affine
- 1）用C\C++语言实现单表仿射（Affine）加/解密算法； 2）用C\C++语言实现统计26个英文字母出现频率的程序； 3）利用单表仿射加/解密程序对一段较长的英文文章进行加密，再对明文和密文中字母出现的频率进行统计并作对比，观察有什么规律。-1) C \ C++ language to achieve a single table Affine (Affine) encryption/decryption algorithm 2) C \ C++ language stati

authcode
- 动态密钥 把动态密匙保存在密文里，同样的明文，生产不同密文后能解密。加密后的密文可能是一些特殊字符，复制过程可能会丢失，所以用base64编码-Dynamic Key The dynamic key is stored in the ciphertext, the same plaintext, after the production of different ciphertext can be decrypted. Encrypted ciphertext may be some s
