vc++写的ElGamal加密系统，能够对简单的数字进行加密。(The ElGamal encryption systems, vc++ write simple digital encryption.)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

说明：  编制程序，将输入的一行字符以加密的形式输出，然后将其解密，解密的字符串序列与输入的正文相比较，吻合时输出解密的正文，否则解密失败。 加密时，将每个字符的ascii码依次反复加上“4962873”中的数字，并在32（‘’）~122（‘z’）之间作模运算。解密与加密的顺序相反。例如输入正文“the result of 3 and 2 is not 8” 结果为： (Programming, the input line character output in an encrypted form, and then decrypted, the decrypted text sequence of characters compared with the input, output to decrypt the body of the agreement, otherwise the decryption failed. Encryption, ascii code of each character in turn repeatedly with &quot 4962873&quot in the figures, and 32 (' ' )~ 122 (' z' ) as a model between the operations. Decryption and encryption in reverse order. For example, enter the text &quot the result of 3 and 2 is not 8&quot results:)

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)

这是一个小程序,凯撒解密,自己写的,以后还会扩展的(This is a simple program for a example of ceasar cipher. It is produced by myself and I want to extend it to a substitution cipher program in some days.)

ras加密实现,图形界面.源码附有注释，方便理解。欢迎下载(ras encryption to achieve, graphical interface. annotated source code to facilitate understanding. Welcome to download)

帮助开发出来的程序加密和解密！采用MD5算法，即时数据库中被人盗窃，也不能得到用户登录密码(Developed procedures to help encrypt and decrypt! Using MD5 algorithm, real-time database which has been stolen, nor can the user login password)

文件的加密传输，用到了各种加密算法 MD5 RSA (File encryption MD5 RSA )

现代密码学课设——SHA（安全哈希算法Secure Hash Algorithm）算法编程(failed to translate)

DES加密的雪崩效应分析，按照作业要求做的。(DES encryption of the avalanche effect analysis, done in accordance with operational requirements.)
