Hm, I'm not familiar with OpenBSD's crypto layer, but CTR mode should
not require padding. Perhaps its a limitat

Oh wow my applied cryptography second edition is getting old. ;) There is no

Hi,
I'm looking for a stream cipher in the kernel that is fairly secure. Does it
exist? Alternatively I'm looking for a block cipher that does CFB
(Cipher Feedback Mode). There is a prototype stub for DES CFB in
/sys/crypto/des.h but I don't see a des.c file in the 3.9 sources, is it taken
