But what does it actually do? And why would anyone need to “decrypt” a PNG — a format designed for lossless image compression, not encryption? if == " main ": xor_decrypt("encrypted

Real‑world PNG encryption often involves AES, custom chunk ordering, or LSB steganography — requiring far more complex logic. The Ethics of PNG Decryption Decrypting a PNG you own or have explicit permission to analyze is fine. Decrypting a PNG to bypass access controls or steal data is not .

Whether you’re a forensic analyst, a hacker, or a curious developer — understanding PNG decryption teaches you more about how image formats actually work. But like any powerful tool, it demands responsibility.
