sun.security.pkcs.PKCS8Key

org.openeuler.sun.security.ec.BGECPrivateKey

所有已实现的接口:

Serializable, ECKey, ECPrivateKey, Key, PrivateKey, Destroyable

public final class BGECPrivateKey
extends sun.security.pkcs.PKCS8Key
implements ECPrivateKey

Key implementation for SM2 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. This class is a modified version of the ECPrivateKeyImpl class in the Sun library, designed to adapt to the SM2 algorithm
