Struct libsecp256k1_core::curve::ECMultContext

pub struct ECMultContext { /* fields omitted */ }

Context for accelerating the computation of aP + bG.

Implementations

impl ECMultContext

pub fn ecdh_raw<D: Digest + Default>(
    &self,
    point: &Affine,
    scalar: &Scalar
) -> Option<GenericArray<u8, D::OutputSize>>

impl ECMultContext

pub fn verify_raw(
    &self,
    sigr: &Scalar,
    sigs: &Scalar,
    pubkey: &Affine,
    message: &Scalar
) -> bool

pub fn recover_raw(
    &self,
    sigr: &Scalar,
    sigs: &Scalar,
    rec_id: u8,
    message: &Scalar
) -> Result<Affine, Error>

impl ECMultContext

pub const unsafe fn new_from_raw(pre_g: [AffineStorage; 16384]) -> Self

Create a new ECMultContext from raw values.

Safety

The function is unsafe because incorrect value of pre_g can lead to crypto logic failure. You most likely do not want to use this function, but ECMultContext::new_boxed.

pub fn inspect_raw(&self) -> &[AffineStorage; 16384]

Inspect raw values of ECMultContext.

pub fn new_boxed() -> Box<Self>

Generate a new ECMultContext on the heap. Note that this function is expensive.

impl ECMultContext

pub fn ecmult(&self, r: &mut Jacobian, a: &Jacobian, na: &Scalar, ng: &Scalar)

pub fn ecmult_const(&self, r: &mut Jacobian, a: &Affine, scalar: &Scalar)
