Struct ValidKeyAmalgamation 

pub struct ValidKeyAmalgamation<'a, P, R, R2>
where
    P: 'a + KeyParts,
    R: 'a + KeyRole,
    R2: Copy,
{ /* private fields */ }

A KeyAmalgamation plus a Policy and a reference time.

In the same way that a ValidComponentAmalgamation extends a ComponentAmalgamation, a ValidKeyAmalgamation extends a KeyAmalgamation: a ValidKeyAmalgamation combines a KeyAmalgamation, a Policy, and a reference time. This allows it to implement the ValidAmalgamation trait, which provides methods like ValidAmalgamation::binding_signature that require a Policy and a reference time. Although KeyAmalgamation could implement these methods by requiring that the caller explicitly pass them in, embedding them in the ValidKeyAmalgamation helps ensure that multipart operations, even those that span multiple functions, use the same Policy and reference time.

A ValidKeyAmalgamation can be obtained by transforming a KeyAmalgamation using ValidateAmalgamation::with_policy. A KeyAmalgamationIter can also be changed to yield ValidKeyAmalgamations.

A ValidKeyAmalgamation is guaranteed to come from a valid certificate, and have a valid and live binding signature at the specified reference time. Note: this only means that the binding signatures are live; it says nothing about whether the certificate or the Key is live and non-revoked. If you care about those things, you need to check them separately.

Examples:

Find all non-revoked, live, signing-capable keys:

use openpgp::policy::StandardPolicy;
use openpgp::types::RevocationStatus;

let p = &StandardPolicy::new();

// `with_policy` ensures that the certificate and any components
// that it returns have valid *binding signatures*.  But, we still
// need to check that the certificate and `Key` are not revoked,
// and live.
//
// Note: `ValidKeyAmalgamation::revocation_status`, etc. use the
// embedded policy and timestamp.  Even though we used `None` for
// the timestamp (i.e., now), they are guaranteed to use the same
// timestamp, because `with_policy` eagerly transforms it into
// the current time.
let cert = cert.with_policy(p, None)?;
if let RevocationStatus::Revoked(_revs) = cert.revocation_status() {
    // Revoked by the certificate holder.  (If we care about
    // designated revokers, then we need to check those
    // ourselves.)
} else if let Err(_err) = cert.alive() {
    // Certificate was created in the future or is expired.
} else {
    // `ValidCert::keys` returns `ValidKeyAmalgamation`s.
    for ka in cert.keys() {
        if let RevocationStatus::Revoked(_revs) = ka.revocation_status() {
            // Revoked by the key owner.  (If we care about
            // designated revokers, then we need to check those
            // ourselves.)
        } else if let Err(_err) = ka.alive() {
            // Key was created in the future or is expired.
        } else if ! ka.for_signing() {
            // We're looking for a signing-capable key, skip this one.
        } else {
            // Use it!
        }
    }
}

impl<'a, P, R, R2> ValidKeyAmalgamation<'a, P, R, R2>

where P: 'a + KeyParts, R: 'a + KeyRole, R2: Copy,

pub fn cert(&self) -> &'a Cert

Returns the component’s associated certificate.

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for k in cert.with_policy(p, None)?.keys() {
    // It's not only an identical `Cert`, it's the same one.
    assert!(std::ptr::eq(k.cert(), &cert));
}

pub fn binding_signature(&self) -> &'a Signature

Returns the valid amalgamation’s active binding signature.

The active binding signature is the most recent, non-revoked self-signature that is valid according to the policy and alive at time t (creation time <= t, t < expiry). If there are multiple such signatures then the signatures are ordered by their MPIs interpreted as byte strings.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

// Display information about each User ID's current active
// binding signature (the `time` parameter is `None`), if any.
for ua in cert.with_policy(p, None)?.userids() {
    eprintln!("{:?}", ua.binding_signature());
}

pub fn amalgamation(&self) -> &KeyAmalgamation<'a, P, R, R2>

Returns the valid amalgamation’s amalgamation.

Examples

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

// Get a key amalgamation.
let ka = cert.primary_key();

// Validate it, yielding a valid key amalgamation.
let vka = ka.with_policy(p, None)?;

// And here we get the amalgamation back.
let ka2 = vka.amalgamation();
assert_eq!(&ka, ka2);

pub fn bundle(&self) -> &'a ComponentBundle<Key<P, R>>

Returns this amalgamation’s bundle.

pub fn component(&self) -> &'a Key<P, R>

Returns this amalgamation’s component.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

// Display some information about any unknown components.
for k in cert.with_policy(p, None)?.keys() {
    eprintln!(" - {:?}", k.component());
}

pub fn key(&self) -> &'a Key<P, R>

Returns the KeyAmalgamation’s key.

pub fn self_signatures( &self, ) -> impl Iterator<Item = &'a Signature> + Send + Sync

Returns the component’s self-signatures.

