(Mono C#) SSH Authenticate SecureDemonstrates how to do SSH password authentication with secure strings. This example requires Chilkat v9.5.0.71 or greater.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. bool success; // Imagine we've previously saved our encrypted login and password within a JSON config file // that contains this: // { // "ssh_login": "2+qylFfC56Ck7OQQt/U2/w==", // "ssh_password": "5neIq9Jmn0E3p71N6Yc8TA==" // } Chilkat.JsonObject json = new Chilkat.JsonObject(); json.LoadFile("qa_data/passwords/ssh.json"); Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); // These are the encryption settings we previously used to encrypt the credentials within the JSON config file. crypt.CryptAlgorithm = "aes"; crypt.CipherMode = "cbc"; crypt.KeyLength = 128; crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex"); crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex"); crypt.EncodingMode = "base64"; Chilkat.SecureString ssLogin = new Chilkat.SecureString(); Chilkat.SecureString ssPassword = new Chilkat.SecureString(); // Decrypt to the secure string. (the strings will still held in memory encrypted, but are now encrypted using // a randomly generated session key.) crypt.DecryptSecureENC(json.StringOf("ssh_login"),ssLogin); crypt.DecryptSecureENC(json.StringOf("ssh_password"),ssPassword); Chilkat.Ssh ssh = new Chilkat.Ssh(); success = ssh.Connect("MY-SSH-SERVER-DOMAIN-OR-IP",22); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } // Authenticate using secure strings success = ssh.AuthenticateSecPw(ssLogin,ssPassword); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } Debug.WriteLine("SSH Authentication successful."); ssh.Disconnect(); |
