EcParameters

Enum EcParameters

pub enum EcParameters {
    NamedCurve(ObjectIdentifier),
}

Available on crate feature der only.

Expand description

Elliptic curve parameters as described in RFC5480 Section 2.1.1:

ECParameters ::= CHOICE {
  namedCurve         OBJECT IDENTIFIER
  -- implicitCurve   NULL
  -- specifiedCurve  SpecifiedECDomain
}
  -- implicitCurve and specifiedCurve MUST NOT be used in PKIX.
  -- Details for SpecifiedECDomain can be found in [X9.62].
  -- Any future additions to this CHOICE should be coordinated
  -- with ANSI X9.

Variants§

NamedCurve(ObjectIdentifier)

Elliptic curve named by a particular OID.

namedCurve identifies all the required values for a particular set of elliptic curve domain parameters to be represented by an object identifier.

Implementations§

impl EcParameters

pub fn named_curve(self) -> Option<ObjectIdentifier>
