Implement reused secret keys for Noise/X3DH/etc protocols #71

Closed isislovecruft closed 2 years ago

isislovecruft commented 3 years ago

This implements secret keys which are technically reusable, but discouraged from reuse due to not having serialisation methods, in order to facilitate certain keying constructs in the Noise protocol and others which require doing Diffie-Hellman operations more than once with a single somewhat-ephemeral key. (cf. #57)

Thanks @rozbb! I've implemented your suggestions above.
