Enum Algorithm 

#[non_exhaustive]
pub enum Algorithm {
    Rsa,
    ElGamal,
    Dsa,
    Ecdh,
    Ecdsa,
    Eddsa,
    Sm2,
}

Public-key algorithm. Maps to the RNP_ALGNAME_* string constants in rnp.h.

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.

Rsa

"RSA". Used for primary or subkey; supports sign + encrypt (legacy).

ElGamal

"ELGAMAL". Subkey only, encryption.

Dsa

"DSA". Primary only, signing.

Ecdh

"ECDH". Subkey only, encryption.

Ecdsa

"ECDSA". Primary or subkey, signing.

Eddsa

"EDDSA". Primary or subkey, signing (Ed25519 curve).

Sm2

"SM2". Primary or subkey, sign + encrypt.

Implementations

impl Algorithm

pub fn as_str(self) -> &'static str

pub fn is_signature(self) -> bool

Whether this algorithm can produce signatures. Maps to OpenPGP’s “signing-capable” public-key algorithms (DSA, ECDSA, EdDSA, SM2, RSA). Useful for builder-time validation.

pub fn is_encryption(self) -> bool

Whether this algorithm can perform public-key encryption / key encapsulation. Maps to OpenPGP’s encryption-capable algorithms (RSA, ECDH, ElGamal, SM2).

Trait Implementations
