Base64 Encoding and Decoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. This means that any binary data, such as images, audio files, and executable programs, can be represented as a string of text characters. Base64 encoding is a way of representing binary data using a limited set of ASCII characters, making it easier to store, transmit, and share the data.

In computer science, encoding refers to the process of transforming data from one format to another to ensure that it can be properly interpreted by the intended recipient. Base64 encoding is often used for encoding binary data that needs to be transmitted over channels that are not 8-bit clean, such as email attachments or HTML files. In these cases, binary data is first encoded into base64 format before being transmitted. The recipient can then decode the base64 data back into its original binary format.

In addition to data transmission, base64 encoding is also used for data storage and encryption purposes. For example, web developers may use base64 encoding to store images and other multimedia files in web pages. Similarly, some encryption algorithms use base64 encoding to encode encrypted data in a format that can be transmitted over the internet.
