 The meaning of an OpenPGP signature depends significantly on its issuer. Self-signatures and third-party signatures, even when of the same [signature type](https://www.ietf.org/archive/id/draft-ietf-openpgp-crypto-refresh-12.html#name-signature-types), serve distinct functions. For example:
 
 - Certifying self-signatures (type IDs `0x10` - `0x13`) bind a User ID to a certificate.

+- Third-party signatures of the same type IDs endorse the authenticity of a User ID.
