SilentisVox/Payload-Obfuscation — reverse-engineered prompt

Build me a small C learning project that demonstrates payload obfuscation in a safe way. I want it to take a byte array, hide it using two simple methods, then restore it back so I can see that the original data is unchanged.

The first method should be XOR encryption with a reusable key. The second should turn each byte into text that looks like normal letters, like the ALE idea in the README, then decode it back. Please make the code easy to read, with comments that explain what each step is doing, and include a simple example in main that prints the original bytes, the hidden version, and the decoded result.

Keep this educational only. Don’t add anything that injects code, runs shellcode, bypasses antivirus, or touches another machine. I just want a clean demo I can compile locally to understand how encoding and decoding byte data works.
