@ -116,8 +116,10 @@ The :mod:`binascii` module defines the following functions:
.. function:: crc_hqx(data, value)
Compute the binhex4 crc value of *data*, starting with *value* as the
initial crc, and return the result.
Compute a 16-bit CRC value of *data*, starting with *value* as the
initial CRC, and return the result. This uses the CRC-CCITT polynomial
*x*:sup:`16` + *x*:sup:`12` + *x*:sup:`5` + 1, often represented as
0x1021. This CRC is used in the binhex4 format.
.. function:: crc32(data[, value])
