DES完整地展示在下编译通过的程序环节。

计算文件hash值的源代码，包含crc,md2,md4,md5,sha,sha1,sha256,ra-Calculated hash value of document

RSA实现数字签名算法 VC++实现，有图形化窗口-Digital Signature Algorithm to RSA

SHA-1Hash函数源码，可以对任何文件做Hash，得到的Hash值为160位。具有抗强碰撞，弱碰撞等能力。虽然王小云已经找到了个别碰撞。但在新的好的hash函数出来之前仍将被广泛使用。-SHA-1Hash function source, any document can be done right hash, the hash value of 160. Anti-collision, the weak capabilities of the collision. Although Bruce Schneier, had found individual collisions. But the new good hash function will be out before widespread use.
