一个实现DES加解密算法的小程序，编程实现DES算法的加密过程、脱密过程和16个内部密钥生成过程(An implementation of DES encryption and decryption algorithm applet, programming encryption algorithm DES implementation process, from secret process and the 16 internal key generation process)

RSA的JAVA实现,界面很简洁,就三个按钮:生成密钥对,加密文件,解密文件.可以导入文件,但文件长度有限制,这是由于密钥长度而限制的(RSA JAVA interface is very simple, three buttons : Key Generation right, encrypted documents, The declassified document. can import documents, but there are restrictions on the length of documents, as key length restrictions)

说明：  一个彩色视频加密程序，可以实现对彩色视频的加密解密。(A color video encryption program can realize the encryption and decryption of color video.)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)
