UnknownKeyReceived Event
Signals that the server has introduced itself with an unknown key.
Syntax
public class DefaultSftpclientEventListener implements SftpclientEventListener { ... public void unknownKeyReceived(SftpclientUnknownKeyReceivedEvent e) {} ... } public class SftpclientUnknownKeyReceivedEvent { public String algorithm; public int bits; public String fingerprintSHA256; public int action; }
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.
