Enhancement request: version of signer for old-school algos (i.e RSA + NIST curves)

[udf2457]

Thanks for your work on tkey.

It would be nice to see a version of signer that supports old-school algos such as RSA and the NIST p-curves.

I know Ed2559 is awesome and all that, but unfortunately there are applications that don't yet support Ed25519. For example CNCF project SPIFFE/SPIRE only supports EC or RSA key types. Using tkey in conjunction with SPIFFE/SPIRE could be a very interesting use-case for tkey.

Sadly whilst I am a proficient Go programmer, my C knowledge is non existent. And so sadly because tkey apps need to be written in C I would be too worried about messing up C crypto myself !

Good idea! We need to look at suitable libraries to use and exact type of signing to support.
