小巧快速的加密文本文件的工具，采用RC4算法，支持256个字符长度的密码，-compact rapid text file encryption tool, using RC4 algorithm, support 256 characters in length of the password,

代码详细的将DES算法的加密过程描述详细，通过MFC进行界面化操作，整体界面良好，具有很强的可读性和很好的独立性，突出了C++的封装型和继承性的有点，值得参考。。。。。。。。。。。。。。。。

PGP Software Development Kit Cryptographic Module  Operational Test Notes WHAT IS IT? ---------- The optest program is used as part of the FIPS 140-2 validation process. In particular, section  TE03.14.02  which requires that the tester shall perform each of the specified services and observe that that they have been implemented  properly.   As a side benefit to clients of the  SDK this code can also be used a good example of how to perform a number of commonly used functions, whether or not the developer intends to run in FIPS mode.   Depending on what option is chosen from the command line the following tests will be run: FIPS MODE SPECIFIC TESTS ------------------ - Invoke the Approved mode of operation (optest.c)     This involves Initializing the SDK, checking

MD5的全称是Message-digest Algorithm 5（信息-摘要算法），用于确保信息传输完整一致。本程序是c语言版的md5加密解密源码！-The full name of MD5 is Message-digest Algorithm 5 (Information- Summary of algorithm), to ensure the integrity of the information transmission line. This procedure is the c language version of the md5 encryption source code!
