DES加密算法的C++

RC4 encryption algorithm implementation

简单的密码的例子，使用VB的源码, 非常简单明了，希望大家喜欢。-Simple Example of VB Source Code for Encrypt, Rudimentary encryption/decryption demo program

DES算法全称为Data Encryption Standard,即数据加密算法,DES算法把64位的明文输入块变为64位的密文输出块,它所使用的密钥也是64位。RSA的安全性依赖于大数分解。公钥和私钥都是两个大素数（ 大于 100个十进制位）的函数。本程序为适合初学者的rsa算法java源码及des源码，开发环境eclipse3.4-DES algorithm called the Data Encryption Standard, that is, data encryption algorithm, DES algorithm to express the 64-bit input block into a 64-bit output ciphertext block, it is also used 64-bit key. RSA" s security depends on the decomposition of large numbers. Public key and private key are two large prime numbers (more than 100 decimal places) of the function. This procedure is suitable for beginners of rsa algorithm java source and des-source, development environment eclipse3.4
