Expand description

Holds an arbitrary, well-structured subpacket.

The SubpacketValue enum holds a Subpacket’s value. The values are well structured in the sense that they have been parsed into Sequoia’s native data types rather than just holding the raw byte vector. For instance, the Issuer variant holds a KeyID.

Note: This enum cannot be exhaustively matched to allow future extensions.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`Unknown`

Fields

tag: SubpacketTag

The unknown subpacket’s tag.

body: Vec<u8>

The unknown subpacket’s uninterpreted body.

An unknown subpacket.

`SignatureCreationTime(Timestamp)`

The time the signature was made.

See Section 5.2.3.4 of RFC 4880 for details.

`SignatureExpirationTime(Duration)`

The validity period of the signature.

The validity is relative to the time stored in the signature’s Signature Creation Time subpacket.

See Section 5.2.3.10 of RFC 4880 for details.

`ExportableCertification(bool)`

Whether a signature should be published.

See Section 5.2.3.11 of RFC 4880 for details.

`TrustSignature`

Fields

level: u8

Trust level, or depth.

Level 0 has the same meaning as an ordinary validity signature. Level 1 means that the signed key is asserted to be a valid trusted introducer, with the 2nd octet of the body specifying the degree of trust. Level 2 means that the signed key is asserted to be trusted to issue level 1 trust signatures, i.e., that it is a “meta introducer”.

trust: u8

Trust amount.

This is interpreted such that values less than 120 indicate partial trust and values of 120 or greater indicate complete trust. Implementations SHOULD emit values of 60 for partial trust and 120 for complete trust.

Signer asserts that the key is not only valid but also trustworthy at the specified level.

See Section 5.2.3.13 of RFC 4880 for details.

`RegularExpression(Vec<u8>)`

Used in conjunction with Trust Signature packets (of level > 0) to limit the scope of trust that is extended.

See Section 5.2.3.14 of RFC 4880 for details.

Note: The RFC requires that the serialized form includes a trailing NUL byte. When Sequoia parses the regular expression subpacket, it strips the trailing NUL. (If it doesn’t include a NUL, then parsing fails.) Likewise, when it serializes a regular expression subpacket, it unconditionally adds a NUL.

`Revocable(bool)`

Whether a signature can later be revoked.

See Section 5.2.3.12 of RFC 4880 for details.

`KeyExpirationTime(Duration)`

The validity period of the key.

The validity period is relative to the key’s (not the signature’s) creation time.

See Section 5.2.3.6 of RFC 4880 for details.

`PreferredSymmetricAlgorithms(Vec<SymmetricAlgorithm>)`

The Symmetric algorithms that the certificate holder prefers.

See Section 5.2.3.7 of RFC 4880 for details.

`RevocationKey(RevocationKey)`

Authorizes the specified key to issue revocation signatures for this certificate.

See Section 5.2.3.15 of RFC 4880 for details.

`Issuer(KeyID)`

The OpenPGP Key ID of the key issuing the signature.

See Section 5.2.3.5 of RFC 4880 for details.

`NotationData(NotationData)`

A “notation” on the signature.

See Section 5.2.3.16 of RFC 4880 for details.

`PreferredHashAlgorithms(Vec<HashAlgorithm>)`

The Hash algorithms that the certificate holder prefers.

See Section 5.2.3.8 of RFC 4880 for details.

`PreferredCompressionAlgorithms(Vec<CompressionAlgorithm>)`

The compression algorithms that the certificate holder prefers.

See Section 5.2.3.9 of RFC 4880 for details.

`KeyServerPreferences(KeyServerPreferences)`

A list of flags that indicate preferences that the certificate holder has about how the key is handled by a key server.

See Section 5.2.3.17 of RFC 4880 for details.

`PreferredKeyServer(Vec<u8>)`

The URI of a key server where the certificate holder keeps their certificate up to date.

See Section 5.2.3.18 of RFC 4880 for details.

`PrimaryUserID(bool)`

A flag in a User ID’s self-signature that states whether this User ID is the primary User ID for this certificate.

See Section 5.2.3.19 of RFC 4880 for details.

`PolicyURI(Vec<u8>)`

The URI of a document that describes the policy under which the signature was issued.

See Section 5.2.3.20 of RFC 4880 for details.

`KeyFlags(KeyFlags)`

A list of flags that hold information about a key.

See Section 5.2.3.21 of RFC 4880 for details.

`SignersUserID(Vec<u8>)`

The User ID that is responsible for the signature.

See Section 5.2.3.22 of RFC 4880 for details.

`ReasonForRevocation`

Fields

code: ReasonForRevocation

Machine-readable reason for revocation.

reason: Vec<u8>

Human-readable reason for revocation.

The reason for a revocation, used in key revocations and certification revocation signatures.

See Section 5.2.3.23 of RFC 4880 for details.

`Features(Features)`

The OpenPGP features a user’s implementation supports.

See Section 5.2.3.24 of RFC 4880 for details.

`SignatureTarget`

Fields

pk_algo: PublicKeyAlgorithm

Public-key algorithm of the target signature.

hash_algo: HashAlgorithm

Hash algorithm of the target signature.

digest: Vec<u8>

Hash digest of the target signature.

A signature to which this signature refers.

See Section 5.2.3.25 of RFC 4880 for details.

`EmbeddedSignature(Signature)`

A complete Signature packet body.

This is used to store a backsig in a subkey binding signature.

See Section 5.2.3.26 of RFC 4880 for details.

`IssuerFingerprint(Fingerprint)`

The Fingerprint of the key that issued the signature (proposed).

See Section 5.2.3.28 of RFC 4880bis for details.

`PreferredAEADAlgorithms(Vec<AEADAlgorithm>)`

👎 Deprecated

The AEAD algorithms that the certificate holder prefers (proposed).

See Section 5.2.3.8 of RFC 4880bis for details.

`IntendedRecipient(Fingerprint)`

Who the signed message was intended for (proposed).

See Section 5.2.3.29 of RFC 4880bis for details.

`AttestedCertifications(Vec<Box<[u8]>>)`

The Attested Certifications subpacket (proposed).

Allows the certificate holder to attest to third party certifications, allowing them to be distributed with the certificate. This can be used to address certificate flooding concerns.
