"WebThere is a problem with using DES as the block cipher in OFB mode, eg: the feedback that goes back into the next round will be encrypted with the same key k resulting back into the plaintext IV used in the first round, and this goes on and on until OFB is done. So the output of the block cipher is deterministic and repetitive. " - Des ofb
