    • setMustProduceEncodableUnwrappedKey

      public JceAsymmetricKeyUnwrapper setMustProduceEncodableUnwrappedKey(boolean unwrappedKeyMustBeEncodable)
      Flag that unwrapping must produce a key that will return a meaningful value from a call to Key.getEncoded(). This is important if you are using a HSM for unwrapping and using a software based provider for with the unwrapped key. Default value: false.
      Parameters:
      unwrappedKeyMustBeEncodable - true if getEncoded() should return key bytes, false if not necessary.
      Returns:
      this recipient.

    • setAlgorithmMapping

      public JceAsymmetricKeyUnwrapper setAlgorithmMapping(org.bouncycastle.asn1.ASN1ObjectIdentifier algorithm, String algorithmName)
      Internally algorithm ids are converted into cipher names using a lookup table. For some providers the standard lookup table won't work. Use this method to establish a specific mapping from an algorithm identifier to a specific algorithm.

      For example: 

           unwrapper.setAlgorithmMapping(PKCSObjectIdentifiers.rsaEncryption, "RSA");
      Parameters:
      algorithm - OID of algorithm in recipient.
      algorithmName - JCE algorithm name to use.
      Returns:
      the current Unwrapper.
