Enum sequoia_openpgp::types::PublicKeyAlgorithm

#[non_exhaustive]
pub enum PublicKeyAlgorithm {
    RSAEncryptSign,
    RSAEncrypt,
    RSASign,
    ElGamalEncrypt,
    DSA,
    ECDH,
    ECDSA,
    ElGamalEncryptSign,
    EdDSA,
    Private(u8),
    Unknown(u8),
}

The OpenPGP public key algorithms as defined in Section 9.1 of RFC 4880, and Section 5 of RFC 6637.

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

Examples

use sequoia_openpgp as openpgp;
use openpgp::cert::prelude::*;
use openpgp::types::PublicKeyAlgorithm;

let (cert, _) = CertBuilder::new()
    .set_cipher_suite(CipherSuite::Cv25519)
    .generate()?;

assert_eq!(cert.primary_key().pk_algo(), PublicKeyAlgorithm::EdDSA);

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.

Implementations

impl PublicKeyAlgorithm

pub fn for_signing(&self) -> bool

Returns true if the algorithm can sign data.

Examples

use sequoia_openpgp as openpgp;
use openpgp::types::PublicKeyAlgorithm;

assert!(PublicKeyAlgorithm::EdDSA.for_signing());
assert!(PublicKeyAlgorithm::RSAEncryptSign.for_signing());
assert!(!PublicKeyAlgorithm::ElGamalEncrypt.for_signing());

pub fn for_encryption(&self) -> bool

Returns true if the algorithm can encrypt data.

Examples

use sequoia_openpgp as openpgp;
use openpgp::types::PublicKeyAlgorithm;

assert!(!PublicKeyAlgorithm::EdDSA.for_encryption());
assert!(PublicKeyAlgorithm::RSAEncryptSign.for_encryption());
assert!(PublicKeyAlgorithm::ElGamalEncrypt.for_encryption());

pub fn is_supported(&self) -> bool

Returns whether this algorithm is supported.

Examples

use sequoia_openpgp as openpgp;
use openpgp::types::PublicKeyAlgorithm;

assert!(PublicKeyAlgorithm::EdDSA.is_supported());
assert!(PublicKeyAlgorithm::RSAEncryptSign.is_supported());
assert!(!PublicKeyAlgorithm::ElGamalEncrypt.is_supported());
assert!(!PublicKeyAlgorithm::Private(101).is_supported());
