按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model

DES算法实现，非常有用，对于研究加密的朋友希望回有帮助-DES algorithm, very useful for research encryption friends want to return to help

数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.

此小程序是MD5的加密算法，里面有详细的注释！-This small program is MD5 encryption algorithm, there are detailed notes!

一个移动客户端与服务端安全交互的解决方案。 针对: http://my.oschina.net/kaster/blog/130940 客户端使用AES加密报文，使用RSA公钥加密AES密钥 服务端使用私钥解密AES密钥，再使用AES密钥解密密文 隐掉了数据压缩部分(A mobile client and server security solutions that interact. For: http://my.oschina.net/kaster/blog/130940 client packets using AES encryption, RSA public key encryption using AES key server uses the private key to decrypt the AES key, then use the AES decryption key Man hidden away part of the data compression)

采用bin加密的经典算法。-bin encryption using the classical algorithm.

OpenVPN is a robust and highly flexible tunneling application that uses all of the encryption, authentication, and certification features of the OpenSSL library to securely tunnel IP networks over a single TCP/UDP port.

实现在WP端silverlight的AES加密采用ECB加密方式和paddingpkcs#5的填充方式。 silverlight中的AESmanaged只有CBC加密方式和paddingpkcs#7的填充方式。(Achieve the WP side silverlight ECB encryption using AES encryption methods and paddingpkcs# 5 is filled. silverlight in AESmanaged only CBC encryption mode and paddingpkcs# 7 is filled.)

使用单片来进行CRC校验，可以位校验、半字节和字节校验-Using the single-chip to carry out CRC check, you can place check, half-byte and byte checksum
