Implementations

impl SigningKey

pub fn random(rng: &mut impl CryptoRngCore) -> Self

Generate a cryptographically random SigningKey.

pub fn from_bytes(bytes: &FieldBytes) -> Result<Self>

Initialize signing key from a raw scalar serialized as a byte array.

pub fn from_slice(bytes: &[u8]) -> Result<Self>

Initialize signing key from a raw scalar serialized as a byte slice.

pub fn to_bytes(&self) -> FieldBytes

Serialize this SigningKey as bytes

pub fn as_nonzero_scalar(&self) -> &NonZeroScalar

Borrow the secret NonZeroScalar value for this key.

⚠️ Warning

This value is key material.

Please treat it with the care it deserves!
