Hi! My question is probably very simple, but I need to ask.

I encoded my string with password_hash in my PHP page, but now I need to encode a string in my C# Windows Forms Application.

For example, "garchomp9" would be equal to "$2y$10$opiDs.kbUEN6HUPzYCHyX.cOVQt5BvWrqWMrSkXHlP7d91.9aERfK"

Any help?

What I have tried:

Sadly, I have deleted my code accidentally.(My PC got shut off..)

Short answer: You don't decode a hash because it is not reversible.
A hash is not encryption, hash is specially designed to prevent 'unhashing'.
Hash function - Wikipedia[^]
As stated in php manual, the php feature can change over time.
If you want same hashing over php and C#, you need to choose a hashing algorithm/library that will be available in both languages.

Well, is there a library that will provide the same output as password_hash, or is that a php-exclusive function?

PHP: password_hash - Manual[^]

Use BCrypt to Hash Your Passwords: Example for C# and SQL Server[^]

The first link allows to state that default password hash algorithm is bcrypt.

The second link is an article on CP which deals with the subject.
