Package Summary Overview Summary

class:KeyRep [NONE]

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

constructor:<init>(java.security.KeyRep.Type,java.lang.String,java.lang.String,byte[]) [NONE]

KeyRep
```
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

method:readResolve() [NONE]

readResolve
```
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
