Common Companion Terms

gmeow:CryptographicSignature

Usage Advice

Use when

• Use when a signature is specifically an S/MIME signature (RFC 8551) bound to an X.509 certificate — the scheme-typed specialization of gmeow:CryptographicSignature.

Avoid when

• Avoid for an OpenPGP signature (use gmeow:PGPSignature) and for a scheme-agnostic case (use the parent gmeow:CryptographicSignature); the type fixes the X.509/S-MIME scheme.

How to use

• Type the signature gmeow:SMIMESignature and bind gmeow:signingKey to a key whose gmeow:keyScheme is gmeow:keySchemeX509; signedBy, algorithm, and verification status come from the parent.

Examples

• ex:sig2 a gmeow:SMIMESignature; gmeow:signingKey ex:x509Key.
