What does base64 do in Linux?

Description. The base64 command encodes binary strings into text representations using the base64 encoding format.

What does XXD command do in Linux?

xxd creates a hex dump of a given file or standard input. It can also convert a hex dump back to its original binary form. Like uuencode(1) and uudecode(1) it allows the transmission of binary data in a ‘mail-safe’ ASCII representation, but has the advantage of decoding to standard output.

Can we decode Base64?

Base64 is an encoding, the strings you’ve posted are encoded. You can DECODE the base64 values into bytes (so just a sequence of bits). And from there, you need to know what these bytes represent and what original encoding they were represented in, if you wish to convert them again to a legible format.
