In Password based encryption (PBE), a password is chosen and it is used along with a generated salt (key) to encrypt. It's safer to hash the password, then, and just re-calculate the hash code than it is to store an encrypted password which could possibly be decrypted. In Password based encryption (PBE), a password is chosen and it is used along with a generated salt (key) to encrypt.

In other words, we want a function that tells us if the entered password is correct or not: The above uses the original salt string and a plaintext password in question to generate a hashed password which is compared against the previously-generated hash key. From that point on, the only person who can unlock the box is me, with my private key.
