NAME

       srccrc - compute CRC checksums of the entire source tree

SYNOPSIS

       srccrc

OPTIONS

EXAMPLES

DESCRIPTION

       Srccrc  traverses  the entire /usr/include and /usr/src tree to run the crc command on all files found.	The result is a long list of file-
       names with their checksums.  The filenames are relative to /usr.

       The command makes an effort to remove most junk files such as .o, .bak and files in bin directories.  It cannot find single  binaries  how-
       ever, so you will have to run make clean in /usr/src to be able to make a crc list that contains only source files.

       Two crc files can be compared easily with the diff command.  A crc list of the original source tree can be found in /usr/src/crclist.

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.
