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.
