```
void performOperation(TlsKeyOperation operation)
```
    Invoked each time a private key operation needs to be performed. You MUST call either operation.complete(output) or operation.completeExceptionally(exception) or the TLS connection will hang forever. You may complete the operation synchronously, or async. You may complete the operation on any thread. The function is always invoked from an IO event-loop thread. Therefore you MUST NOT perform an async call and wait for it in a blocking way from within this function. Such behavior is likely to deadlock your program. Additionally, this may be called from multiple times from multiple threads at once, so keep this in mind if using a private key operation that has to be single-threaded and synchronously called.
    
    Parameters:
    
    operation - The operation to be acted on
