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 KeyRep
(Type type, String algorithm, String format, byte[] encoded)
Construct the alternate Key class.
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
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
