Base64

Base64 is a method of encoding data which is widely used in the context of Geometry Dash.

GD uses a variant of Base64 called url safe Base64 which replaces characters that may unintentionally break requests sent to the servers

Table of characters

This table covers the characters url safe base64 use

Padding

The padding character is = however, it is optional as the Geometry Dash servers will automatically correct strings that do not have any padding
