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 following subset of CBOR primitives: text string, byte string, integer, bignum, floating point (16/32/64 bit), true, false, null, and tagged data (CBOR major type 6).
