🔐 File Hash Calculator

Calculate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for file integrity verification and security.

What are file hashes?

A hash is a unique fingerprint of a file. Even the smallest change to a file will result in a completely different hash.

Use Cases:

Verify file integrity: Compare the hash with the official hash to ensure the file wasn't corrupted or tampered with
Detect duplicates: Files with identical hashes are exact duplicates
Security verification: Verify downloaded software hasn't been modified by malicious actors

Hash Algorithms:

MD5: Fast but cryptographically broken. Good for quick file checks but not for security.
SHA-1: Deprecated for security use but still common for git commits and older systems.
SHA-256: Current industry standard for cryptographic security.
SHA-512: More secure variant of SHA-256 with longer hash output.
