getP521 function
getP521 returns a EllipticCurve which implements NIST P-521 (FIPS 186-3, section D.2.5), also known as secp521r1. The CurveParams.Name of this Curve is "P-521".
Multiple invocations of this function will return the same value, so it can be used for equality checks and switch statements.
The cryptographic operations do not use constant-time algorithms.
Implementation
Curve getP521() {
return _p521;
}
