Enum cryptographic_message_syntax::SigningKey

pub enum SigningKey {
    Ecdsa(EcdsaKeyPair),
    Ed25519(Ed25519KeyPair),
    Rsa(RsaKeyPair),
}

Represents a key used for signing content.

This is a wrapper around ring’s key types supporting signing. We only care about the private key as this type should only be used for signing.

Variants

Ecdsa(EcdsaKeyPair)

ECDSA key pair.

Ed25519(Ed25519KeyPair)

ED25519 key pair.

Rsa(RsaKeyPair)

RSA key pair.

Implementations

impl SigningKey

pub fn from_pkcs8_der(
    data: &[u8],
    ecdsa_signing_algorithm: Option<&'static EcdsaSigningAlgorithm>
) -> Result<Self, CmsError>

Attempt to instantiate an instance from PKCS#8 DER data.

The document should be a OneAsymmetricKey data structure and should contain both the private and public key.

pub fn from_pkcs8_pem(
    data: &[u8],
    ecdsa_signing_algorithm: Option<&'static EcdsaSigningAlgorithm>
) -> Result<Self, CmsError>

Attempt to instantiate an instance from PEM encoded PKCS#8.

This is a convenience wrapper for PEM decoding and calling SigningKey::from_pkcs8_der.

pub fn sign(&self, message: &[u8]) -> Result<Vec<u8>, CmsError>

Sign a message using this signing key.

Returns the raw bytes constituting the signature.

pub fn public_key(&self) -> &[u8]

Obtain the raw bytes constituting the public key for this signing key.
