A little bit of Theory
Base64 is a binary-to-text encoding scheme. It can often be recognised by equal signs at the end of the data. However, this is not always the case. Linux has a command called
base64 that allows for encoding and decoding in Base64. For decoding, we need to use the flag
base64 command allows files as input, so we just need to use the command on the file.
