feistel密码

The Feistel Cipher is a structure used to create block ciphers. It has many rounds of encryption to increase security. In each round, different techniques are applied to the plain text to encrypt it. Each round has one substitution technique. The plain text after passing through all these rounds gets converted into the Ciphertext. The complete process of the encryption is explained as follows,

Feistel密码是用于创建分组密码的结构。 它具有多轮加密以提高安全性。 在每一轮中，将不同的技术应用于纯文本以对其进行加密。 每回合都有一种替代技术。 经过所有这些回合后的纯文本将转换为密文。 加密的完整过程说明如下：
