WebCTR (Counter) : This mode uses the value of a counter as an IV. It's very similar to OFB, but it uses the counter to be encrypted every time instead of the IV.

WebMar 29, 2024 · 1 Answer. This is a weird assertion. A block cipher in OFB mode is, functionally, a stream cipher which produces a key-dependent stream of pseudorandom bytes; encryption is then just a XOR of the stream with the data to encrypt (and decryption is identical). Data size is quite irrelevant; to the contrary, OFB is one of these modes which … WebJan 27, 2024 · Output feedback (OFB) mode is a block cipher mode of operation that turns a block cipher into a synchronous stream cipher.
