What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /), with = used as padding. It's commonly used to embed binary data in text-based formats like HTML, CSS, JSON, and email (MIME).
Common use cases include Data URIs for embedding images, HTTP Basic Authentication headers, JWT token encoding, and transmitting binary data through text-only channels.
