Expand description

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)

This enum is marked as 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.

RSAEncryptSign

RSA (Encrypt or Sign)

RSAEncrypt

👎 Deprecated:

Use PublicKeyAlgorithm::RSAEncryptSign.

RSA Encrypt-Only, deprecated in RFC 4880.

RSASign

👎 Deprecated:

Use PublicKeyAlgorithm::RSAEncryptSign.

RSA Sign-Only, deprecated in RFC 4880.

ElGamalEncrypt

ElGamal (Encrypt-Only)

DSA

DSA (Digital Signature Algorithm)

ECDH

Elliptic curve DH

ECDSA

Elliptic curve DSA

ElGamalEncryptSign

👎 Deprecated:

If you really must, use PublicKeyAlgorithm::ElGamalEncrypt.

ElGamal (Encrypt or Sign), deprecated in RFC 4880.

EdDSA

“Twisted” Edwards curve DSA

Private(u8)

Private algorithm identifier.

Unknown(u8)

Unknown algorithm identifier.

Implementations

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());

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());

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::Private(101).is_supported());

Returns an iterator over all valid variants.

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

Trait Implementations

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Formats the public key algorithm name.

There are two ways the public key algorithm name can be formatted. By default the short name is used. The alternate format uses the full public key algorithm name.

Examples

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

// default, short format
assert_eq!("ECDH", format!("{}", PublicKeyAlgorithm::ECDH));

// alternate, long format
assert_eq!("ECDH public key algorithm", format!("{:#}", PublicKeyAlgorithm::ECDH));
