checkPassword Source

:: Password stored salt and password hash -> String password to test (unhashed) -> Bool did it match check if the submitted password matches the stored password

doHash :: Salt -> String -> PasswordHash Source

hash a password using the supplied salt Originally implemented using SHA1. By switching to pbkdf2, we don't rely on implementation of randomIO being cryptographically secure.

changepass :: Monad m => String -> String -> Password -> m Password Source

genSalt :: MonadIO m => m Salt Source

generate some random salt returns 4 Char of salt.

newPassword :: MonadIO m => String -> m Password Source

generate a new salted/hashed Password from the given input string
