Methods

impl EcGroupRef[src]

pub fn components_gfp(
    &self,
    p: &mut BigNumRef,
    a: &mut BigNumRef,
    b: &mut BigNumRef,
    ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
[src]

Places the components of a curve over a prime field in the provided BigNums. The components make up the formula y^2 mod p = x^3 + ax + b mod p.

OpenSSL documentation available at EC_GROUP_get_curve_GFp

pub fn components_gf2m(
    &self,
    p: &mut BigNumRef,
    a: &mut BigNumRef,
    b: &mut BigNumRef,
    ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
[src]

Places the components of a curve over a binary field in the provided BigNums. The components make up the formula y^2 + xy = x^3 + ax^2 + b.

In this form p relates to the irreducible polynomial. Each bit represents a term in the polynomial. It will be set to 3 1s or 5 1s depending on using a trinomial or pentanomial.

pub fn cofactor(
    &self,
    cofactor: &mut BigNumRef,
    ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
[src]

Places the cofactor of the group in the provided BigNum.

OpenSSL documentation at EC_GROUP_get_cofactor

pub fn degree(&self) -> u32[src]

Returns the degree of the curve.

OpenSSL documentation at EC_GROUP_get_degree

pub fn order_bits(&self) -> u32[src]

Returns the number of bits in the group order.

OpenSSL documentation at EC_GROUP_order_bits

pub fn generator(&self) -> &EcPointRef[src]

Returns the generator for the given curve as a EcPoint.

OpenSSL documentation at EC_GROUP_get0_generator

pub fn order(
    &self,
    order: &mut BigNumRef,
    ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
[src]

Places the order of the curve in the provided BigNum.

OpenSSL documentation at EC_GROUP_get_order

pub fn set_asn1_flag(&mut self, flag: Asn1Flag)[src]

Sets the flag determining if the group corresponds to a named curve or must be explicitly parameterized.

This defaults to EXPLICIT_CURVE in OpenSSL 1.0.1 and 1.0.2, but NAMED_CURVE in OpenSSL 1.1.0.

pub fn curve_name(&self) -> Option<Nid>[src]

Returns the name of the curve, if a name is associated.
