What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent 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 that are designed to deal with textual data, helping to ensure that the data remains intact without modification during transport.
