Seems like a good idea to me. The current code doesn't crash and doesn't
generate an error return. Is there any other useful thing that a NULL key
I don't have a big picture view. Is there any reason that all of the crypto
init type procedures can't keep the current key schedule if called with a NULL
Am I the only one (so far) that is interested in reusing the current key
schedule to save CPU cycles?
These are my opinions. I hate spam.
