Continue SSH Keyboard-Interactive Authentication
See more SSH Examples
Demonstrates the Chilkat Ssh.ContinueKeyboardAuth method, which submits a response to a keyboard-interactive prompt. The only argument is the response text; for a request containing multiple prompts, an XML response is supplied instead. It returns XML indicating the next prompt or the final result.
Background: This is the second half of the keyboard-interactive exchange started by
StartKeyboardAuth. A server may issue several rounds of prompts, so a robust client loops: submit answers, read the returned XML, and continue until authentication succeeds or fails. Prompt responses are typically secrets, so obtain them from interactive input rather than embedding them in code.Chilkat PowerBuilder Downloads
