1. Introduction: Decoding the Hidden Messages You receive an email with an attachment. Your email client automatically converts it back from an encoded format into an image you can see. You visit a website and find an image embedded directly in the HTML code as a long string of garbled characters. You receive a message from an API containing data you cannot read because it is in encoded format. In all these cases, something has been Base64 encoded—translated from binary or text into a special format that is safe to transmit through systems that only understand text. But to actually use that data, you need to decode it. You need to reverse the translation and get the original information back. This is where the Base64 Decoder becomes essential. It is the inverse of the encoder. While an encoder takes readable data and scrambles it into a safe format, a decoder takes scrambled data and unscrambles it back into a readable form. In this guide, we will explore how decoding works, when you ...
