散列密码

Question

我正在尝试在将密码发送到数据库之前对其进行哈希处理。 这是我的问题：

i=0
while ( i < len(userList)):
    query = "INSERT INTO login (created, username, password, email) VALUES (NOW(), '" + userList[i][0] + "','" + hashmodel.PasswordHash.new_password_hash(userList[i][1]) + "','" + userList[i][2] + "')"
    i += 1
    settings.database_connection.execute_sql(query)

，密码哈希类如下所示：

class PasswordHash():
def new_password_hash(password):
    hashed = bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt())
    return hashed

首先我在尝试散列未编码的密码时收到错误消息：“Unicode对象必须在散列之前编码”然后当我添加.encode（'utf-8'）时我得到“不能将'bytes'对象隐式转换为str“。

任何人都有解决方案吗？

错误：
