All Implemented Interfaces:: KeySpec

public class X509EncodedKeySpec
extends EncodedKeySpec
extends EncodedKeySpec

This class represents the ASN.1 encoding of a public key, encoded according to the ASN.1 type SubjectPublicKeyInfo. The SubjectPublicKeyInfo syntax is defined in the X.509 standard as follows:

 SubjectPublicKeyInfo ::= SEQUENCE {
 algorithm AlgorithmIdentifier,
 subjectPublicKey BIT STRING }

Since:: 1.2

Constructor Detail

X509EncodedKeySpec

public X509EncodedKeySpec(byte[] encodedKey)

Creates a new X509EncodedKeySpec with the given encoded key.

Parameters:: encodedKey - the key, which is assumed to be encoded according to the X.509 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 X.509 standard.

Overrides:: getEncoded in class EncodedKeySpec

Returns:: the X.509 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 "X.509".
