CBOR Signature Format (CSF)

This service permits testing and debugging CBOR [RFC 8949] based systems using digital signatures. Unlike COSE [RFC 8152], CSF utilizes Deterministic Encoding enabling signatures to become a part of the application data, rather than embedding such data in signatures. For detailed technical information click on the CSF logotype.

This implementation supports the [CBOR::Core] primitives (tstr, bstr, int, bigint, float, bool, null, tagged data, and simple values).
