Encode plain text to Base64 or decode a Base64 string back to plain text.
Mode
Base64 is a binary-to-text encoding scheme that converts binary data into a sequence of printable ASCII characters. It uses a set of 64 characters (A–Z, a–z, 0–9, +, /) to represent binary data, with "=" used for padding. Base64 is widely used to transmit binary data over text-based protocols such as email (MIME), embedding images in HTML/CSS, storing binary data in JSON, and in HTTP Basic Authentication headers.
