Base64url

Base64url is a method of encoding binary data into a text format that can be safely included in URLs or web communication. It converts data into a series of characters using a specific set of 64 symbols, similar to standard Base64, but replaces characters that can cause issues in URLs (like '+' and '/') with URL-safe characters ('-' and '_'). This encoding ensures data remains intact and easily transmitted over the web without confusion or errors caused by special characters, making it useful for secure data exchange, tokens, and web applications.
