UnknownKeyReceived Event

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

Syntax

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.
