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 components_gf2m(
&self,
p: &mut BigNumRef,
a: &mut BigNumRef,
b: &mut BigNumRef,
ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
pub fn components_gf2m(
&self,
p: &mut BigNumRef,
a: &mut BigNumRef,
b: &mut BigNumRef,
ctx: &mut BigNumContextRef
) -> Result<(), ErrorStack>
Places the components of a curve over a binary field in the provided BigNum
s.
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 1
s or 5 1
s depending on
using a trinomial or pentanomial.

.
sourcepub fn degree(&self) -> u32
pub fn degree(&self) -> u32
Returns the degree of the curve.

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
.

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.
