我需要解密 devise 生成的密码.

I need to decrypt a password generated by devise.

例如，我的密码是test123test.设计生成此密码:

For example, my password is test123test. devise generated this password:

$2a$10$vGeVVu.E0XGjlNEa0xMCK.R0SEH0aFuyJpefrq01Axz6WSbHApPEu 

我需要解密密码并发送test123test.

I need to decrypt the password and send test123test.

推荐答案

你不能，这就是重点.

Bcrypt 将允许您将 test123test 与 $2a$10$vGeVVu.E0XGjlNEa0xMCK.R0SEH0aFuyJpefrq01Axz6WSbHApPEu 进行比较，但它永远不会返回纯文本密码.您可能想问如何破解 bcrypt 加密密码(非常难！我认为几乎不可能)

Bcrypt will allow you compare test123test with $2a$10$vGeVVu.E0XGjlNEa0xMCK.R0SEH0aFuyJpefrq01Axz6WSbHApPEu, but it will never give you the plain text password back. You might want to ask how to crack a bcrypt encrypted password instead (Very hard! Nearly impossible I think)
