Hi, You need to remember a password. Passwords should never be stored. Keys are binary data (even if they look as text because they are hexa or base64 encoded). Secret keys can be 'derived' from a password to be used when encrypting or decrypting. Sometime you need to store an ENCRYPTED secret key (generally using another password). see https://en.wikipedia.org/wiki/Key_(cryptography). IV means 'Initial Vector', which is random binary data needed to 'start' encryption or decryption. See https://en.wikipedia.org/wiki/Initialization_vector Hope it helps, Regards, Michel.
