Base64url is a base64-based method to encode binary data as URL-encoded ASCII text so that the data can be transported in a URL.

It differs from base64 in that it forbids line separators and provides alternative character mappings for characters that have special meaning in URLs. For example, + in base64 becomes - in base64url and / in base64 becomes _ in base64url.
