Struct sequoia_openpgp::packet::MDC

source ·
pub struct MDC { /* private fields */ }
Expand description

Holds an MDC packet.

A modification detection code packet. This packet appears after a SEIP packet. See Section 5.14 of RFC 4880 for details.

§A note on equality

Two MDC packets are considered equal if their serialized form is equal. This excludes the computed digest.

Implementations§
