Class ECPrivateKeyImpl

java.lang.Object

com.tencent.kona.sun.security.pkcs.PKCS8Key

com.tencent.kona.sun.security.ec.ECPrivateKeyImpl

All Implemented Interfaces:

java.io.Serializable, java.security.interfaces.ECKey, java.security.interfaces.ECPrivateKey, java.security.Key, java.security.PrivateKey, javax.security.auth.Destroyable

public final class ECPrivateKeyImpl
extends PKCS8Key
implements java.security.interfaces.ECPrivateKey

Key implementation for EC private keys. ASN.1 syntax for EC private keys from SEC 1 v1.5 (draft):

 EXPLICIT TAGS

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

We currently ignore the optional parameters and publicKey fields. We require that the parameters are encoded as part of the AlgorithmIdentifier, not in the private key structure.

Since:

1.6
