Struct OnePassSignature

pub struct OnePassSignature {
    pub packet_version: Version,
    pub typ: SignatureType,
    pub hash_algorithm: HashAlgorithm,
    pub pub_algorithm: PublicKeyAlgorithm,
    pub last: u8,
    pub version_specific: OpsVersionSpecific,
}

One-Pass Signature Packet https://www.rfc-editor.org/rfc/rfc9580.html#name-one-pass-signature-packet-t

A One-Pass Signature Packet acts as a companion to a Signature Packet. In modern OpenPGP messages, Ops and Signatures occur in pairs, bracketing the message payload.

The Ops packet contains all the information that a recipient needs to calculate the hash digest for the signature. This enables the recipient to process the message in “one pass”, calculating the hash digest based on the Ops Packet (which occurs before the message payload), and validating the cryptographic signature in the Signature Packet (which occurs after the message payload) after hashing is completed.

Fields

packet_version: Version

typ: SignatureType

hash_algorithm: HashAlgorithm

pub_algorithm: PublicKeyAlgorithm

last: u8

version_specific: OpsVersionSpecific

Implementations

impl OnePassSignature

pub fn version(&self) -> u8

impl OnePassSignature

pub fn from_slice(packet_version: Version, input: &[u8]) -> Result<Self>

Parses a OnePassSignature packet from the given slice.

pub fn v3( typ: SignatureType, hash_algorithm: HashAlgorithm, pub_algorithm: PublicKeyAlgorithm, key_id: KeyId, ) -> Self

Constructor for a v3 one pass signature packet.

RFC 4880-era OpenPGP uses v3 one pass signature packets (NOTE: there is no v4 OPS)

“When generating a one-pass signature, the OPS packet version MUST correspond to the version of the associated Signature packet, except for the historical accident that version 4 keys use a version 3 One-Pass Signature packet (there is no version 4 OPS).”

https://www.rfc-editor.org/rfc/rfc9580.html#name-one-pass-signature-packet-t

pub fn v6( typ: SignatureType, hash_algorithm: HashAlgorithm, pub_algorithm: PublicKeyAlgorithm, salt: Vec<u8>, fingerprint: [u8; 32], ) -> Self

Constructor for a v6 one pass signature packet.

Version 6 OpenPGP signatures must be combined with v6 one pass signature packets.

Trait Implementations

impl Clone for OnePassSignature

fn clone(&self) -> OnePassSignature

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OnePassSignature

fn fmt(&self, __derive_more_f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<OnePassSignature> for Packet

fn from(other: OnePassSignature) -> Packet

Converts to this type from the input type.

impl PacketTrait for OnePassSignature

fn packet_version(&self) -> Version

fn tag(&self) -> Tag

impl PartialEq for OnePassSignature

fn eq(&self, other: &OnePassSignature) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for OnePassSignature

fn to_writer<W: Write>(&self, writer: &mut W) -> Result<()>

fn to_bytes(&self) -> Result<Vec<u8>>

impl TryFrom<Packet> for OnePassSignature

type Error = Error

The type returned in the event of a conversion error.

fn try_from(other: Packet) -> Result<OnePassSignature, Self::Error>

Performs the conversion.

impl Eq for OnePassSignature

impl StructuralPartialEq for OnePassSignature
