KeyRep
public class 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.

KeyRep
Added in API level 1
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
Added in API level 1
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 |
