Conversion from Base64 to Base64url
When working with data encoding, you may encounter the need to convert between different formats like Base64 and Base64url. Base64 is a encoding scheme that represents binary data in an ASCII string format using a set of 64 different characters. Base64 is known for its use in encoding data for purposes such as data transmission over the internet or storing binary data in a text-based format.
Base64url is a variant of Base64 that is URL-safe and does not use characters like '+' or '/' which have special meanings in URLs. To convert data encoded in Base64 to Base64url, the '+' and '/' characters are replaced by '-' and '_', respectively. This conversion factor ensures that the resulting Base64url encoded data can be safely used within URLs without the need for encoding or escaping special characters, making it more suitable for web applications and APIs. Other common usecases for converting Base64 to Base64url include working with JWT tokens, encoding data for transmission in URLs within applications, and ensuring compatibility with systems or libraries that expect data in the Base64url format.
