About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored or transferred over media designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport.
