The Flaw Built Into Hashing: Pigeonhole Principle Explained

Описание: You blindly trust the company storing your password. But what actually happens to it?

Hashing.

🔑 Most systems hash it — turning your password into a fixed string of gibberish that can’t be reversed.
🔐 Some only encrypt it — scrambling it with a key, which can be unlocked.

But here’s the twist: thanks to the pigeonhole principle, every hash function has a flaw baked in.
Eventually, two different inputs will produce the same hash.

Most people don’t know this, but it’s one of the most fascinating truths in cybersecurity — and it reveals the limits of even our strongest protections.
