Encryption isn't encryption if it's one-way.

Thanks, I was trying to rephrase it, similar to people using IM in this thread but being off-base with it's actual meaning.

Encryption means encrypting information which can later be decrypted. If you are talking about a one-way transform of data that you can never retrieve the original information from the result of the transformation, that is called hashing. We hash passwords, not encrypt them.
