What is Base64 Encoding?

Base64 is an encoding scheme used to represent binary data in an ASCII string format. 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 ASCII. This is to ensure that the data remains intact without modification during transport (e.g. embedding image data in CSS or embedding tokens in HTTP Headers).
