What are cryptographic hashes?

  • 🔐 One-way function: Cannot be reversed to get original data
  • ✅ Verify integrity: Check if files haven't been modified
  • 🔑 Unique fingerprint: Each input produces a unique hash
  • 📊 SHA-256: Most commonly used for file verification
  • 🔒 SHA-512: More secure but longer hash

Did you know? SHA-256 is used to secure Bitcoin and other cryptocurrencies - every block in the blockchain contains a SHA-256 hash! Even changing a single character in the input completely changes the output hash (called the "avalanche effect"). Git uses SHA-1 hashes to track file changes. The SHA algorithms were designed by the NSA and published in 1993. It would take all the computers on Earth billions of years to crack a single SHA-256 hash!
