Struct Bls12381SecretKey 

pub struct Bls12381SecretKey { /* private fields */ }

Protected canonical nonzero BLS12-381 secret scalar.

This type deliberately implements neither Copy nor Clone and exposes no shared or mutable byte-slice trait. Use Self::to_bytes_zeroizing only when an explicit protected export is required.

Implementations

impl Bls12381SecretKey

pub fn from_bytes(bytes: &[u8]) -> ApiResult<Self>

Import a canonical 32-byte big-endian scalar in the range 1..r.

pub fn key_gen(ikm: &[u8], salt: &[u8]) -> ApiResult<Self>

Draft-07 KeyGen with the optional key_info value defaulting to empty.

ikm must contain at least 32 unpredictable bytes. Draft-07 requires callers to choose and supply salt; an empty salt is permitted by HKDF, but it is still an explicit caller choice.

pub fn key_gen_with_info( ikm: &[u8], salt: &[u8], key_info: &[u8], ) -> ApiResult<Self>

Draft-07 KeyGen with explicit caller-required salt and key_info.

pub fn generate<R: CryptoRng + RngCore>( rng: &mut R, salt: &[u8], ) -> ApiResult<Self>

Generate 32 bytes of IKM from a caller-supplied cryptographic RNG, then apply draft-07 KeyGen with an empty key_info value.

pub fn generate_with_info<R: CryptoRng + RngCore>( rng: &mut R, salt: &[u8], key_info: &[u8], ) -> ApiResult<Self>

Generate IKM from a caller-supplied RNG and apply draft-07 KeyGen.

pub fn public_key(&self) -> ApiResult<Bls12381PublicKey>

Derive the canonical minimum-size public key in G1.

pub fn to_bytes_zeroizing(&self) -> Zeroizing<[u8; 32]>

Export the canonical big-endian scalar in a clearing fixed-width owner.

Trait Implementations

impl Debug for Bls12381SecretKey

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Bls12381SecretKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
