This package contains low-level cryptographic functionality used in other
@cosmjs libraries. Little of it is implemented here, but mainly it is a curation
of external libraries along with correctness tests. We add type safety, some
more checks, and a simple API to these libraries. This can also be freely
imported outside of CosmJS based applications.
