(Go) RSA Encrypt with Modulus and Exponent

Demonstrates how to RSA encrypt with a given modulus and exponent.

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

    rsa := chilkat.NewRsa()

    // Assuming you already have a base64 modulus and exponent,
    // wrap it in XML like this:
    modulus := "qMBRpdYrAy5aMmo31NErUizh5sbweguSmh4wlK6uJEIDl+kwTlROnE34KOFExeTbJSX0WygPi+vWl0yNq7buIMUKpytossAAWut5khO3CQJxTk7G2gnEPNUUXHiExGgNrLzcSLv8YIlfVALhoRWyC67KOL+a+3taNq3h+BHeWhM="
    exponent := "AQAB"

    xml := chilkat.NewXml()
    xml.SetTag("RSAPublicKey")
    xml.NewChild2("Modulus",modulus)
    xml.NewChild2("Exponent",exponent)

    // Encrypt with the public key.
    publicKey := xml.GetXml()
    success := rsa.ImportPublicKey(*publicKey)

    usePrivateKey := false
    plainText := "message in a bottle"

    rsa.SetEncodingMode("base64")
