Those are the different encryption modes for the algorithm.  IIRC, ECB is 
good if you want to parallize your encryption or you want random access 
to the plaintext from the ciphertext.  CBC is useful if you don't want 
redundant parts of your plaintext to show up as redundant parts of your 
ciphertext.  And CFB is useful to use the algorithm as a stream cipher, 
i.e. you want to decrypt one byte right now, before the rest of the block 
is read in.

Hope that helps.
