UnknownKeyReceived Event
Signals that the server has introduced itself with an unknown key.
Syntax
typedef struct { String Algorithm; int Bits; String FingerprintSHA256; int Action; } TsbiSFTPClientUnknownKeyReceivedEventParams; typedef void __fastcall (__closure *TsbiSFTPClientUnknownKeyReceivedEvent)(System::TObject* Sender, TsbiSFTPClientUnknownKeyReceivedEventParams *e); __property TsbiSFTPClientUnknownKeyReceivedEvent 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.
