Introduction to Base64 Decoding
Base64 encoding is a method used to convert binary data into a text format, making it easier to store and transfer through systems that handle text-based data, such as emails, URLs, and APIs.
However, to restore the original data, Base64 decoding is required.
Unlike encryption, Base64 encoding does not provide security—it simply converts data into a readable format that can be reversed with decoding.
Common applications include decoding email attachments, restoring encoded text, and handling embedded images in web pages.
