Struct SecretKey

pub struct SecretKey(/* private fields */);

Available on crate feature secp256k1 only.

A Secp256k1 secret key.

Implementations

impl SecretKey

pub fn generate() -> SecretKey

Available on crate feature rand only.

Generate a new random Secp256k1 secret key.

pub fn try_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]) -> Vec<u8>

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.
