Enum sequoia_openpgp::types::AEADAlgorithm

#[non_exhaustive]
pub enum AEADAlgorithm {
    EAX,
    OCB,
    Private(u8),
    Unknown(u8),
}

The AEAD algorithms as defined in Section 9.6 of RFC 4880bis.

The values can be converted into and from their corresponding values of the serialized format.

Use AEADAlgorithm::from to translate a numeric value to a symbolic one.

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

This feature is experimental.

Examples

Use AEADAlgorithm to set the preferred AEAD algorithms on a signature:

use sequoia_openpgp as openpgp;
use openpgp::packet::signature::SignatureBuilder;
use openpgp::types::{Features, HashAlgorithm, AEADAlgorithm, SignatureType};

let features = Features::empty().set_aead();
let mut builder = SignatureBuilder::new(SignatureType::DirectKey)
    .set_features(features)?
    .set_preferred_aead_algorithms(vec![
        AEADAlgorithm::EAX,
    ])?;

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.

EAX

EAX mode.

OCB

OCB mode.

Private(u8)

Private algorithm identifier.

Unknown(u8)

Unknown algorithm identifier.

Implementations

impl AEADAlgorithm

pub fn digest_size(&self) -> Result<usize>

Returns the digest size of the AEAD algorithm.

pub fn iv_size(&self) -> Result<usize>

Returns the initialization vector size of the AEAD algorithm.

impl AEADAlgorithm

pub fn is_supported(&self) -> bool

Returns whether this algorithm is supported.

Examples

use sequoia_openpgp as openpgp;
use openpgp::types::AEADAlgorithm;

assert!(! AEADAlgorithm::Private(100).is_supported());

Trait Implementations

impl Clone for AEADAlgorithm

fn clone(&self) -> AEADAlgorithm

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AEADAlgorithm

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

Formats the value using the given formatter.

impl Display for AEADAlgorithm

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

Formats the value using the given formatter.

impl From<AEADAlgorithm> for u8

fn from(s: AEADAlgorithm) -> u8

Converts to this type from the input type.

impl From<u8> for AEADAlgorithm

fn from(u: u8) -> Self

Converts to this type from the input type.

impl Hash for AEADAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AEADAlgorithm

fn cmp(&self, other: &AEADAlgorithm) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<AEADAlgorithm> for AEADAlgorithm

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

This method tests for self and other values to be equal, and is used by ==.

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