The signatures are validated, and they are sorted by their creation time, most recent first.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for (i, ka) in cert.with_policy(p, None)?.keys().enumerate() {
    eprintln!("Key #{} ({}) has {:?} self signatures",
              i, ka.key().fingerprint(),
              ka.self_signatures().count());
}

pub fn certifications( &self, ) -> impl Iterator<Item = &'a Signature> + Send + Sync

Returns the component’s third-party certifications.

The signatures are not validated. They are sorted by their creation time, most recent first.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for k in cert.with_policy(p, None)?.keys() {
    eprintln!("Key {} has {:?} unverified, third-party certifications",
              k.key().fingerprint(),
              k.certifications().count());
}

pub fn self_revocations( &self, ) -> impl Iterator<Item = &'a Signature> + Send + Sync

Returns the component’s revocations that were issued by the certificate holder.

The revocations are validated, and they are sorted by their creation time, most recent first.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for k in cert.with_policy(p, None)?.keys() {
    eprintln!("Key {} has {:?} revocation certificates.",
              k.key().fingerprint(),
              k.self_revocations().count());
}

pub fn other_revocations( &self, ) -> impl Iterator<Item = &'a Signature> + Send + Sync

Returns the component’s revocations that were issued by other certificates.

The revocations are not validated. They are sorted by their creation time, most recent first.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for k in cert.with_policy(p, None)?.keys() {
    eprintln!("Key {} has {:?} unverified, third-party revocation certificates.",
              k.key().fingerprint(),
              k.other_revocations().count());
}

pub fn signatures(&self) -> impl Iterator<Item = &'a Signature> + Send + Sync

Returns all of the component’s signatures.

Only the self-signatures are validated. The signatures are sorted first by type, then by creation time. The self revocations come first, then the self signatures, then any certification approval key signatures, certifications, and third-party revocations coming last. This function may return additional types of signatures that could be associated to this component.

Examples

use openpgp::policy::StandardPolicy;
let p = &StandardPolicy::new();

for (i, ka) in cert.with_policy(p, None)?.keys().enumerate() {
    eprintln!("Key #{} ({}) has {:?} signatures",
              i, ka.key().fingerprint(),
              ka.signatures().count());
}

impl<'a, P, R, R2> ValidKeyAmalgamation<'a, P, R, R2>

where P: 'a + KeyParts, R: 'a + KeyRole, R2: Copy, Self: ValidAmalgamation<'a, Key<P, R>> + PrimaryKey<'a, P, R>,

pub fn alive(&self) -> Result<()>

Returns whether the key is alive as of the amalgamation’s reference time.

A ValidKeyAmalgamation is guaranteed to have a live binding signature. This is independent of whether the component is live.

If the certificate is not alive as of the reference time, no subkey can be alive.

This function considers both the binding signature and the direct key signature. Information in the binding signature takes precedence over the direct key signature. See Section 5.2.3.10 of RFC 9580.

For a definition of liveness, see the key_alive method.

Examples

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

let ka = cert.primary_key().with_policy(p, None)?;
if let Err(_err) = ka.alive() {
    // Not alive.
}

impl<'a, P, R, R2> ValidKeyAmalgamation<'a, P, R, R2>

where P: KeyParts, R: KeyRole, R2: Copy, Self: PrimaryKey<'a, P, R>,

pub fn primary_key_binding_signature(&self) -> Option<&Signature>

Returns the key’s primary key binding signature, if any.

The primary key binding signature is embedded inside a subkey binding signature. It is made by the subkey to indicate that it should be associated with the primary key. This prevents an attack in which an attacker creates a certificate, and associates the victim’s subkey with it thereby creating confusion about the certificate that issued a signature.

Not all keys have primary key binding signatures. First, primary keys don’t have them, because they don’t need them. Second, encrypt-capable subkeys don’t have them because they are not (usually) able to issue signatures.

Examples

let vc = cert.with_policy(P, None)?;

assert!(vc.primary_key().primary_key_binding_signature().is_none());

// A signing key has to have a primary key binding signature.
for ka in vc.keys().for_signing() {
    assert!(ka.primary_key_binding_signature().is_some());
}

// Encryption keys normally can't have a primary key binding
// signature, because they can't issue signatures.
for ka in vc.keys().for_transport_encryption() {
    assert!(ka.primary_key_binding_signature().is_none());
}

impl<'a, P> ValidKeyAmalgamation<'a, P, PrimaryRole, ()>

where P: 'a + KeyParts,

pub fn set_expiration_time( &self, primary_signer: &mut dyn Signer, expiration: Option<SystemTime>, ) -> Result<Vec<Signature>>

Creates signatures that cause the key to expire at the specified time.

