crc32

Documentation

Overview

Package crc32 implements the 32-bit cyclic redundancy check, or CRC-32, checksum as implemented by the Terraonion MegaSD cartridge.

It uses the standard CRC-32 normal polynomial but computes the CRC in a slightly different way.

Functions

func Checksum

func Checksum(data []byte) uint32

Checksum returns the CRC-32 checksum of data.

func New

func New() hash.Hash32

New creates a new hash.Hash32 computing the CRC-32 checksum. Its Sum method will lay the value out in big-endian byte order.

func Update

func Update(crc uint32, p []byte) uint32

Update returns the result of adding the bytes in p to the crc.
