Ontology	Electronic File Formats Error detection and correction CRC-16

CRC-16 is a broad family of CRC (cyclic redundancy check) algorithms that produce a 16-bit result.

Refer to the CRC article for more information.

Specific algorithms

Selected CRC-16 algorithms are listed here. The names are from the CRC RevEng Catalogue.

CRC-16/ARC

Also referred to as CRC-16-IBM.

The CRC of ASCII "123456789" is 0xbb3d.

Used by ARC, LHA, StuffIt, Zoo, ArcFS, Spark.

CRC-16/XMODEM

This is a form of CRC-16-CCITT, though it may be inaccurate to refer to it by that name.

The CRC of ASCII "123456789" is 0x31c3.

Used by MacBinary, BinHex, LBR.

CRC-16/IBM-3740

Same as CRC-16/XMODEM, except that it is initialized to 0xffff instead of 0x0000.
