Class RFC5915ECPrivateKeyEncodedKeySpec

java.lang.Object

java.security.spec.EncodedKeySpec

ibm.security.internal.spec.RFC5915ECPrivateKeyEncodedKeySpec

All Implemented Interfaces:

java.security.spec.KeySpec

public class RFC5915ECPrivateKeyEncodedKeySpec
extends java.security.spec.EncodedKeySpec

This class represents the ASN.1 encoding of an EC private key, encoded according to the ASN.1 type ECPrivateKey. The ECPrivateKey syntax is defined in RFC5915 standard as follows:

 ECPrivateKey ::= SEQUENCE {
   version        INTEGER { ecPrivkeyVer1(1) } (ecPrivkeyVer1),
   privateKey     OCTET STRING,
   parameters [0] ECParameters {{ NamedCurve }} OPTIONAL,
   publicKey  [1] BIT STRING OPTIONAL
 }
