Computer encryption is based on the science of cryptography, which has been used as long as humans have wanted to keep information secret. In order to protect sensitive data and distribution we rely on using cryptographic schemes, such as certificates or encryption keys. Thus, cryptography ...
对称加密算法（Symmetric Encryption Algorithm）指的是使用相同的密钥加密和解密消息。我们主要来了解以下几种对称密钥密码的机制。代换密码（Substitution Cipher）是一种加密机制，即用密文替换部分明文。例如，我们替换掉“Hello World”中的一些字母，使其变成“Holly Wyrld”，这里将明文中的“e”用“o”替换，而“...
