推荐答案

单向加密背后的整体思想是生成一个无法解密以显示原始字符串的散列值。


这就是处理丢失密码的原因，管理员通常会将其重置为新值。

The whole idea behind a one way encryption is to generate a hashed value that cannot be decrypted to reveal the original string.

That''s the reason that when dealing with lost passwords administrators typically reset it to a new value.

md5是应该是单向加密。您使用它的原因是只有用户知道他们的密码，但您仍然可以验证密码。

如何验证它是创建用户提供的密码的md5哈希值，并将其与数据库中密码的md5哈希值进行比较。


例如：伪代码

md5 is supposed to be a one way encryption. The reason you use it, is so only the user knows their password, but you can still validate the password.
How you validate it is to create an md5 hash of the password supplied by the user, and compare that with the md5 hash of the password in the database.

eg: pseudo code
