Block cipher mode of operation – Wikipedia

The output feedback (OFB) 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. Just as with other stream ciphers, flipping a bit in the ciphertext produces a flipped bit in the plaintext at the same location.

OFB mode is output feedback mode. The mode was originally specified by NIST in FIPS 81. The standard, issued in 1980, …

What is OFB? – Educative.io

OFB (short for output feedback) is an AES block cipher mode similar to the CFB mode. What mainly differs from CFB is that the OFB mode relies on XOR-ing …
