【Python】对密码文本进行加密, 并判断 hashlib

import hashlib


def encrypt_password(password, salt):
    # 创建一个sha256的哈希对象
    sha256_hash = hashlib.sha256()

    # 将盐值和密码组合起来并进行哈希
    hashed_password = salt.encode('utf-8') + password.encode('utf-8')
    sha256_hash.update(hashed_password)

    # 获取哈希结果
    encrypted_password = sha256_hash.hexdigest()

    return encrypted_password


def verify_password(password, salt, encrypted_password):
    # 对输入的密码进行加盐加密
    new_encrypted_password = encrypt_password(password, salt)

    # 比较加密后的密码和存储的加密密码是否一致
    if new_encrypted_password == encrypted_password:
        return True
    else:
        return False


if __name__ == "__main__":
    password = input("Enter your password: ")

    # 生成盐值
    salt = 'yanzhi'

    # 加密密码
    encrypted_password = encrypt_password(password, salt)
    print("Encrypted password:", encrypted_password)

    # 验证密码
    entered_password = input("Enter password again: ")
    if verify_password(entered_password, salt, encrypted_password):
        print("Password is correct")
    else:
        print("Password is incorrect")
