python实现希尔密码 希尔密码(Hill Cipher)是一种古典密码学中的分组密码,由美国数学家莱斯利·布鲁斯·希尔(Leslie Bruce Hill)在1929年提出。它是一种多字母替代密码,通过矩阵运算来加密和解密文本。在本文中,我们将介绍如何使用Python实现希尔密码,并提供相应的代码示例。 希尔密码的基本原理是将明文分成多个组,并将...

二、Code 这里把整个加密解密过程封装成类来使用: import numpy as np class HillEncryption: """ :method __init__: 设置秘钥维度 m; 可选传入秘钥 key; 解密秘钥 key_1; 设置填充字符 fillchar(默认"z"); 数字字符映射字典 dic_num_char:{0: "a", ..., 25: "z"}; 字符数字映射字典 dic_char...

Hill Cipher The Hill Cipher is a polygraphic substitution cipher that uses matrix algebra to encrypt and decrypt messages. This implementation of the Hill Cipher in Python uses the NumPy library to perform matrix operations. Installation Clone the GitHub repository: git clone https://github.com/...
