这是一个jsp的的项目。用于支付宝接口开发的MD5加密算法，详细的内容在里面   。

md5算法，实现给一个512bir数据块加密，程序有详细的注释，-md5 algorithm, to realize a data block encryption 512bir, procedures have detailed notes,

一篇09年很不错的关于密码学的论文，是从IEEE上下载的，内容很权威-A very good 2009 paper on cryptography and is downloaded from the IEEE, the content is authoritative

sha1sum验证算法,cd分发映像文件的，sha1值得计算，验证sha1-sha1sum verification algorithm, distributed cd image files, sha1 worth calculation, the certification sha1

KEELOQ_ENcode　简单的加密程序，可惜就是没有源代码。-KEELOQ_ENcode simple encryption program, but is not the source code.

写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但.ENC引伸。-Write an exclusive-OR encryption program. The program should take as input a filename that is then encrypted by the program. The program should ask the user to input an encryption key, which should be used to encrypt the file. The output of the program should go into a file with the same filename but a .ENC extension.
