WebHashing vs Encryption¶ Hashing and encryption both provide ways to keep sensitive data safe. However, in almost all circumstances, passwords should be hashed, NOT encrypted. Hashing is a one-way function (i.e., it is impossible to "decrypt" a hash and obtain the original plaintext value). Hashing is appropriate for password validation. WebIn a one-way hashing operation, the hash function indexes the original value or key and enables access to data associated with a specific value or key that is retrieved.
