Enumeration of packet types.

The different OpenPGP packets are detailed in Section 5 of RFC 4880.

The Unknown packet allows Sequoia to deal with packets that it doesn’t understand. It is basically a binary blob that includes the packet’s tag. See the module-level documentation for details.

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

A note on equality

We define equality on Packet as the equality of the serialized form of their packet bodies as defined by RFC 4880. That is, two packets are considered equal if and only if their serialized forms are equal, modulo the OpenPGP framing (CTB and length style, potential partial body encoding).

Variants (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(Unknown)

Unknown packet.

Signature(Signature)

Signature packet.

OnePassSig(OnePassSig)

One pass signature packet.

PublicKey(Key<PublicParts, PrimaryRole>)

Public key packet.

PublicSubkey(Key<PublicParts, SubordinateRole>)

Public subkey packet.

SecretKey(Key<SecretParts, PrimaryRole>)

Public/Secret key pair.

SecretSubkey(Key<SecretParts, SubordinateRole>)

Public/Secret subkey pair.

Marker(Marker)

Marker packet.

Trust(Trust)

Trust packet.

UserID(UserID)

User ID packet.

UserAttribute(UserAttribute)

User attribute packet.

Literal(Literal)

Literal data packet.

CompressedData(CompressedData)

Compressed literal data packet.

PKESK(PKESK)

Public key encrypted data packet.

SKESK(SKESK)

Symmetric key encrypted data packet.

SEIP(SEIP)

Symmetric key encrypted, integrity protected data packet.

MDC(MDC)

👎Deprecated

Modification detection code packet.

AED(AED)

AEAD Encrypted Data Packet.

Implementations

impl Packet

pub fn tag(&self) -> Tag

Returns the Packet's corresponding OpenPGP tag.

Tags are explained in Section 4.3 of RFC 4880.

pub fn kind(&self) -> Option<Tag>

Returns the parsed Packet's corresponding OpenPGP tag.

Returns the packets tag, but only if it was successfully parsed into the corresponding packet type. If e.g. a Signature Packet uses some unsupported methods, it is parsed into an Packet::Unknown. tag() returns Tag::Signature, whereas kind() returns None.

pub fn version(&self) -> Option<u8>

Returns the Packet's version, if the packet is versioned and recognized.

If the packet is not versioned, or we couldn’t parse the packet, this function returns None.

pub fn normalized_hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes most everything into state.

This is an alternate implementation of Hash, which does not hash:

• The unhashed subpacket area of Signature packets.
• Secret key material.

Unlike Signature::normalize, this method ignores authenticated packets in the unhashed subpacket area.
