使用来加减密的，是RSA和MD5的复合使用的源码！-Secret used to addition and subtraction, is a composite RSA and MD5 to use source code!

S-DES编程S-DES加密采用8和10明文作为密钥输入，有8个密文作为输出。使用同一密钥进行加密和解密。要求：CBC模式到解密版本增加。对话界面：在目录选项中选择加密或解密密钥输入明文或密文文档（对于二进制内容，。Txt文件，），建议加密或解密已完成2。输出：产生密文或明文文本3。提供：文档、源代码、可执行文件，通过加密实验得到运行结果。4分析雪崩效应文件：键下同一个显式改变文本在闭合处的差异，在同一个地方显式改变电位器在密文处的情况

MD5 加密算法 Delphi 源码。 编译为dll文件，方便其他语言的系统调用-MD5 encryption algorithm Delphi source. Dll file to compile and facilitate language system calls

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).
