Class PKCS8EncodedKeySpec

java.lang.Object
  java.security.spec.EncodedKeySpec
      java.security.spec.PKCS8EncodedKeySpec

All Implemented Interfaces:: KeySpec

public class PKCS8EncodedKeySpec
extends EncodedKeySpec
extends EncodedKeySpec

This class represents the ASN.1 encoding of a private key, encoded according to the ASN.1 type PrivateKeyInfo. The PrivateKeyInfo syntax is defined in the PKCS#8 standard as follows:

 PrivateKeyInfo ::= SEQUENCE {
   version Version,
   privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
   privateKey PrivateKey,
   attributes [0] IMPLICIT Attributes OPTIONAL }

 Version ::= INTEGER

 PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier

 PrivateKey ::= OCTET STRING

 Attributes ::= SET OF Attribute
