Encryption algorithm with decryption?

Question

Encryption

There is a task - to put passwords in the cipher form in an Oracle DB.
The PHP application must be able to retrieve this data and decrypt the .
The classic scheme applicable to the web with one-way encryption through an algorithm like md5 with a salt is not suitable - it is password decryption that is needed .
What tools can be used to do this?

Answer 1

Offhand - we encrypt passwords with some key (password) using any suitable algorithm.
We decrypt on the PHP side with the same key.
There are hundreds of algorithms, classic - AES, you can GOST, you can Kuznechik (yes, there is one), you can any other that is supported in PHP.
This is hashing.
