I'm having problems, at the time of making and passing the hash pass to password_hash () to do the validation using password_verify ();
The fact is that I have changed the php version to the last one, and can not log in. Your registration has been with hash ('sha512') and now I have validated the password with password_verify, but it does not validate it, so I want to make a statement in the database to pass those passwords to password_hash () as I would have to do?
