UnknownKeyReceived Event

Signals that the server has introduced itself with an unknown key.

Syntax

typedef struct {
  String Algorithm;
  int Bits;
  String FingerprintSHA256;
  int Action;
} TsbxSFTPClientUnknownKeyReceivedEventParams;

typedef void __fastcall (__closure *TsbxSFTPClientUnknownKeyReceivedEvent)(System::TObject* Sender, TsbxSFTPClientUnknownKeyReceivedEventParams *e);

__property TsbxSFTPClientUnknownKeyReceivedEvent OnUnknownKeyReceived = { read=FOnUnknownKeyReceived, write=FOnUnknownKeyReceived };

Remarks

The component fires this event to tell the application that the server has introduced itself with a key not present in TrustedKeysFile. The details of the key are provided. In this event handler, you need to make a decision whether to proceed with the connection.

Use ServerKey to access more key details.

Use Action to tell the component what it should do with the key, supported values: catAcceptOnce = 1, catAcceptPermanently = 2, catReject = 3. Note that accepting an unknown and unchecked key may be risky.
