Expand description

The OpenPGP packet tags as defined in Section 4.3 of RFC 4880.

The values correspond to the serialized format.

Variants

One-Pass Signature Packet.

`SecretKey`

Secret-Key Packet.

`PublicKey`

Public-Key Packet.

`SecretSubkey`

Secret-Subkey Packet.

`CompressedData`

Compressed Data Packet.

`SED`

Symmetrically Encrypted Data Packet.

`Marker`

Marker Packet (Obsolete Literal Packet).

`Literal`

Literal Data Packet.

`Trust`

Trust Packet.

`UserID`

User ID Packet.

`PublicSubkey`

Public-Subkey Packet.

`UserAttribute`

User Attribute Packet.

`SEIP`

Sym. Encrypted and Integrity Protected Data Packet.

`MDC`

Modification Detection Code Packet.

`Private(u8)`

Experimental packets.

Implementations

impl Tag

pub fn valid_start_of_message(&self) -> bool

Returns whether the Tag can be at the start of a valid message.

Certs can start with PublicKey, TSKs with a SecretKey.

Messages start with a OnePassSig, Signature (old style non-one pass signatures), PKESK, SKESK, CompressedData, or Literal.

Signatures can standalone either as a detached signature, a third-party certification, or a revocation certificate.

pub fn variants() -> impl Iterator<Item = Tag>

Returns an iterator over all valid variants.

Returns an iterator over all known variants. This does not include the Tag::Reserved, Tag::Private, or Tag::Unknown variants.
