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

pub struct SecretKey(_);

A Secp256k1 secret key.

Implementations

impl SecretKey

pub fn generate() -> SecretKey

Generate a new random Secp256k1 secret key.

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

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.

Note that the expected binary format is the same as libsecp256k1’s.

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

Decode a DER-encoded Secp256k1 secret key in an ECPrivateKey structure as defined in RFC5915, zeroing the input slice on success.

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

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

Sign a raw message of length 256 bits with this secret key, produces a DER-encoded ECDSA signature.
