It is not true to say that that which is encrypted cannot be unencrypted and that the only use case for encryption is doing things like encrypting a would-be answer for "What is the password?" to attempt to match it against an encrypted password at a database. Data may be encrypted and then decrypted using a key. An encoding also of course may be decoded, but the distinction is that anyone may decode an encoding without knowing a key. What is more, the mapping-to-something-all-but-impossible-to-reverse-engineer in the password scenario I just mentioned would typically be thought of as hashing and not encrypting.
