Hash Generator

What it does

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text — all four at once, computed locally, nothing sent anywhere. Useful for verifying a file-integrity checksum, building a fingerprint for deduplication, or testing a hashing pipeline during development.

One thing worth being clear about: do not use MD5 or SHA-1 for storing passwords. Both are broken for that purpose — too fast, well-rainbowed, and missing a salt. For password storage use a proper password-hashing function (bcrypt, scrypt, Argon2). See How to hash passwords for the full explanation, and Password Breach Checker if you want to check whether your password has leaked.

How to use it

1. Type or paste your input into the textarea.
2. All four hashes update as you type.
3. Use the Copy button next to any hash.
4. Clear the input when done — nothing is remembered.
