Class PKCS8EncodedKeySpec

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

All Implemented Interfaces:

KeySpec

public class PKCS8EncodedKeySpec
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
 

Since:

1.2

Constructor Detail

PKCS8EncodedKeySpec

public PKCS8EncodedKeySpec(byte[] encodedKey)

Creates a new PKCS8EncodedKeySpec with the given encoded key.

Parameters:

encodedKey - the key, which is assumed to be encoded according to the PKCS #8 standard. The contents of the array are copied to protect against subsequent modification.

Throws:

NullPointerException - if encodedKey is null.
