    About Cryptographic Hashing

    A cryptographic hash function converts any input into a fixed-size string of characters. The same input always produces the same hash, but even a tiny change creates a completely different output (the "avalanche effect").

    Common Uses

    • Verifying file downloads haven't been tampered with
    • Storing passwords securely (with salting)
    • Digital signatures and certificates
    • Data integrity in version control (Git uses SHA-1)
    • Blockchain and cryptocurrency

    Security Notes

    • MD5 and SHA-1 are broken for security use
    • Use SHA-256 or higher for cryptographic purposes
    • For passwords, use bcrypt/scrypt/Argon2 instead of raw hashes
    • Always verify downloads using hashes from a trusted source
