Struct ring::signature::EcdsaKeyPair

pub struct EcdsaKeyPair { /* fields omitted */ }

An ECDSA key pair, used for signing.

Implementations

impl EcdsaKeyPair

pub fn generate_pkcs8(
    alg: &'static EcdsaSigningAlgorithm,
    rng: &dyn SecureRandom
) -> Result<Document, Unspecified>

Generates a new key pair and returns the key pair serialized as a PKCS#8 document.

The PKCS#8 document will be a v1 OneAsymmetricKey with the public key included in the ECPrivateKey structure, as described in RFC 5958 Section 2 and RFC 5915. The ECPrivateKey structure will not have a parameters field so the generated key is compatible with PKCS#11.

pub fn from_pkcs8(
    alg: &'static EcdsaSigningAlgorithm,
    pkcs8: &[u8]
) -> Result<Self, KeyRejected>

Constructs an ECDSA key pair by parsing an unencrypted PKCS#8 v1 id-ecPublicKey ECPrivateKey key.

The input must be in PKCS#8 v1 format. It must contain the public key in the ECPrivateKey structure; from_pkcs8() will verify that the public key and the private key are consistent with each other. The algorithm identifier must identify the curve by name; it must not use an “explicit” encoding of the curve. The parameters field of the ECPrivateKey, if present, must be the same named curve that is in the algorithm identifier in the PKCS#8 header.

pub fn from_private_key_and_public_key(
    alg: &'static EcdsaSigningAlgorithm,
    private_key: &[u8],
    public_key: &[u8]
) -> Result<Self, KeyRejected>

Constructs an ECDSA key pair directly from the big-endian-encoded private key and public key bytes.

This is intended for use by code that deserializes key pairs. It is recommended to use RsaPubeyPair::from_pkcs8() (with a PKCS#8-encoded key) instead.

pub fn sign(
    &self,
    rng: &dyn SecureRandom,
    message: &[u8]
) -> Result<Signature, Unspecified>

Returns the signature of the message using a random nonce generated by rng.
