How to display and decrypt password in yii2?

Question

Yii

actually a subject: it is
necessary to pull out passwords of users from base.

Answer 1

They are hashed in a special way to make the procedure you want impossible.
Hashing is a one-way process.
So the short answer to your question is no.
Long answer - if some users used dictionary or fairly simple passwords + your salt was not unique for each password - then there is a chance to generate a rainbow table and pick up some of the passwords in this way. It is impossible to find out what the password actually was with 100% probability purely because of how the algorithm works, you can pick up a password that will give the same hash, but this will not necessarily be a real password.

Answer 2

If the Security component was used in the project, then inside bcrypt and automatic good salt generation through a reliable source of entropy. So:
1. You can immediately exclude the use of rainbow tables.
2. Search will be long. Even in a short dictionary. bcrypt is resource intensive.
In general, almost nothing.
If Security has not been used, this may be possible.
