// See Global Unlock Sample for sample code.

ssh := TChilkatSsh.Create(Self);

// To get the authentication methods offered by an SSH server, we first connect.
success := ssh.Connect('example.com',22);
if (success <> 1) then
  begin
    Memo1.Lines.Add(ssh.LastErrorText);
    Exit;
  end;

// Next, we call GetAuthMethods to receive a comma separated list of authentication methods
authMethods := ssh.GetAuthMethods();
if (ssh.LastMethodSuccess <> 1) then
  begin
    Memo1.Lines.Add(ssh.LastErrorText);
    Exit;
  end;

// For example: publickey,password,keyboard-interactive
Memo1.Lines.Add('Authentication methods suported by this serve: ' + authMethods);

// IMPORTANT:
// Getting the authentication methods will intentionally disconnect from the server.
// We'll need to re-connect, etc. to continue..

// For example..
success := ssh.Connect('example.com',22);
if (success <> 1) then
  begin
    Memo1.Lines.Add(ssh.LastErrorText);
    Exit;
  end;
success := ssh.AuthenticatePw('myLogin','myPassword');
if (success <> 1) then
  begin
    Memo1.Lines.Add(ssh.LastErrorText);
    Exit;
  end;

Memo1.Lines.Add('SSH Authentication successful.');
