Struct sequoia_openpgp::cert::amalgamation::key::ValidKeyAmalgamation

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

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!
        }
    }
}

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 5.2.3.3 of RFC 4880.

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.
}

Examples

use openpgp::policy::StandardPolicy;

// And here we get it back:
let ka = vka.into_key_amalgamation();

    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)?;

// 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

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 an non signing-capable subkey.

    R2: Copy,
    Self: ValidAmalgamation<'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 4880, 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 5.2.3.3 of RFC 4880, 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.

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 12.1 of RFC 4880 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.
    }
}

        // `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 5.2.3.3 of RFC 4880.

Examples

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

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.

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 5.2.3.3 of RFC 4880.

let now: time::SystemTime = now.try_into()?;
let a_week = time::Duration::from_secs(7 * 24 * 60 * 60);
let a_week_later = now + a_week;

pub fn parts_as_unspecified(
    &'a self
) -> &ErasedKeyAmalgamation<'a, UnspecifiedParts>

Changes the key’s parts tag to UnspecifiedParts.

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

Returns the KeyAmalgamation’s ComponentAmalgamation.

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

Returns the KeyAmalgamation’s key.

Normally, a type implementing KeyAmalgamation eventually derefs to a Key, however, this method provides a more accurate lifetime. See the documentation for ComponentAmalgamation::component for an explanation.

Methods from Deref<Target = ComponentAmalgamation<'a, Key<P, R>>>

pub fn parts_as_public(
    &'a self
) -> &'a ComponentAmalgamation<'a, Key<PublicParts, R>>

Changes the key’s parts tag to PublicParts.

pub fn parts_as_secret(
    &'a self
) -> Result<&'a ComponentAmalgamation<'a, Key<SecretParts, R>>>

Changes the key’s parts tag to SecretParts.

pub fn parts_as_unspecified(
    &'a self
) -> &ComponentAmalgamation<'a, Key<UnspecifiedParts, R>>

Changes the key’s parts tag to UnspecifiedParts.

pub fn role_as_primary(
    &'a self
) -> &'a ComponentAmalgamation<'a, Key<P, PrimaryRole>>

Changes the key’s role tag to PrimaryRole.

pub fn role_as_subordinate(
    &'a self
) -> &'a ComponentAmalgamation<'a, Key<P, SubordinateRole>>

Changes the key’s role tag to SubordinateRole.

pub fn role_as_unspecified(
    &'a self
) -> &'a ComponentAmalgamation<'a, Key<P, UnspecifiedRole>>

Changes the key’s role tag to UnspecifiedRole.

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

Returns the component’s associated certificate.

for u in cert.userids() {
    // It's not only an identical `Cert`, it's the same one.
    assert!(std::ptr::eq(u.cert(), &cert));
}

pub fn bundle(&self) -> &'a ComponentBundle<C>

Returns this amalgamation’s bundle.

Note: although ComponentAmalgamation derefs to a &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.

Examples

use openpgp::cert::prelude::*;
use openpgp::packet::prelude::*;

cert.userids()
    .map(|ua| {
        // The following doesn't work:
        //
        //   let b: &ComponentBundle<_> = &ua; b
        //
        // Because ua's lifetime is this closure and autoderef
        // assigns `b` the same lifetime as `ua`.  `bundle()`,
        // however, returns a reference whose lifetime is that
        // of `cert`.
        ua.bundle()
    })
    .collect::<Vec<&ComponentBundle<_>>>();

pub fn component(&self) -> &'a C

Returns this amalgamation’s component.

Note: although ComponentAmalgamation derefs to a &Component (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 self_signatures(
    &self
) -> impl Iterator<Item = &'a Signature> + Send + Sync

The component’s self-signatures.

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

The component’s third-party certifications.

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

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

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

The component’s revocations that were issued by other certificates.

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

Returns all of the component’s signatures.

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

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 user_attribute(&self) -> &'a UserAttribute

Returns a reference to the User Attribute.

Note: although ComponentAmalgamation<UserAttribute> derefs to a &UserAttribute (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.

Returns a reference to the bundle’s component.

Examples

// Display some information about any unknown components.
for u in cert.unknowns() {
    eprintln!(" - {:?}", u.component());
}

pub fn binding_signature<T>(
    &self,
    policy: &dyn Policy,
    t: T
) -> Result<&Signature> where
    T: Into<Option<SystemTime>>, 

Returns the active binding signature at time t.

