What is the key difference between hashing and encryption?

• A.Hashing is a reversible encoding that cannot hide a PAN, while encryption is a one-way digest that stores a fixed-length fingerprint of the original data
• B.Hashing is a symmetric process that cannot use a salt, while encryption is an asymmetric process where one public key decrypts the stored data later
• C.Hashing is a transport protocol that cannot protect stored PANs, while encryption is a storage format where keys are derived from the card number
• D.Hashing is a one-way process that cannot be reversed, while encryption is a two-way process where data can be decrypted back to its original form
