Examples of Signature Key Pairs in PEM format. #18

Closed ehanoc closed 2 months ago

What

As mentioned in https://github.com/derecalliance/protobufs/issues/5, DeRecCryptoInterface#signatureKeyGen the generated keys need to be in PEM format, compliant with RFC-7468.

We need examples to work as documentation and potentially as test vectors

@rsinha @lbaird @johnalanwoods Since we have moved from RSA to ECC, i'm assuming the DeRecCryptoInterface#encryptionKeyGen is unnecessary to document since we would be generating encryption keys based on ECIES, ECDH.

Looks like something we can remove from the interface?

rsinha commented 7 months ago

While it just serves to wrap the underlying ECIES KeyGen, we may want to preserve this function to avoid having the developer to find that implementation, and choose amongst the various crates that implement ECIES. WDYT?

ehanoc commented 7 months ago

Then we could update the interface since ECIES / ECDH requires the other party's public key in other to generate the symmetric secret. If we have multiple helpers / parties we need to specify which are creating the symmetric secret for as for each party that would be different symmetric secrets created.
