    Subject: CFB mode problems

To who it may concern,

I'm having problems with CFB modes (CFB64 and CFB8) both with DES and
Blowfish. As I could be doing something wrong, I do not know if this is
a bug. However OFB modes (both 8 and 64 bit) work fine. I'm treating
both modes symantically the same and do not know if the problems I'm
having are due to an incorrect symantic treatment of the CFB mode. Sorry
for the bandwidth but I do not know if this is a known problem. The bug
list did not report it. Any comments before I do a bug submital?
