What is Base64 Encoding / 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. It is commonly used to encode data that needs to be stored and transferred over media designed to deal with textual data. Base64 decoding is the reverse process, converting the encoded ASCII string back to its original binary form.
