Struct sequoia_openpgp::packet::signature::subpacket::NotationData

pub struct NotationData { /* private fields */ }
Expand description

Payload of a Notation Data subpacket.

The Notation Data subpacket provides a mechanism for a message’s signer to insert nearly arbitrary data into the signature. Because notations can be marked as critical, it is possible to add security relevant notations, which the receiving OpenPGP implementation will respect (in the sense that an implementation will reject signatures that include unknown, critical notations), even if they don’t understand the notations themselves.

It is possible to control how Sequoia’s higher-level functionality handles unknown, critical notations using a Policy object. Depending on the degree of control required, it may be sufficient to customize a StandardPolicy object using, for instance, the StandardPolicy::good_critical_notations method.

Notation names are human-readable UTF-8 strings. There are two namespaces: The user namespace and the IETF namespace. Names in the user namespace have the form name@example.org and are managed by the owner of the domain. Names in the IETF namespace may not contain an @ and are managed by IANA. See Section 5.2.3.16 of RFC 4880 for details.
