nmax is the largest n such that 255 * n * (n+1) / 2 + (n+1) * (mod-1) <= 2^32-1. It is mentioned in RFC 1950 (search for "5552").

digest type #
digest represents the partial evaluation of a checksum. The low 16 bits are s1, the high 16 bits are s2.
type digest uint32Functions
AppendBinary method #
func (d *digest) AppendBinary(b []byte) ([]byte, error)BlockSize method #
func (d *digest) BlockSize() intChecksum function #
Checksum returns the Adler-32 checksum of data.
func Checksum(data []byte) uint32MarshalBinary method #
func (d *digest) MarshalBinary() ([]byte, error)New function #
New returns a new hash.Hash32 computing the Adler-32 checksum. Its Sum method will lay the value out in big-endian byte order. The returned Hash32 also implements [encoding.BinaryMarshaler] and [encoding.BinaryUnmarshaler] to marshal and unmarshal the internal state of the hash.
