DarwinSSL: allow using NTLM authentication Allow NTLM authentication when building using SecureTransport (Darwin) for SSL. This uses CommonCrypto, a cryptography library that ships with all versions of iOS and Mac OS X. It's like OpenSSL's libcrypto, except that it's missing a few less-common cyphers and doesn't have a big number data structure.

DarwinSSL: several adjustments - Renamed st_ function prefix to darwinssl_ - Renamed Curl_st_ function prefix to Curl_darwinssl_ - Moved the duplicated ssl_connect_done out of the #ifdef in lib/urldata.h - Fixed a teensy little bug that made non-blocking connection attempts block - Made it so that it builds cleanly against the iOS 5.1 SDK

darwinssl: add TLS 1.1 and 1.2 support, replace deprecated functions In Mountain Lion, Apple added TLS 1.1 and 1.2, and deprecated a number of SecureTransport functions, some of which we were using. We now check to see if the replacement functions are present, and if so, we use them instead. The old functions are still present for users of older cats. Also fixed a build warning that started to appear under Mountain Lion

/* In Mountain Lion and iOS 5, Apple made some changes to the API. They
added TLS 1.1 and 1.2 support, and deprecated and replaced some
functions. You need to build against the Mountain Lion or iOS 5 SDK
or later to get TLS 1.1 or 1.2 support working in cURL. We'll weak-link
to the newer functions and use them if present in the user's OS.
Builders: If you want TLS 1.1 and 1.2 but still want to retain support
for older cats, don't forget to set the MACOSX_DEPLOYMENT_TARGET
environmental variable prior to building cURL. */

darwinssl: output cipher with text, remove SNI warning The code was printing a warning when SNI was set up successfully. Oops. Printing the cipher number in verbose mode was something only TLS/SSL programmers might understand, so I had it print the name of the cipher, just like in the OpenSSL code. That'll be at least a little bit easier to understand. The SecureTransport API doesn't have a method of getting a string from a cipher like OpenSSL does, so I had to generate the strings manually.

DarwinSSL: several adjustments - Renamed st_ function prefix to darwinssl_ - Renamed Curl_st_ function prefix to Curl_darwinssl_ - Moved the duplicated ssl_connect_done out of the #ifdef in lib/urldata.h - Fixed a teensy little bug that made non-blocking connection attempts block - Made it so that it builds cleanly against the iOS 5.1 SDK

DarwinSSL: allow using NTLM authentication Allow NTLM authentication when building using SecureTransport (Darwin) for SSL. This uses CommonCrypto, a cryptography library that ships with all versions of iOS and Mac OS X. It's like OpenSSL's libcrypto, except that it's missing a few less-common cyphers and doesn't have a big number data structure.
