Class PKCS8EncodedKeySpec

java.lang.Object
 extended by java.security.spec.EncodedKeySpec
 extended by 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

Since:: 1.2

`PKCS8EncodedKeySpec(byte[] encodedKey)` Creates a new PKCS8EncodedKeySpec with the given encoded key.

Method Summary
`byte[]`	`getEncoded()` Returns the key bytes, encoded according to the PKCS #8 standard.
`String`	`getFormat()` Returns the name of the encoding format associated with this key specification.

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.

Method Detail

getEncoded

public byte[] getEncoded()

Returns the key bytes, encoded according to the PKCS #8 standard.

Overrides:: getEncoded in class EncodedKeySpec

Returns:: the PKCS #8 encoding of the key. Returns a new array each time this method is called.

getFormat

public final String getFormat()

Returns the name of the encoding format associated with this key specification.

Specified by:: getFormat in class EncodedKeySpec

Returns:: the string "PKCS#8".
