- OFB (Output Feedback) mode (NIST SP800-38A)
-
- This mode makes a block cipher into a synchronous
- stream cipher. It generates keystream blocks, which are then XORed
- with the plaintext blocks to get the ciphertext. Flipping a bit in the
- ciphertext produces a flipped bit in the plaintext at the same
- location. This property allows many error correcting codes to function
- normally even when applied before encryption.
