FWIW: The SYNC bug-feature is not used if MDC is in use.  We use CFB128
for all ciphers with a blocklength of 128.

With that in mind I added OCB to Libgcrypt last week.  For free
implementations it is thus no problem to replace CFB+MDC-hack by OCB.  I
am not sure how the free OCB licenses relate to the use of an LGPLed
library in a military application - but to me that is more a feature
than a problem.

Another reasons to re-establish the OpenPGP WG.
