stackadler32

Note: This is a fork of github.com/sent-hil/adler32 that provides digests that are allocated on the stack and can be incrementally written to. This is useful for places where you perform concurrent checksumming and there's no good place to cache a digest without needing to acquire it expensively (under lock, etc).

Port of adler32 checksum function as described here: https://www.ietf.org/rfc/rfc1950.txt to Go.

Example:

 adler32.Checksum([]byte("Hello World"))
