</ul> <h2 id="pkg-overview">Overview </h2> <p>Package adler32 implements the Adler-32 checksum. </p>
<p>It is defined in RFC 1950: </p>
<pre data-language="go">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.

<li><a href="#Checksum">func Checksum(data []byte) uint32</a></li>
<li><a href="#New">func New() hash.Hash32</a></li>
</ul> <h3>Package files</h3> <p> <span>adler32.go</span> </p> <h2 id="pkg-constants">Constants</h2> <p>The size of an Adler-32 checksum in bytes. </p>
<pre data-language="go">const Size = 4</pre> <h2 id="Checksum">func <span>Checksum</span> </h2> <pre data-language="go">func Checksum(data []byte) uint32</pre> <p>Checksum returns the Adler-32 checksum of data. </p>
<h2 id="New">func <span>New</span> </h2> <pre data-language="go">func New() hash.Hash32</pre> <p>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 <span>encoding.BinaryMarshaler</span> and <span>encoding.BinaryUnmarshaler</span> to marshal and unmarshal the internal state of the hash. </p><div class="_attribution">
