NAME
Digest::CRC - Generic CRC functions
SYNOPSIS
# Functional style use Digest::CRC qw(crc64 crc32 crc16 crcccitt crc crc8 crcopenpgparmor); $crc = crc64("123456789"); $crc = crc32("123456789"); $crc = crc16("123456789"); $crc = crcccitt("123456789"); $crc = crc8("123456789"); $crc = crcopenpgparmor("123456789"); $crc = crc($input,$width,$init,$xorout,$refout,$poly,$refin,$cont); # add data to existing $crc = crc32("ABCD", $crc); # OO style use Digest::CRC; $ctx = Digest::CRC->new(type=>"crc16"); $ctx = Digest::CRC->new(width=>16, init=>0x2345, xorout=>0x0000, refout=>1, poly=>0x8005, refin=>1, cont=>1); $ctx->add($data); $ctx->addfile(*FILE); $digest = $ctx->digest; $digest = $ctx->hexdigest; $digest = $ctx->b64digest;
DESCRIPTION
The Digest::CRC module calculates CRC sums of all sorts. It contains wrapper functions with the correct parameters for CRC-CCITT, CRC-16, CRC-32 and CRC-64, as well as the CRC used in OpenPGP's ASCII-armored checksum.
