Yes, it does indeed seem to be fixed. Seeing that OFB and CFB are pretty fundamental, shouldn't a fix like that merit a b4 release, particularly considering how long it's been since b3? :) John On Thursday, October 17, 2002, at 05:34 PM, Richard Levitte - VMS Whacker wrote: In message

Hmm, I just noticed this problem yesterday, as well. As a temporary work-around, you can turn off padding with OFB mode, and everything works as expected. I'm pretty sure I got an error related to block alignment when I turned off padding in CFB mode. However, the CFB mode behavior is now
