Base64url
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.
