[erlang-questions] CRC32c in Erlang?

[Gulyás Attila]

CRC32 and CRC32c are not the same.

Thomas Cioppettini did a lot of work collecting info in Cowboy issue #1340,
and also did an Erlang and Elixir implementation in a Github gist.

Found Erlang NIF bindings (seem to be forked from the same root):
