How do I encode or decode Base64?

Encode or decode Base64

base64 ships with the system: pipe text or give a file to encode it, and add -D to decode.

How

Encode text:

printf "hello" | base64

Decode it back:

echo aGVsbG8= | base64 -D

Encode a whole file:

base64 -i logo.png -o logo.txt

Or just ask Titan

Decode this Base64 string and tell me what it says. Do it with Titan

Titan is an AI that lives on your computer: tell it what you need and it does it while you watch — you press Return, nothing runs by itself. What is Titan?

Titan isn’t on this computer yet. Get Titan, then press the button again — the task will be waiting, typed in.
