your own project, install libssh2
+
+  cmake <libssh2 source location>
+  cmake --build .
+  cmake --build . --target install
+or
+  cmake --build . --target INSTALL
+
+and then specify the install location to your project in the normal
+way for your build environment.  If you don't like the default install
+location, add `-DCMAKE_INSTALL_PREFIX=<chosen prefix>` when initially
+configuring the project.
+
+How can I use libssh2 in my project if it also uses CMake?
+----------------------------------------------------------
+
+If your own project also uses CMake, you don't need to worry about
+setting it up with libssh2's location.  Just add just the following
+lines and CMake will find libssh2 on your system, set up the necessary
+paths and link the library with your binary.
+
+    find_package(Libssh2 REQUIRED CONFIG)
+    target_link_libraries(my_project_target Libssh2::libssh2)
+
+Of course, you still have to make libssh2 available on your system
+first.  You can install it in the traditional way shown above, but you
+don't have to.  Instead you can just build it, which will export its
+location to the user package registry [3] where `find_package` will
+find it.
+
+You can even combine the two steps using a so-called 'superbuild'
+project [4] that downloads, builds and exports libssh2, and then
+builds your project:
+
+    include(ExternalProject)
+
+    ExternalProject_Add(
+        Libssh2
+        URL <libssh2 download location>
+        URL_HASH SHA1=<libssh2 archive SHA1>
+	INSTALL_COMMAND "")
+
+    ExternalProject_Add(
+        MyProject DEPENDS Libssh2
+        SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/src
+        INSTALL_COMMAND "")

+Things TODO
+===========
+
+* Fix the numerous malloc+copy operations for sending data, see "Buffering
+  Improvements" below for details
+
+* make sure the windowing code adapts better to slow situations so that it
+  doesn't then use as much memory as today. Possibly by an app-controllable
+  "Window mode"?
+
+* Decrease the number of mallocs. Everywhere. Will get easier once the
+  buffering improvements have been done.
+
+* Use SO_NOSIGPIPE for Mac OS/BSD systems where MSG_NOSIGNAL doesn't
+  exist/work
+
+* Extend the test suite to actually test lots of aspects of libssh2
+
+* Fix all compiler warnings (some can't be done without API changes)
+
+* Expose error messages sent by the server
+
+* select() is troublesome with libssh2 when using multiple channels over
+  the same session. See "New Transport API" below for more details.
+
+At next SONAME bump
+===================
+
+* stop using #defined macros as part of the official API. The macros should
+  either be turned into real functions or discarded from the API.
+
+* fix the parts of the API where object pointers and function pointers are
+  mixed like libssh2_session_callback_set()
+
+* remove the following functions from the API/ABI
+
+  libssh2_base64_decode()
+  libssh2_session_flag()
+  libssh2_channel_handle_extended_data()
+  libssh2_channel_receive_window_adjust()
+  libssh2_poll()
+  libssh2_poll_channel_read()
+  libssh2_session_startup() (libssh2_session_handshake() is the replacement)
+  libssh2_banner_set() (libssh2_session_banner_set() is the repacement)
+
+* Rename a few function:
+
+  libssh2_hostkey_hash => libssh2_session_hostkey_hash
+  libssh2_banner_set => libssh2_session_banner_set
+
+* change 'int' to 'libssh2_socket_t' in the public API for sockets.
+
+* Use 'size_t' for string lengths in all functions.
+
+* Add a comment field to struct libssh2_knownhost.
+
+* remove the existing libssh2_knownhost_add() function and rename
+  libssh2_knownhost_addc to become the new libssh2_knownhost_add instead
+
+* remove the existing libssh2_scp_send_ex() function and rename
+  libssh2_scp_send64 to become the new libssh2_scp_send instead.
+
+* remove the existing libssh2_knownhost_check() functin and rename

+
+Buffering Improvements
+======================
+
+transport_write
+
+  - If this function gets called with a total packet size that is larger than
+  32K, it should create more than one SSH packet so that it keeps the largest
+  one below 32K
+
+sftp_write
+
+  - should not copy/allocate anything for the data, only create a header chunk
+  and pass on the payload data to channel_write "pointed to"
+
+New Transport API
+=================
+
+THE PROBLEM
+
+The problem in a nutshell is that when an application opens up multiple
+channels over a single session, those are all using the same socket. If the
+application is then using select() to wait for traffic (like any sensible app
+does) and wants to act on the data when select() tells there is something to
+for example read, what does an application do?
+
+With our current API, you have to loop over all the channels and read from
+them to see if they have data. This effectively makes blocking reads
+impossible. If the app has many channels in a setup like this, it even becomes
+slow. (The original API had the libssh2_poll_channel_read() and libssh2_poll()
+to somewhat overcome this hurdle, but they too have pretty much the same
+problems plus a few others.)
+
+Traffic in the other direction is similarly limited: the app has to try
+sending to all channels, even though some of them may very well not accept any
+data at that point.
+
+A SOLUTION
+
+I suggest we introduce two new helper functions:
+
+ libssh2_transport_read()
+
+ - Read "a bunch" of data from the given socket and returns information to the
+   app about what channels that are now readable (ie they will not block when
+   read from). The function can be called over and over and it will repeatedly
+   return info about what channels that are readable at that moment.
+
+ libssh2_transport_write()
+
+ - Returns information about what channels that are writable, in the sense
+   that they have windows set from the remote side that allows data to get
+   sent. Writing to one of those channels will not block. Of course, the
+   underlying socket may only accept a certain amount of data, so at the first
+   short return, nothing more should be attempted to get sent until select()
+   (or equivalent) has been used on the master socket again.
+
+I haven't yet figured out a sensible API for how these functions should return
+that info, but if we agree on the general principles I guess we can work that
+out.
+
+VOLUNTARY
+
+  I wanted to mention that these two helper functions would not be mandatory
+  in any way. They would just be there for those who want them, and existing
+  programs can remain using the old functions only if they prefer to.
+
+New SFTP API
+============
+
+PURPOSE
+
+ Provide API functions that explicitly tells at once that a (full) SFTP file
+ transfer is wanted, to allow libssh2 to leverage on that knowledge to speed
+ up things internally. It can for example do read ahead, buffer writes (merge
+ small writes into larger chunks), better tune the SSH window and more. This
+ sort of API is already provided for SCP transfers.
+
+API
+
+ New functions:
+
+    LIBSSH2_SFTP_HANDLE *libssh2_sftp_send(SFTP_SESSION *sftp,
+                                           uint64_t filesize,
+                                           char *remote_path,
+                                           size_t remote_path_len,
+                                           long mode);
+
+ Tell libssh2 that a local file with a given size is about to get sent to
+ the SFTP server.
+
+    LIBSSH2_SFTP_HANDLE *libssh2_sftp_recv();
+
+ Tell libssh2 that a remote file is requested to get downloaded from the SFTP
+ server.
+
+ Only the setup of the file transfer is different from an application's point
+ of view. Depending on direction of the transfer(s), the following already
+ existing functions should then be used until the transfer is complete:
+
+ libssh2_sftp_read()
+ libssh2_sftp_write()
+
+HOW TO USE
+
+ 1. Setup the transfer using one of the two new functions.
+
+ 2. Loop through the reading or writing of data.
+
+ 3. Cleanup the transfer

+Write data to a channel stream. All channel streams have one standard I/O
