ExternalDecrypt Event

Handles remote or external decryption.

Syntax

class PGPReaderExternalDecryptEventParams {
public:
  const QString &OperationId();
  const QString &Algorithm();
  const QString &Pars();
  const QString &EncryptedData();
  const QString &Data();
  void SetData(const QString &qsData);
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ExternalDecrypt(PGPReaderExternalDecryptEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireExternalDecrypt(PGPReaderExternalDecryptEventParams *e) {...}

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives a encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contain algorithm-dependent parameters.

The component uses base16 (hex) encoding for EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

A sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16
