X509EncodedKeySpec (Java Platform SE 7 b138)

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

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.

    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".
