onUnknownKeyReceived (event)

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

Syntax

- (void)onUnknownKeyReceived:(NSString*)algorithm :(int)bits :(NSString*)fingerprintSHA256 :(int*)action;
func onUnknownKeyReceived(_ algorithm: String, _ bits: Int32, _ fingerprintSHA256: String, _ action: inout Int32)

Remarks

The class 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 class 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.