This function creates new binding signatures that cause the key to expire at the specified time when integrated into the certificate. For the primary key, it is necessary to create a new self-signature for each non-revoked User ID, and to create a direct key signature. This is needed, because the primary User ID is first consulted when determining the primary key’s expiration time, and certificates can be distributed with a possibly empty subset of User IDs.

Setting a key’s expiry time means updating an existing binding signature—when looking up information, only one binding signature is normally considered, and we don’t want to drop the other information stored in the current binding signature. This function uses the binding signature determined by ValidKeyAmalgamation’s policy and reference time for this.

Examples

use std::time;
use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

let vc = cert.with_policy(p, None)?;

// Assert that the primary key is not expired.
assert!(vc.primary_key().alive().is_ok());

// Make the primary key expire in a week.
let t = time::SystemTime::now()
    + time::Duration::from_secs(7 * 24 * 60 * 60);

// We assume that the secret key material is available, and not
// password protected.
let mut signer = vc.primary_key()
    .key().clone().parts_into_secret()?.into_keypair()?;

let sigs = vc.primary_key().set_expiration_time(&mut signer, Some(t))?;
let cert = cert.insert_packets(sigs)?.0;

// The primary key isn't expired yet.
let vc = cert.with_policy(p, None)?;
assert!(vc.primary_key().alive().is_ok());

// But in two weeks, it will be...
let t = time::SystemTime::now()
    + time::Duration::from_secs(2 * 7 * 24 * 60 * 60);
let vc = cert.with_policy(p, t)?;
assert!(vc.primary_key().alive().is_err());

impl<'a, P> ValidKeyAmalgamation<'a, P, SubordinateRole, ()>

where P: 'a + KeyParts,

pub fn set_expiration_time( &self, primary_signer: &mut dyn Signer, subkey_signer: Option<&mut dyn Signer>, expiration: Option<SystemTime>, ) -> Result<Vec<Signature>>

Creates signatures that cause the key to expire at the specified time.

This function creates new binding signatures that cause the key to expire at the specified time when integrated into the certificate. For subkeys, a single Signature is returned.

Setting a key’s expiry time means updating an existing binding signature—when looking up information, only one binding signature is normally considered, and we don’t want to drop the other information stored in the current binding signature. This function uses the binding signature determined by ValidKeyAmalgamation’s policy and reference time for this.

When updating the expiration time of signing-capable subkeys, we need to create a new primary key binding signature. Therefore, we need a signer for the subkey. If subkey_signer is None, and this is a signing-capable subkey, this function fails with Error::InvalidArgument. Likewise, this function fails if subkey_signer is not None when updating the expiration of a non signing-capable subkey.

Examples

use std::time;
use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

let vc = cert.with_policy(p, None)?;

// Assert that the keys are not expired.
for ka in vc.keys() {

// We assume that the secret key material is available, and not
// password protected.

    .key().clone().parts_into_secret()?.into_keypair()?;
let mut signing_subkey_signer = vc.keys().for_signing().nth(0).unwrap()

where P: 'a + KeyParts,

pub fn set_expiration_time( &self, primary_signer: &mut dyn Signer, subkey_signer: Option<&mut dyn Signer>, expiration: Option<SystemTime>, ) -> Result<Vec<Signature>>

Creates signatures that cause the key to expire at the specified time.

This function creates new binding signatures that cause the key to expire at the specified time when integrated into the certificate. For subkeys, only a single Signature is returned.

impl<'a, P, R, R2> ValidKeyAmalgamation<'a, P, R, R2>

where P: 'a + KeyParts, R: 'a + KeyRole, R2: Copy, Self: ValidAmalgamation<'a, Key<P, R>> + ValidBindingSignature<'a, Key<P, R>>,

pub fn key_flags(&self) -> Option<KeyFlags>

Returns the key’s Key Flags.

A Key’s Key Flags holds information about the key. As of RFC 9580, this information is primarily concerned with the key’s capabilities (e.g., whether it may be used for signing). The other information that has been defined is: whether the key has been split using something like SSS, and whether the primary key material is held by multiple parties. In practice, the latter two flags are ignored.

As per Section 5.2.3.10 of RFC 9580, when looking for the Key Flags, the key’s binding signature is first consulted (in the case of the primary Key, this is the binding signature of the primary User ID). If the Key Flags subpacket is not present, then the direct key signature is consulted.

Since the key flags are taken from the active self signature, a key’s flags may change depending on the policy and the reference time.

To increase compatibility with early v4 certificates, if there is no key flags subpacket on the considered signatures, we infer the key flags from the key’s role and public key algorithm.

