CFB: The Cipher-Feedback Mode (in 8bit). This is a self-synchronizing stream cipher implemented from a block cipher. This is the best mode to use for encrypting strings or streams. This mode requires an IV.

OFB: The Output-Feedback Mode (in 8bit). This is a synchronous stream cipher implemented from a block cipher. It is intended for use in noisy lines, because corrupted ciphertext blocks do not corrupt the plaintext blocks that follow. Insecure (because used in 8bit mode) so it is recommended not to use it. Added just for completeness.

nOFB: The Output-Feedback Mode (in nbit). n Is the size of the block of the algorithm. This is a synchronous stream cipher implemented from a block cipher. It is intended for use in noisy lines, because corrupted ciphertext blocks do not corrupt the plaintext blocks that follow. This mode operates in streams.

nCFB: The Cipher-Feedback Mode (in nbit). n Is the size of the block of the algorithm. This is a self synchronizing stream cipher implemented from a block cipher. This mode operates in streams.
