NTLM client source code
HTTP PROXY中NTLM的客户端的C源代码。包含相关的DES等算法在内。Base64的算法，是通过网上共产主义获取，MD4，MD5，HMAC MD5的算法是RFC中提供的，其余的可以根据下面链接的步骤进行编写。我提供一个源代码的例子。其中arith_开头的相关算法，httppc_ntlm是 NTLM的type1、type2、type3消息的应答构成，test_httppc_connect是一个测试的例子，里面没有main函数，但是另外构造一个main函数，在wei_set_proxy_info之后，调用wei_httppc_connect就可以了。详细见http://blog.csdn.net/flowingflying/archive/2009/03/03/3952796.aspx 有朋友说少了头文件，我查了一下，不好意思，少了md.h。请参考下面。 /* Copyright (C) 1991-2, RSA Data Security, Inc.
