MD5加密算法java实现 * 下面这些S11-S44实际上是一个4*4的矩阵，在原始的C实现中是用#define 实现的， 这里把它们实现成为static final是表示了只读，切能在同一个进程空间内的多个 Instance间共享*/ -MD5 algorithm to achieve java* Below these S11- S44 is a 4* 4 Moment RUF, in a primitive realization of the C# define is achieved, Here they become static final realization of the said CD. cut in the same process space within the shared among many Instance* /

算术运算实现字母的替换。凯撒加密就是一种单字母替换法：通过用户给出密钥将字母加上密码变成密文-Arithmetic operations to achieve the replacement of letters. Caesar encryption is the replacement of a single-letter law: the user is given the letter key will be encrypted into a ciphertext

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
