    CFB mode can be used to convert block ciphers into stream ciphers. Ciphertext refers to encrypted text transferred from plaintext using an encryption algorithm, or cipher.
    In CFB mode the initialization vector is encrypted and the output is then xor'd with the plaintext stream. The result is then used as the initialization vector for the next round. Errors will affect the current block and the next block.
