Struct ring_compat::signature::ed25519::SigningKey

pub struct SigningKey { /* private fields */ }

Available on crate feature signature only.

Ed25519 signing key.

Implementations

impl SigningKey

pub const SIZE: usize = 32usize

Size of a raw SigningKey (a.k.a. seed) in bytes.

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

Available on crate feature rand_core only.

Generate a random Ed25519 key using the provided RNG.

pub fn from_bytes(seed: &[u8; 32]) -> Self

Create a new SigningKey from an unexpanded seed value (32-bytes).

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

Create a new SigningKey from a byte slice containing a seed value.

pub fn from_seed(seed: &[u8]) -> Result<Self>

👎Deprecated since 0.7.0: use from_slice instead

Alias for from_slice.

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

Serialize this SigningKey as a 32-byte “seed”.

pub fn verifying_key(&self) -> VerifyingKey

Get the VerifyingKey for this SigningKey.
