Class X509EncodedKeySpec

• java.lang.Object
• • java.security.spec.EncodedKeySpec
  • • java.security.spec.X509EncodedKeySpec

All Implemented Interfaces:

KeySpec

public class X509EncodedKeySpec
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

Constructors

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.

Methods

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".
