Expand description

§HPKE

This is originally a fork of hpke-rs and heavily modified.

hpke-core: HPKE core functionality.
hpke-crypto: cryptographic backend implementations for HPKE.

Currently supports the following:
- backend-aws-lc: uses aws-lc-rs as the cryptographic backend.
- backend-graviola: uses graviola as the cryptographic backend.

Licensed under MPL-2.0 license.
