(C# UWP/WinRT) IMAP Login SecureDemonstrates how to use the LoginSecure method introduced in Chilkat v9.5.0.71.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Imap imap = new Chilkat.Imap(); // Connect to an IMAP server.. imap.Ssl = true; imap.Port = 993; bool success = await imap.ConnectAsync("imap.mail.me.com"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Imagine we've previously saved our encrypted login and password within a JSON config file // that contains this: // { // "imap_login": "fLkxsfnVaIWLiL/R32jo6g==", // "imap_password": "/NbaFBoCftBLFf8WBU9Xtw==" // } Chilkat.JsonObject json = new Chilkat.JsonObject(); json.LoadFile("qa_data/passwords/imap.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("imap_login"),ssLogin); crypt.DecryptSecureENC(json.StringOf("imap_password"),ssPassword); // Pass the credentials to the LoginSecure method: success = await imap.LoginSecureAsync(ssLogin,ssPassword); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // ... await imap.DisconnectAsync(); |
