说明: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 algorith <刘洋> 在 2025-01-12 上传

说明: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. Encr <s11111111> 在 2025-01-12 上传
