What exactly is Base64?

Base64 is a family of binary-to-text encoding techniques that convert binary data in an ASCII string format into a radix-64 representation.

Base64 is commonly used to encode binary data in email messages and web pages. It is also used to send binary files over channels that are not 8-bit clean or where byte order is not an issue.

Please see the Base64 Wikipedia page for further information.
