jukivili added a comment to D493: AES block modes for PPC.

Have you considered working on bulk CFB-decryption and OCB-enc/dec? Those are the block cipher modes used by GnuPG (OCB is new AEAD mode to be used starting with 2.3).

jukivili added a comment to D493: AES block modes for PPC.

ECB is not bulk optimized in libgcrypt. I've send patches to add this in past but this was rejected on grounds that ECB is insecure and should not be used.
