ABSTRACT:
Techniques for generating cyclic redundancy check (CRC) values are provided. Bit messages that are to be transmitted to recipients are aligned to desired byte boundaries for purposes of generating CRC values, which are to be sent with the bit messages. The CRC values are rewound or adjusted back to values associated with original lengths of the bit messages before the CRC values are transmitted or forwarded with the bit messages to recipients.
