For secret keys encryption in OpenPGP, the IV provided is always 8 octets. The spec just says "use CFB mode with the 8-octet IV". I've tried padding either size with 0's to make unCfb accept it, but that doesn't seem to work. What's the right way to do this?

Nevermind. I must have had too much sleepdep. That's not what the spec says at all.

OK, thanks for closing the loop. I had a vague intention of looking into this, but since it was counter to my mental definition of CFB mode I wasn't moving quickly.
