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.

Method Summary

Constructor Details- 
KeyRepConstruct 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 Details- 
readResolveResolve 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
