Michel, merci beaucoup, for the explanation.

It does clear things up for me.  I appreciate it,

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.

Is there any good rule of thumb for when to use:

*-k * versus

*-K *

Also, what does the term IV refer to in reference to *-iv IV*?

Thanks in advance,
