Base64url Encoding

See more Encryption Examples

Base64url encoding is identical to base64 encoding except it uses non-reserved URL characters (e.g. '–' is used instead of '+', and '_' is used instead of '/') and it omits the padding characters. PHP Extension

<?php

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