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
