以前发的那个只实现了SHA-1, 现在补全了, sha-160, sha-224, sha-256, sha-384, sha-512

SHA家族加密算法实现方式, C语言版本-SHA algorithm

本程序包括一些常用的加密算法，包括：SHA-1,SHA-224,SHA-384,SHA-512等-This process includes some commonly used encryption algorithms, including: SHA-1, SHA-224, SHA-384, SHA-512, etc.

通过vc,MFC方式实现了 sha1,sha224,sha256,sha384,sha512的算法，计算原文可以使用字符串和文件。提供字符大小写转换功能-In vc, MFC way to achieve the sha1, sha224, sha256, sha384, sha512 the algorithm to calculate the original strings and files can be used. Character case conversion functions
