I am implementing a user change password feature. However i don't want user to be able to use old past word for the new one. I store the old hashed password in a past_password table.

now i need to compare the newly enter password from user to his/her past password

i understand Hash::make generates a different hash even if the input is the same, i know you can use Hash::check to compare the old and new password

however is this the only way? this would mean i have to select ALL past passwords and call Hash:check one at a time to make sure there is no repeat.

With old hashing algo i could of just do a database select to find out if the new match the past hashed password

anyone have any suggestions?
