The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, fully featured, and Open Source toolkit implementing the
Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1)
protocols as well as a full-strength general purpose cryptography library.
The project is managed by a worldwide community of volunteers that use the
Internet to communicate, plan, and develop the OpenSSL toolkit and its
related documentation.
Secure Sockets Layer (SSLv3) and Transport Layer Security (TLS) protocols as
well as a full-strength general purpose cryptograpic library. The project is
managed by a worldwide community of volunteers that use the Internet to
communicate, plan, and develop the OpenSSL toolkit and its related
documentation.
OpenSSL is based on the excellent SSLeay library developed from Eric A. Young
OpenSSL is descended from the SSLeay library developed by Eric A. Young
and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
OpenSSL license plus the SSLeay license) situation, which basically means
that you are free to get and use it for commercial and non-commercial
purposes as long as you fulfill the conditions of both licenses.

OVERVIEW
--------
@ -28,90 +28,39 @@
The OpenSSL toolkit includes:
libssl.a:
Implementation of SSLv2, SSLv3, TLSv1 and the required code to support
both SSLv2, SSLv3 and TLSv1 in the one server and client.
Provides the client and server-side implementations for SSLv3 and TLS.
libcrypto.a:
General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not
actually logically part of it. It includes routines for the following:
Ciphers
libdes - EAY's libdes DES encryption package which was floating
around the net for a few years, and was then relicensed by
him as part of SSLeay. It includes 15 'modes/variations'
of DES (1, 2 and 3 key versions of ecb, cbc, cfb and ofb;
pcbc and a more general form of cfb and ofb) including desx
in cbc mode, a fast crypt(3), and routines to read
passwords from the keyboard.
RC4 encryption,
RC2 encryption - 4 different modes, ecb, cbc, cfb and ofb.
Blowfish encryption - 4 different modes, ecb, cbc, cfb and ofb.
IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb.
Digests
MD5 and MD2 message digest algorithms, fast implementations,
SHA (SHA-0) and SHA-1 message digest algorithms,
MDC2 message digest. A DES based hash that is popular on smart cards.
Public Key
RSA encryption/decryption/generation.
There is no limit on the number of bits.
DSA encryption/decryption/generation.
There is no limit on the number of bits.
Diffie-Hellman key-exchange/key generation.
There is no limit on the number of bits.
X.509v3 certificates
X509 encoding/decoding into/from binary ASN1 and a PEM
based ASCII-binary encoding which supports encryption with a
private key. Program to generate RSA and DSA certificate
requests and to generate RSA and DSA certificates.
Systems
The normal digital envelope routines and base64 encoding. Higher
level access to ciphers and digests by name. New ciphers can be
loaded at run time. The BIO io system which is a simple non-blocking
IO abstraction. Current methods supported are file descriptors,
sockets, socket accept, socket connect, memory buffer, buffering, SSL
client/server, file pointer, encryption, digest, non-blocking testing
and null.
Data structures
A dynamically growing hashing system
A simple stack.
A Configuration loader that uses a format similar to MS .ini files.
Provides general cryptographic and X.509 support needed by SSL/TLS but
not logically part of it.
openssl:
A command line tool that can be used for:
Creation of RSA, DH and DSA key parameters
Creation of key parameters
Creation of X.509 certificates, CSRs and CRLs
Calculation of Message Digests
Encryption and Decryption with Ciphers
SSL/TLS Client and Server Tests
Calculation of message digests
Encryption and decryption
SSL/TLS client and server tests
Handling of S/MIME signed or encrypted mail
And more...
INSTALLATION
------------
To install this package under a Unix derivative, read the INSTALL file. For
a Win32 platform, read the INSTALL.W32 file. For OpenVMS systems, read
INSTALL.VMS.
Read the documentation in the doc/ directory. It is quite rough, but it
lists the functions; you will probably have to look at the code to work out
how to use them. Look at the example programs.
PROBLEMS
--------
For some platforms, there are some known problems that may affect the user
or application author. We try to collect those in doc/PROBLEMS, with current
thoughts on how they should be solved in a future of OpenSSL.
See the appropriate file:
INSTALL Linux, Unix, etc.
INSTALL.DJGPP DOS platform with DJGPP
INSTALL.NW Netware
INSTALL.OS2 OS/2
INSTALL.VMS VMS
INSTALL.W32 Windows (32bit)
INSTALL.W64 Windows (64bit)
INSTALL.WCE Windows CE

LEGALITIES
----------
A number of nations, in particular the U.S., restrict the use or export
of cryptography. If you are potentially subject to such restrictions
you should seek competent professional legal advice before attempting to
develop or distribute cryptographic code.
