Enum x509_certificate::algorithm::SignatureAlgorithm [−][src]
pub enum SignatureAlgorithm { RsaSha1, RsaSha256, RsaSha384, RsaSha512, 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.
Variants
SHA-1 with RSA encryption.
Corresponds to OID 1.2.840.113549.1.1.5.
SHA-256 with RSA encryption.
Corresponds to OID 1.2.840.113549.1.1.11.
SHA-384 with RSA encryption.
Corresponds to OID 1.2.840.113549.1.1.12.
SHA-512 with RSA encryption.
Corresponds to OID 1.2.840.113549.1.1.13.
ECDSA with SHA-256.
Corresponds to OID 1.2.840.10045.4.3.2.
ECDSA with SHA-384.
Corresponds to OID 1.2.840.10045.4.3.3.
ED25519
Corresponds to OID 1.3.101.112.
Implementations
impl SignatureAlgorithm
[src]
impl SignatureAlgorithm
[src]pub fn from_oid_and_digest_algorithm(
oid: &Oid,
digest_algorithm: DigestAlgorithm
) -> Result<Self, Error>
[src]
pub fn from_oid_and_digest_algorithm(
oid: &Oid,
digest_algorithm: DigestAlgorithm
) -> Result<Self, Error>
[src]Attempt to resolve an instance from an OID, known KeyAlgorithm, and optional DigestAlgorithm.
Signature algorithm OIDs in the wild are typically either:
a) an OID that denotes the key algorithm and corresponding digest format (what this enumeration represents) b) an OID that denotes just the key algorithm.
What this function does is attempt to construct an instance from any OID. If the OID defines a key + digest algorithm, we get a SignatureAlgorithm from that. If we get a key algorithm we combine with the provided DigestAlgorithm to resolve an appropriate SignatureAlgorithm.
pub fn resolve_verification_algorithm(
&self,
key_algorithm: KeyAlgorithm
) -> Result<&'static dyn VerificationAlgorithm, Error>
[src]
pub fn resolve_verification_algorithm(
&self,
key_algorithm: KeyAlgorithm
) -> Result<&'static dyn VerificationAlgorithm, Error>
[src]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.
