1.SHA256介绍(可略过) SHA256是SHA-2下细分出的一种算法。SHA-2(安全哈希算法2)是由美国国家安全局(NSA)设计的一组加密哈希函数。SHA-2系列由六个具有224、256、384或512位摘要(哈希值)的哈希函数组成:SH…

The function first encodes the password string as bytes using UTF-8 encoding and then creates a SHA-256 hash object with the hashlib.sha256 method. It then passes the encoded password bytes to this hash object by the update method. Finally, it gets the hexadecimal representation of the hash...
