SFTP Authenticate Secure

Demonstrates how to do SFTP password authentication with secure strings.

This example requires Chilkat v9.5.0.71 or greater.

Go

    success := false

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

    // 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=="
    // }

    json := chilkat.NewJsonObject()
    json.LoadFile("qa_data/passwords/ssh.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("ssh_login"),ssLogin)
    crypt.DecryptSecureENC(*json.StringOf("ssh_password"),ssPassword)

    sftp := chilkat.NewSFtp()

    success = sftp.Connect("MY-SSH-SERVER-DOMAIN-OR-IP",22)
    if success != true {
        fmt.Println(sftp.LastErrorText())
        json.DisposeJsonObject()
        crypt.DisposeCrypt2()
        ssLogin.DisposeSecureString()
        ssPassword.DisposeSecureString()
        sftp.DisposeSFtp()
        return
    }

    // Authenticate using secure strings
    success = sftp.AuthenticateSecPw(ssLogin,ssPassword)
    if success != true {
        fmt.Println(sftp.LastErrorText())
        json.DisposeJsonObject()
        crypt.DisposeCrypt2()
        ssLogin.DisposeSecureString()
        ssPassword.DisposeSecureString()
        sftp.DisposeSFtp()
        return
    }

    fmt.Println("SFTP Authentication successful.")

    sftp.Disconnect()

    json.DisposeJsonObject()
    crypt.DisposeCrypt2()
    ssLogin.DisposeSecureString()
    ssPassword.DisposeSecureString()
    sftp.DisposeSFtp()
