All Implemented Interfaces:

Serializable
```
public class KeyRep
extends Object
implements Serializable
```
Standardized representation for serialized Key objects.
Note that a serialized Key may contain sensitive information which should not be exposed in untrusted environments. See the Security Appendix of the Serialization Specification for more information.

Since:

1.5

```
public KeyRep(KeyRep.Type type,
      String algorithm,
      String format,
      byte[] encoded)
```
    Construct the alternate Key class.
    
    Parameters:
    type - either one of Type.SECRET, Type.PUBLIC, or Type.PRIVATE
    algorithm - the algorithm returned from Key.getAlgorithm()
    format - the encoding format returned from Key.getFormat()
    encoded - the encoded bytes returned from Key.getEncoded()
    
    Throws:
    
    NullPointerException - if type is null, if algorithm is null, if format is null, or if encoded is null

```
protected Object readResolve()
                      throws ObjectStreamException
```
    Resolve the Key object.
    This method supports three Type/format combinations:
    - Type.SECRET/"RAW" - returns a SecretKeySpec object constructed using encoded key bytes and algorithm
    - Type.PUBLIC/"X.509" - gets a KeyFactory instance for the key algorithm, constructs an X509EncodedKeySpec with the encoded key bytes, and generates a public key from the spec
    - Type.PRIVATE/"PKCS#8" - gets a KeyFactory instance for the key algorithm, constructs a PKCS8EncodedKeySpec with the encoded key bytes, and generates a private key from the spec
    Returns:
    the resolved Key object
    
    Throws:
    
    ObjectStreamException - if the Type/format combination is unrecognized, if the algorithm, key format, or encoded key bytes are unrecognized/invalid, of if the resolution of the key fails for any reason
