 ## J	What I should have learnt from this lab?
 The key things learnt:
 
-•	How to encrypt and decrypt with symmetric key encryption, and where we use a passphrase to generate the encryption key.
-•	How padding is used within the encryption and decryption processes.
-•	The core difference between a block cipher and a stream cipher.
