Goofs happen, man.  :)

Also, a note for anyone who's confused (what's CTAK? does GnuPG use CTAK
or CFB for symmetric encryption? etc.): CFB stands for "Cipher
Feedback", which is a particular mode of operation for symmetric
ciphers.  CTAK is "Ciphertext Autokey", which is the exact same thing by
another name.
