KeyRep
extends Object
implements
Serializable
java.lang.Object | |
↳ | java.security.KeyRep |
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.

Public constructors
KeyRep
public KeyRep (KeyRep.Type type, String algorithm, String format, byte[] encoded)
Construct the alternate Key class.
Parameters | |
---|---|
type |
KeyRep.Type : either one of Type.SECRET, Type.PUBLIC, or Type.PRIVATE |
algorithm |
String : the algorithm returned from
Key.getAlgorithm() |
format |
String : the encoding format returned from
Key.getFormat() |
encoded |
byte : 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
readResolve
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
Returns | |
---|---|
Object |
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 |
