		Package crc64 implements the 64-bit cyclic redundancy check, or CRC-64,
		checksum. See https://en.wikipedia.org/wiki/Cyclic_redundancy_check for
		information.


Package-Level Type Names (only one)


	/* sort by:  |  */
	
		Table is a 256-word table representing the polynomial for efficient processing.

		
			func MakeTable(poly uint64) *Table
		
			func Checksum(data []byte, tab *Table) uint64
			func New(tab *Table) hash.Hash64
			func Update(crc uint64, tab *Table, p []byte) uint64




Package-Level Functions (total 4)


	
		Checksum returns the CRC-64 checksum of data
		using the polynomial represented by the [Table].


	
		MakeTable returns a [Table] constructed from the specified polynomial.
		The contents of this [Table] must not be modified.


	
		New creates a new hash.Hash64 computing the CRC-64 checksum using the
		polynomial represented by the [Table]. Its Sum method will lay the
		value out in big-endian byte order. The returned Hash64 also
		implements [encoding.BinaryMarshaler] and [encoding.BinaryUnmarshaler] to
		marshal and unmarshal the internal state of the hash.


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




Package-Level Constants (total 3)


	
		The ECMA polynomial, defined in ECMA 182.


	
		The ISO polynomial, defined in ISO 3309 and used in HDLC.


	
		The size of a CRC-64 checksum in bytes.
