DES

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

一个用vc编写的aes算法实现，含有128，192，256三种钥匙长度的(a prepared using vc Orangk'aes algorithm, containing 128,192,256 length of the three key)

生成RSA密钥，将密钥生成后`，存入文件中(RSA key generation, key generation `stored in the file)

讲述des加密过程，实现了简易锝des加密算法(About the des encryption process to achieve a simple encryption algorithm technetium des)

vigenerecipher加密解密算法实例 使用vigenerecipher算法加密字符串 可输入任意密钥(vigenerecipher examples of encryption and decryption algorithms String encryption algorithm using the vigenerecipher Can enter any key)

基本的DES加密算法，可以实现一些基本的功能，但是大型计算不适合(The basic DES encryption algorithm)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

说明：  ECC实现加密解密功能，系统参数的生成！(ECC to achieve encryption and decryption functions, system parameter generation!)
