It is common to store … WebHash the PAN + long, systemwide cryptographic pepper (secret salt) The pepper will add enough entropy to make brute force impossible without knowing the key. Store the pepper outside of the database. To check for a match, perform the hash on the PAN of interest, then search the table. Because the secrets are all systemwide, you should be able ...
