impl EcGroupRef
sourcepub fn components_gfp(
&self,
p: &mut BigNumRef,
a: &mut BigNumRef,
b: &mut BigNumRef,
ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
pub fn components_gfp( &self, p: &mut BigNumRef, a: &mut BigNumRef, b: &mut BigNumRef, ctx: &mut BigNumContextRef ) -> Result<(), ErrorStack>
Places the components of a curve over a prime field in the provided BigNum
s.
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
sourcepub fn cofactor(
&self,
cofactor: &mut BigNumRef,
ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
pub fn cofactor( &self, cofactor: &mut BigNumRef, ctx: &mut BigNumContextRef ) -> Result<(), ErrorStack>
Places the cofactor of the group in the provided BigNum
.

sourcepub fn degree(&self) -> u32
pub fn degree(&self) -> u32
Returns the degree of the curve.
OpenSSL documentation at EC_GROUP_get_degree
sourcepub fn order_bits(&self) -> u32
pub fn order_bits(&self) -> u32
Returns the number of bits in the group order.
OpenSSL documentation at EC_GROUP_order_bits
sourcepub fn generator(&self) -> &EcPointRef
pub fn generator(&self) -> &EcPointRef
Returns the generator for the given curve as a EcPoint
.
OpenSSL documentation at EC_GROUP_get0_generator
sourcepub fn order(
&self,
order: &mut BigNumRef,
ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
pub fn order( &self, order: &mut BigNumRef, ctx: &mut BigNumContextRef ) -> Result<(), ErrorStack>
Places the order of the curve in the provided BigNum
.
OpenSSL documentation at EC_GROUP_get_order
sourcepub fn set_asn1_flag(&mut self, flag: Asn1Flag)
pub fn set_asn1_flag(&mut self, flag: Asn1Flag)
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.
sourcepub fn curve_name(&self) -> Option<Nid>
pub fn curve_name(&self) -> Option<Nid>
Returns the name of the curve, if a name is associated.
