Hash Generator

What this does

A cryptographic hash converts any input into a fixed-length fingerprint. Same input → same hash, every time. Useful for verifying file integrity, generating cache keys, deduplicating data, or comparing two strings without exposing them. We compute all four common algorithms simultaneously so you can pick whichever your tool expects.

Security notes

• MD5 and SHA-1 are cryptographically broken — fine for non-security uses (cache keys, ETags) but never use them for password storage or signatures.
• SHA-256 and SHA-512 are still secure. Use them for integrity checks and as building blocks for HMAC / signatures.
• For password storage specifically, use a slow KDF like bcrypt, scrypt, or Argon2 — not a raw hash.
