Methods

impl EcGroupRef

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 BigNums.

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 BigNums.

fn degree(&self) -> u32

Returns the degree of the curve.

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

Places the order of the curve in the provided BigNum.

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.

Trait Implementations

impl ForeignTypeRef for EcGroupRef

type CType = EC_GROUP

The raw C type.

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.
