Hi. This is probably a stupid question, but we have been migrating our forum from XenForo over to Discourse. We have a backend server for authorization which involves connecting to the database and verifying credentials against the users table. XenForo’s bcrypt algorithm worked as expected, and wit…

Nevermind. I had to use the hex representation of the salt as the argument, not the decoded salt like I was doing in the post above. Now the hashes are equal.

Are you using the migrate password plugin?

[изображение] polyzium: I tried various different implementations of PBKDF2 algorithm, but they all output the exact same (different from Discourse’s) hash. Have you tried openssl’s implementation? That’s what we use (you can see it in discourse/lib/pbkdf2.rb). As an example, after setting a…

We primarily used Go’s crypto/bcrypt implementation for Xenforo. The same hashes from various pbkdf2 algorithm implementations suggests me that Go possibly stores strings or casts strings to bytes in a somewhat different way. I’ll have to try that tomorrow (it’s late over here). If OpenSSL gives me…

Do you have a short example test case? E.g. if you use the info above, what do you get?

Sorry, I am currently not in a position to tell you as timezones are annoying. It’s very late out here and I could only do so next day.

I did as you asked. The password is swordfish#98765. Database entry: discourse=> SELECT password_hash, salt, password_algorithm FROM users WHERE id=1; password_hash | salt | password_algorithm -------------…

No, at least not that I am aware of. are you talking about this?
