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.

Returns an integer hash code for this object.
|
|
final
void
|
notify()
Causes a thread which is waiting on this object's monitor (by means of
calling one of the wait() methods) to be woken up.
|
|
final
void
|
notifyAll()
Causes all threads which are waiting on this object's monitor (by means
of calling one of the wait() methods) to be woken up.
|
|
String
|
toString()
Returns a string containing a concise, human-readable description of this
object.
|
|
final
void
|
wait(long timeout, int nanos)
Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the
specified timeout expires.
|
|
final
void
|
wait(long timeout)
Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the
specified timeout expires.
|
|
final
void
|
wait()
Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors
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 Methods
protected
Object
readResolve
()
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
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
