Class KeyRep
java.lang.Object
java.security.KeyRep
- All Implemented Interfaces:
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 Java Object Serialization Specification for more information.

KeyRep
Construct the alternate Key class.- Parameters:
type
- either one of Type.SECRET, Type.PUBLIC, or Type.PRIVATEalgorithm
- the algorithm returned fromKey.getAlgorithm()
format
- the encoding format returned fromKey.getFormat()
encoded
- the encoded bytes returned fromKey.getEncoded()
- Throws:
NullPointerException
- if type isnull
, if algorithm isnull
, if format isnull
, or if encoded isnull

Method Details
-
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:
- 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
