Module cose 

COSE_Sign1 — CBOR-encoded signature wrapper (RFC 8152).

Wraps a single signature in the COSE_Sign1 structure:

COSE_Sign1 = [
    protected : bstr .cbor {1: algorithm},
    unprotected : {},
    payload : bstr,
    signature : bstr
]

Used in IoT and edge computing for compact binary signatures. The implementation uses a minimal CBOR encoder for the specific COSE_Sign1 structure — no external CBOR dependency.
