Package adler32 implements the Adler-32 checksum.

It is defined in RFC 1950:

Adler-32 is composed of two sums accumulated per byte: s1 is
the sum of all bytes, s2 is the sum of all s1 values. Both sums
are done modulo 65521. s1 is initialized to 1, s2 to zero.  The
Adler-32 checksum is stored as s2*65536 + s1 in most-
significant-byte first (network) order.

函数

func Checksum

1

func Checksum(data []byte) uint32

Checksum returns the Adler-32 checksum of data.

func New

1

func New() hash.Hash32

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.
