Class KeyRep

java.lang.Object
java.security.KeyRep
All Implemented Interfaces:
Serializable
public class KeyRep extends Object implements 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.

  • Constructor Details

    • KeyRep

      public KeyRep(KeyRep.Type type, String algorithm, String format, byte[] encoded)
      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

  • Method Details

    • readResolve

      protected Object readResolve() throws ObjectStreamException
      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
