Implementations
impl G1
[src]
pub fn binary_scalar_mul(
&self,
h: &Self,
a: &FieldElement,
b: &FieldElement
) -> Self
[src]
&self,
h: &Self,
a: &FieldElement,
b: &FieldElement
) -> Self
Computes sum of 2 scalar multiplications. Faster than doing the scalar multiplications individually and then adding them. Uses lookup table returns selfa + hb
pub fn hash_to_curve(domain_separation_tag: &[u8], msg: &[u8]) -> G1
[src]
Hashes a byte slice to a group element according to the hash to curve point IETF standard
https://datatracker.ietf.org/doc/draft-irtf-cfrg-hash-to-curve/?include_text=1
domain_separation_tag
should be unique between protocols as well as curves, eg. protocol A and
protocol B should use different domain_separation_tag
while hashing to the same curve and
protocol A should use different domain_separation_tag
while hashing to different curves.
Look at section 3.1 of the standard for more details
impl G1
[src]
pub fn to_ecp(&self) -> GroupG1
[src]
Return underlying elliptic curve point, ECP
pub fn scalar_mul_variable_time(&self, a: &FieldElement) -> Self
[src]
Multiply point on the curve (element of group G1) with a scalar. Variable time operation Uses wNAF.
pub fn get_multiples(&self, n: usize) -> Vec<G1>
[src]
Return multiples of itself. eg. Given n
=5, returns self, 2self, 3self, 4self, 5self
pub fn to_wnaf_lookup_table(&self, width: usize) -> G1LookupTable
[src]
pub fn wnaf_mul(table: &G1LookupTable, wnaf: &[i8]) -> Self
