Hi, Is there a way to convert a document contents to base64binary form usin

Hi,
Is there a way to convert a document contents to base64binary form using an expression function or an expression function plugin on a SAIL form? We are trying to integrate with DocuSign using SOAP API, and need a way to pass the document contents in base64binary form. Would appreciate your insight.
