I'm developing encrypted comms between my ColdFire-based system and a ZC3.9. Unencrypted comms work fine, but I get a returned sw1sw2 of 66C3, "...authentication bytes in a command were invalid." Can you provide any clues about where I should look first to solve it? I'm using an encryption package from the FSF.
