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.
Package-Level Functions (total 2)
Checksum returns the Adler-32 checksum of data.
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.
Package-Level Constants (only one)
The size of an Adler-32 checksum in bytes.
