用C写的DES加密的一个算法。是很不错的。-Using C written by a DES encryption algorithm. Is very good.

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

利用Rijndael算法进行任意文件的加密。把任意一个文件分成N个16字节组，最后一组若不足16字节可以用空格去补！-Rijndael algorithm using arbitrary file encryption. To arbitrary N of a document is divided into 16-byte groups, and finally a group of less than 16 bytes can be used to fill space!
