Concept

Handling encoded data (Base64).

Key Commands

base64 -d

Walkthrough

The password is stored in data.txt as a Base64 encoded string. To retrieve the clear-text password, we use the base64 utility with the -d (decode) flag.

base64 -d data.txt

Key Takeaways

• Encoding vs. Encryption: Base64 is NOT encryption; it is an encoding scheme used to represent binary data in an ASCII string format.
• Flags matter: Running base64 without flags will encode the input instead of decoding it.
