IMAP Login Secure

Demonstrates how to use the LoginSecure method introduced in Chilkat v9.5.0.71. C#

bool success = false;

// 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;
success = imap.Connect("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 = imap.LoginSecure(ssLogin,ssPassword);
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// ...

imap.Disconnect();
