[][src]Type Definition sequoia_openpgp::cert::amalgamation::UserIDAmalgamation

type UserIDAmalgamation<'a> = ComponentAmalgamation<'a, UserID>;

A User ID and its associated data.

A specialized version of ComponentAmalgamation.

Implementations

impl<'a> UserIDAmalgamation<'a>[src]

pub fn userid(&self) -> &'a UserID[src]

Returns a reference to the User ID.

Note: although ComponentAmalgamation<UserID> derefs to a &UserID (via &ComponentBundle), this method provides a more accurate lifetime, which is helpful when returning the reference from a function. See the module's documentation for more details.

pub fn attest_certifications<C, S>(
    &self,
    policy: &dyn Policy,
    primary_signer: &mut dyn Signer,
    certifications: C
) -> Result<Vec<Signature>> where
    C: IntoIterator<Item = S>,
    S: Borrow<Signature>, 
[src]

Attests to third-party certifications.

This feature is experimental.

Allows the certificate owner to attest to third party certifications. See Section 5.2.3.30 of RFC 4880bis for details. This can be used to address certificate flooding concerns.

A policy is needed, because the expiration is updated by updating the current binding signatures.

Examples

let (alice, _) = CertBuilder::new()
    .add_userid("alice@example.org")
    .generate()?;
let mut alice_signer =
    alice.primary_key().key().clone().parts_into_secret()?
    .into_keypair()?;

let (bob, _) = CertBuilder::new()
    .add_userid("bob@example.org")
    .generate()?;
let mut bob_signer =
    bob.primary_key().key().clone().parts_into_secret()?
    .into_keypair()?;
let bob_pristine = bob.clone();

// Have Alice certify the binding between "bob@example.org" and
// Bob's key.
let alice_certifies_bob
    = bob.userids().next().unwrap().userid().bind(
        &mut alice_signer, &bob,
        SignatureBuilder::new(SignatureType::GenericCertification))?;
let bob = bob.insert_packets(vec![alice_certifies_bob.clone()])?;

// Have Bob attest that certification.
let bobs_uid = bob.userids().next().unwrap();
let attestations =
    bobs_uid.attest_certifications(
        policy,
        &mut bob_signer,
        bobs_uid.certifications())?;
let bob = bob.insert_packets(attestations)?;

assert_eq!(bob.bad_signatures().count(), 0);
assert_eq!(bob.userids().next().unwrap().certifications().next(),
           Some(&alice_certifies_bob));
