这个是关于des原吗的文件 是64位的 下次上传个32位的 请大家谅解...

几个密码算法的源代码，不知道有了没有~~ 下的人多了就继续上传-Some source programs of encryption arithmetic.I don t know whether it is always existed or not.I will upload it if a lot of people have downloaded.

PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.

软件模拟CRC冗余校验，可以对任意长度的发送序列求16位校验和，并且可以对接收序列进行检查。有详细的中文注释，和模拟函数-simulation software CRC Redundancy Check, for any length of this sequence for 16 checksum, and to be able to receive sequence for the examination. The Chinese have detailed notes and simulation function

这是一个加密文件的程序，-This is a document encryption procedures,

这个小软件通过在可执行文件(.exe)的尾部添加一个新节(Section)，并且修改PE的入口地址，使可执行文件在运行时，跳出一个输入密码的对话框，从而实现了简单的加密。-small software in executable files (. Exe) to the tail adding a new section (Section), and amend the PE import addresses, so that the executable file is run, jump out of a password dialog box, thus achieving a simple encryption.
