How does Base64 decode work?

Decoding base64
First, you remove any padding characters from the end of the encoded string. Then, you translate each base64 character back to their six-bit binary representation. Finally, you divide the bits into byte-sized (eight-bit) chunks and translate the data back to its original format.
