Example 26 with ECGenParameterSpec

use of java.security.spec.ECGenParameterSpec in project jdk8u_jdk by JetBrains.

the class SupportedEllipticCurvesExtension method isAvailableCurve.

// check whether the curve is supported by the underlying providers
private static boolean isAvailableCurve(int curveId) {
    String oid = idToOidMap.get(curveId);
    if (oid != null) {
        AlgorithmParameters params = null;
        try {
            params = JsseJce.getAlgorithmParameters("EC");
            params.init(new ECGenParameterSpec(oid));
        } catch (Exception e) {
            return false;
        }
        // cache the parameters
        idToParams.put(curveId, params);
