Base64 Encoding Principles
Base64 encodes 8-bit binary streams into 6-bit chunks mapped to 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). It is widely used in MIME email attachments, JSON payloads, and JWT tokens.
URL-Safe Base64 (RFC 4648) replaces + with - and / with _, removing trailing = padding for URL and filename compatibility.
