What is Base64?

Base64 represents binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remain intact without modification during transport.
