IMAP Login Secure

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

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    imap := chilkat.NewImap()

    // Connect to an IMAP server..
    imap.SetSsl(true)
    imap.SetPort(993)
    success = imap.Connect("imap.mail.me.com")
    if success != true {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        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=="
    // }

    json := chilkat.NewJsonObject()
    json.LoadFile("qa_data/passwords/imap.json")

    crypt := chilkat.NewCrypt2()

    // These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
    crypt.SetCryptAlgorithm("aes")
    crypt.SetCipherMode("cbc")
    crypt.SetKeyLength(128)
    crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
    crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
    crypt.SetEncodingMode("base64")

    ssLogin := chilkat.NewSecureString()
    ssPassword := chilkat.NewSecureString()

    // 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 {
        fmt.Println(imap.LastErrorText())
        imap.DisposeImap()
        json.DisposeJsonObject()
        crypt.DisposeCrypt2()
        ssLogin.DisposeSecureString()
        ssPassword.DisposeSecureString()
        return
    }

    // ...

    imap.Disconnect()

    imap.DisposeImap()
    json.DisposeJsonObject()
    crypt.DisposeCrypt2()
    ssLogin.DisposeSecureString()
    ssPassword.DisposeSecureString()