Examples

let ka = cert.primary_key();
println!("Primary Key's Key Flags: {:?}", ka.key_flags());

pub fn has_any_key_flag<F>(&self, flags: F) -> bool

where F: Borrow<KeyFlags>,

Returns whether the key has at least one of the specified key flags.

The key flags are looked up as described in ValidKeyAmalgamation::key_flags.

Examples

Finds keys that may be used for transport encryption (data in motion) or storage encryption (data at rest):

use openpgp::policy::StandardPolicy;
use openpgp::types::KeyFlags;

let p = &StandardPolicy::new();

for ka in cert.keys().with_policy(p, None) {
    if ka.has_any_key_flag(KeyFlags::empty()
       .set_storage_encryption()
       .set_transport_encryption())
    {
        // `ka` is encryption capable.
    }
}

pub fn for_certification(&self) -> bool

Returns whether the key is certification capable.

Note: Section 10.1 of RFC 9580 says that the primary key is certification capable independent of the Key Flags subpacket:

In a V4 key, the primary key MUST be a key capable of certification.

This function only reflects what is stored in the Key Flags packet; it does not implicitly set this flag. In practice, there are keys whose primary key’s Key Flags do not have the certification capable flag set. Some versions of netpgp, for instance, create keys like this. Sequoia’s higher-level functionality correctly handles these keys by always considering the primary key to be certification capable. Users of this interface should too.

The key flags are looked up as described in ValidKeyAmalgamation::key_flags.

Examples

Finds keys that are certification capable:

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

for ka in cert.keys().with_policy(p, None) {
    if ka.primary() || ka.for_certification() {
        // `ka` is certification capable.
    }
}

pub fn for_signing(&self) -> bool

Returns whether the key is signing capable.

The key flags are looked up as described in ValidKeyAmalgamation::key_flags.

Examples

Finds keys that are signing capable:

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

for ka in cert.keys().with_policy(p, None) {
    if ka.for_signing() {
        // `ka` is signing capable.
    }
}

pub fn for_authentication(&self) -> bool

Returns whether the key is authentication capable.

The key flags are looked up as described in ValidKeyAmalgamation::key_flags.

Examples

Finds keys that are authentication capable:

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

for ka in cert.keys().with_policy(p, None) {
    if ka.for_authentication() {
        // `ka` is authentication capable.
    }
}

pub fn for_storage_encryption(&self) -> bool

Returns whether the key is storage-encryption capable.

OpenPGP distinguishes two types of encryption keys: those for storage (data at rest) and those for transport (data in transit). Most OpenPGP implementations, however, don’t distinguish between them in practice. Instead, when they create a new encryption key, they just set both flags. Likewise, when encrypting a message, it is not typically possible to indicate the type of protection that is needed. Sequoia supports creating keys with only one of these flags set, and makes it easy to select the right type of key when encrypting messages.

The key flags are looked up as described in ValidKeyAmalgamation::key_flags.

Examples

Finds keys that are storage-encryption capable:

use openpgp::policy::StandardPolicy;

let p = &StandardPolicy::new();

for ka in cert.keys().with_policy(p, None) {
    if ka.for_storage_encryption() {
        // `ka` is storage-encryption capable.
    }
}

pub fn for_transport_encryption(&self) -> bool

Returns whether the key is transport-encryption capable.

    if ka.for_transport_encryption() {
        // `ka` is transport-encryption capable.
    }
}

pub fn key_validity_period(&self) -> Option<Duration>

Returns how long the key is live.

This returns how long the key is live relative to its creation time. Use ValidKeyAmalgamation::key_expiration_time to get the key’s absolute expiry time.

This function considers both the binding signature and the direct key signature. Information in the binding signature takes precedence over the direct key signature. See Section 5.2.3.10 of RFC 9580.

Examples

use std::time;
use std::convert::TryInto;
use openpgp::policy::StandardPolicy;
use openpgp::types::Timestamp;

let p = &StandardPolicy::new();

// OpenPGP Timestamps have a one-second resolution.  Since we
// want to round trip the time, round it down.
let now: Timestamp = time::SystemTime::now().try_into()?;
let now: time::SystemTime = now.try_into()?;

let a_week = time::Duration::from_secs(7 * 24 * 60 * 60);

let (cert, _) =
    CertBuilder::general_purpose(Some("alice@example.org"))
    .set_creation_time(now)
    .set_validity_period(a_week)
    .generate()?;

assert_eq!(cert.primary_key().with_policy(p, None)?.key_validity_period(),
           Some(a_week));

pub fn key_expiration_time(&self) -> Option<SystemTime>

Returns the key’s expiration time.

If this function returns None, the key does not expire.

This returns the key’s expiration time. Use ValidKeyAmalgamation::key_validity_period to get the duration of the key’s lifetime.
