/*
What the key derivation function (Rfc2898DeriveBytes) does is repeatedly hash the user password along with a salt. This has multiple benefits:
1) you can use arbitrarily sized passwords – AES only supports specific key sizes.
2) the addition of the salt means that you can use the same passphrase to generate multiple different.
This is important for key separation; reusing keys in different contexts is one of the most common ways cryptographic systems are broken.
The beauty of this is that every time you encrypt plain text P1 with the derived key, you will get a different cipher text out the other side.
But those different cipher texts can all be decrypted with the same key.
