base64

Use

base64 -d encoded.txt

What It Does

base64 encodes or decodes base64 text.

Base64 turns arbitrary bytes into printable ASCII characters. It is useful for transport, not secrecy.

Practice

Use -d to decode when a puzzle gives base64-looking data.

Watch Out

Base64 is encoding, not encryption.

Docs Pointers

• Run man base64.
• Read file encoding.
