Decode hexadecimal XOR data

What it can do

• Parse hexadecimal bytes
• Apply a known byte key
• Recover readable output

How the recipe works

Demonstration

Sample input

7046514a424f4a59460347464e4c

Expected result

Serialize demo

When to use it

• Reverse-engineering classes
• CTF exercises
• Learning XOR's self-inverse property

Adapt it

Use XOR Brute Force only for intentionally weak one- or two-byte keys and verify candidates manually.

Source and verification

Adapted from UC Santa Cruz Slug Security: reverse-engineering walkthrough. The explanation and sample are written for Serialize, use synthetic or documentation-safe data, and are checked against the current operation catalogue. The workflow runs locally without an external API call.
