Implement COSE Signing, IETF RFC 8152, section 4
Minimum Viable Product - Single Signer
- Read and expose metadata for tagged and untagged COSE_Sign1 messages
- Validate signature with both embedded and detached content, from both formats.
- ECDsa
- RSASSA-PSS (from IETF RFC 8230)
- Create new embedded- and detached- content signature.
This minimum viable product can be shipped as a NuGet package for verification by early adopters before continuing into the multiple signers scope.
Things that won't be covered on the MVP:
- Validation of Critical headers
- A model to interact with Counter Signatures headers.
