Base64 Encoding Logic

$$\text{Base64}(x) = \text{encode}(\text{binary}(x)) \rightarrow \text{ASCII-safe string}$$

The input string is first converted into a byte sequence and then encoded using the Base64 algorithm.
Example:

• Hello world → SGVsbG8gd29ybGQ=

Base64 encoding is commonly used to transmit binary data (like images or files) over text-based protocols such as email, JSON, or HTML. This Base64 Encoder transforms plain text or binary input into a secure Base64 string, ensuring compatibility across systems. It’s especially useful for embedding data into scripts, APIs, or web applications.
