Handles remote or external decryption.
func onExternalDecrypt(operationId: String, algorithm: String, pars: String, encryptedData: String, data: inout String)
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.