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.userids() {
    eprintln!("{:?}", ua.binding_signature(p, None));
}

pub fn self_signatures(&self) -> &[Signature]

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.keys().enumerate() {
    eprintln!("Key #{} ({}) has {:?} self signatures",
              i, ka.fingerprint(),
              ka.bundle().self_signatures().len());
}

pub fn certifications(&self) -> &[Signature]

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 ua in cert.userids() {
    eprintln!("User ID {} has {:?} unverified, third-party certifications",
              String::from_utf8_lossy(ua.userid().value()),
              ua.bundle().certifications().len());
}

pub fn self_revocations(&self) -> &[Signature]

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 u in cert.userids() {
    eprintln!("User ID {} has {:?} revocation certificates.",
              String::from_utf8_lossy(u.userid().value()),
              u.bundle().self_revocations().len());
}

pub fn other_revocations(&self) -> &[Signature]

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 u in cert.userids() {
    eprintln!("User ID {} has {:?} unverified, third-party revocation certificates.",
              String::from_utf8_lossy(u.userid().value()),
              u.bundle().other_revocations().len());
}

pub fn signatures(&self) -> impl Iterator<Item = &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, 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.keys().enumerate() {
    eprintln!("Key #{} ({}) has {:?} signatures",
              i, ka.fingerprint(),
              ka.signatures().count());
}

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

Returns a reference to the key.

This is just a type-specific alias for ComponentBundle::component.

Examples

// Display some information about the keys.
for ka in cert.keys() {
    eprintln!(" - {:?}", ka.key());
}

pub fn revocation_status<T>(
    &self,
    policy: &dyn Policy,
    t: T
) -> RevocationStatus<'_> where
    T: Into<Option<SystemTime>>, 

Returns the subkey’s revocation status at time t.

A subkey is revoked at time t if:

• There is a live revocation at time t that is newer than all live self signatures at time t, or

• There is a hard revocation (even if it is not live at time t, and even if there is a newer self-signature).

Note: Certs and subkeys have different criteria from User IDs and User Attributes.

Note: this only returns whether this subkey is revoked; it does not imply anything about the Cert or other components.

Examples

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

// Display the subkeys' revocation status.
for ka in cert.keys().subkeys() {
    eprintln!(" Revocation status of {}: {:?}",
              ka.fingerprint(), ka.revocation_status(p, None));
}

pub fn userid(&self) -> &UserID

Returns a reference to the User ID.

This is just a type-specific alias for ComponentBundle::component.

Examples

// Display some information about the User IDs.
for ua in cert.userids() {
    eprintln!(" - {:?}", ua.userid());
}

pub fn revocation_status<T>(
    &self,
    policy: &dyn Policy,
    t: T
) -> RevocationStatus<'_> where
    T: Into<Option<SystemTime>>, 

Returns the User ID’s revocation status at time t.

A User ID is revoked at time t if:

• There is a live revocation at time t that is newer than all live self signatures at time t.

Note: Certs and subkeys have different criteria from User IDs and User Attributes.

Note: this only returns whether this User ID is revoked; it does not imply anything about the Cert or other components.

Examples

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

// Display the User IDs' revocation status.
for ua in cert.userids() {
    eprintln!(" Revocation status of {}: {:?}",
              String::from_utf8_lossy(ua.userid().value()),
              ua.revocation_status(p, None));
}

pub fn user_attribute(&self) -> &UserAttribute

Returns a reference to the User Attribute.

This is just a type-specific alias for ComponentBundle::component.

Examples

// Display some information about the User Attributes
for ua in cert.user_attributes() {
    eprintln!(" - {:?}", ua.user_attribute());
}

pub fn revocation_status<T>(
    &self,
    policy: &dyn Policy,
    t: T
) -> RevocationStatus<'_> where
    T: Into<Option<SystemTime>>, 

Returns the User Attribute’s revocation status at time t.

A User Attribute is revoked at time t if:

• There is a live revocation at time t that is newer than all live self signatures at time t.

Note: Certs and subkeys have different criteria from User IDs and User Attributes.

Note: this only returns whether this User Attribute is revoked; it does not imply anything about the Cert or other components.

Examples

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

// Display the User Attributes' revocation status.
for (i, ua) in cert.user_attributes().enumerate() {
    eprintln!(" Revocation status of User Attribute #{}: {:?}",
              i, ua.revocation_status(p, None));
}

pub fn unknown(&self) -> &Unknown

Returns a reference to the unknown component.

This is just a type-specific alias for ComponentBundle::component.

Examples

// Display some information about the User Attributes
for u in cert.unknowns() {
    eprintln!(" - {:?}", u.unknown());
}
