What is Base64 Encoding?
Base64 is an encoding scheme that translates binary data into a text string format using exactly 64 ASCII characters. It is commonly used in programmatic environments where you need to transmit binary data over media that are designed to deal with textual data (like JSON, XML, or HTML).
