Struct libp2p::core::identity::secp256k1::SecretKey

pub struct SecretKey(_);

A Secp256k1 secret key.

Methods

impl SecretKey

pub fn generate() -> SecretKey

Generate a new Secp256k1 secret key.

pub fn from_bytes<impl AsMut<[u8]>>(
    sk: impl AsMut<[u8]>
) -> Result<SecretKey, DecodingError> where
    impl AsMut<[u8]>: AsMut<[u8]>, 

Create a secret key from a byte slice, zeroing the slice on success. If the bytes do not constitute a valid Secp256k1 secret key, an error is returned.

pub fn from_der<impl AsMut<[u8]>>(
    der: impl AsMut<[u8]>
) -> Result<SecretKey, DecodingError> where
    impl AsMut<[u8]>: AsMut<[u8]>, 

Decode a DER-encoded Secp256k1 secret key in an ECPrivateKey structure as defined in RFC5915.

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

Sign a message with this secret key, producing a DER-encoded ECDSA signature, as defined in RFC3278.

pub fn to_bytes(&self) -> [u8; 32]

Returns the raw bytes of the secret key.
