Enum x509_certificate::algorithm::SignatureAlgorithm

pub enum SignatureAlgorithm {
    Sha1Rsa,
    Sha256Rsa,
    Sha512Rsa,
    RsaesPkcsV15,
    EcdsaSha256,
    EcdsaSha384,
    Ed25519,
}

An algorithm used to digitally sign content.

Instances can be converted to/from Oid via From/Into.

Similarly, instances can be converted to/from an ASN.1 AlgorithmIdentifier.

It is also possible to obtain a signature::VerificationAlgorithm from an instance. This type can perform actual cryptographic verification that was signed with this algorithm.

Implementations

impl SignatureAlgorithm

pub fn resolve_verification_algorithm(
    &self,
    key_algorithm: KeyAlgorithm
) -> Result<&'static dyn VerificationAlgorithm, Error>

Attempt to resolve the verification algorithm using info about the signing key algorithm.

Only specific combinations of methods are supported. e.g. you can only use RSA verification with RSA signing keys. Same for ECDSA and ED25519.
