To further improve security, password files usually do not contain the hash of the password PWx of user x$.$ Instead, the password file contains two values for each user x: a random value salts, called salt, and the result of hashing of a combination of the password PWx and of the salt. In this question, you are given a file SaltedPs which contains, for each user x$,$ the pair

$($salt$,$ h$($PWxtsaltx$)),$ where salty is a random value chosen for user x$.$
