AES(Advanced Encryption Standard)是一种常用的对称加密算法,PyCryptodome库提供了对AES的支持。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 from Crypto.CipherimportAESfrom Crypto.Randomimportget_random_bytes # 生成16字节的随机密钥 key=get_random_bytes(16) ...
全称:数据加密标准( Data Encryption Standard ),属于对称加密算法。 DES是一个分组加密算法,典型的DES以64位为分组对数据加密,加密和解密用的是同一个算法。它的密钥长度是56位(因为每个第8 位都用作奇偶校验),密钥可以是任意的56位的数,而且可以任意时候改变。 Python代码: import binascii from pyDes import ...
