What is Base64?
Base64 is an encoding scheme used to carry text and other data. It is used for simple obfuscation or to ensure data integrity in environments which only reliably support text content, such as websites and other software. The number 64 comes from the 64 ASCII characters which can be used in encoded Base64 data.
