Fun Fact About Base64

Base64 encoding does not actually encrypt data. It only converts binary information into a text format using 64 characters so it can be safely transmitted through systems that only support plain text. Anyone can decode Base64 without a password.

Historical Context of Base64 Encoding

Base64 was originally developed as part of the MIME standard in the early days of the internet. Email systems were designed to handle only simple text characters, which made it difficult to send binary files such as images and documents.

To solve this limitation, Base64 encoding was introduced as a method to represent binary data using only standard ASCII characters. Over time, it became a universal way to embed images in HTML, transmit tokens in APIs, and store structured data in text-based formats.

Even today, Base64 remains one of the most widely used encoding techniques in web technologies, programming, and digital communication.
