Subject Best Home for Checksum Implementations?
Date Tue, 24 Jan 2017 09:08:11 GMT
Hi

inside of [compress] we've already got an implementation of CRC32C (used
by Snappy, "borrowed" from Hadoop) and will soonish have xxhash32 (used
by LZ4).

I was wondering whether these implementations would belong in one of the
other components (as well as - rather than instead of - compress) but
I'm not sure where it would fit.

[codec] and [io] could be candidates but neither holds any
java.util.zip.Checksum implementations as of now.

Neither CRC32C nor xxhash32 are cryptographic hashes so using codec's
digest package feels wrong.

Stefan
