What is Base64 Encoding and why is it used?

Base64 encoding is a way to convert any binary or text data into a printable ASCII string format.

It is needed to safely transmit binary data over a transmission protocol/medium that does not support/handle binary data correctly.

Note that, Base64 is not an encryption or compression scheme. It is an encoding scheme that converts binary data like an image or file to the ASCII character set.

It is called Base64 because it works with a subset of 64 characters from the ASCII character set. These characters include upper and lowercase alphabets (A-Za-z), digits (0-9), +, and /.

These 64 characters form the Base64 alphabet. Note that, the Base64 encoding scheme also uses an extra 65th character = as a pad character.
