快速取模指数算法，C++编写，下载即可编译运行，RSA算法里面需要用到的(Take the fast modular exponentiation algorithm, C++ to prepare, you can compile and run the download, the RSA algorithm which need)

C++ implementation for S26

playfair 加密算法的实现，用一个例子做了展示(realize playfair algorithm，use a sample to show the algorithm)

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

说明：  信息安全相关，经典加密算法A5，通过编译(Information security-related, classic encryption algorithm A5, through compiler)

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. )

Elgamal数字签名的一个大体验证,用于对一个文件的签名后在进行认证.一个VC开发的小程序.(Elgamal digital signature verification of a general for the signature of a document during the certification after. A small VC development process.)

对于ECC 进行加密解密运算，这里主要是ECDSA的签名(For ECC encryption and decryption operations, where mainly ECDSA signature)
