Migrating ASP.NET users' hashed passwords to Laravel
I am working on a project that is currently built on ASP.NET MVC. I am not very familiar with ASP, but i have dug around and gathered that they are using dotnetOpenAuth for the auth system. In the DB, there is obviously the hashed password, but my question is if it's possible to decode these passwords using PHP?
Otherwise, is my only option decoding them in the current ASP framework, creating a duplicate user table with unhashed passwords, then running that through the Laravel code and hashing the unhashed passwords using PHP hashing?
You could create a small api function to check passwords against the .NET function, if it passes hash and store the password the user has entered in your Laravel application. Or you could just send out an email to all users with a temporary password and ask them to change it, but that might give out the wrong signal to your users with all these data-breaches these days.
And I hope that those passwords can't be decoded because they used an one way hash?
