Hash Generator
Runs entirely in your browser
Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes directly in your browser.
What is Hash Generator?
Hash Generator computes a fixed-length fingerprint of your text using several common hashing algorithms. The same input always produces the same hash, and even a tiny change in the input produces a completely different one — useful for verifying data integrity or comparing values without storing the original text.
How to use Hash Generator
- Type or paste your text into the Input box.
- Click Generate Hashes.
- Copy any of the MD5, SHA-1, SHA-256, SHA-384 or SHA-512 results.
Features
- Generates MD5, SHA-1, SHA-256, SHA-384 and SHA-512 in one pass.
- SHA-1/256/384/512 use the browser's native Web Crypto API.
- Individual copy buttons for each hash.
- 100% client-side — your text never leaves your browser.
Frequently Asked Questions
Is my text uploaded to a server?
No. All hashes are computed directly in your browser using the Web Crypto API (and a local MD5 implementation). Your text never leaves your device.
Can I use MD5 or SHA-1 to store passwords?
No. MD5 and SHA-1 are fast, general-purpose hashing algorithms — not designed for password storage. Passwords should use a slow, salted algorithm such as bcrypt, scrypt or Argon2, implemented server-side.
Which algorithm should I use?
SHA-256 is a good general-purpose default for checksums and data integrity checks. MD5 and SHA-1 are considered cryptographically broken and should only be used for legacy compatibility, never for security.
Will the same input always produce the same hash?
Yes. Hashing is deterministic — the same input and algorithm always produce the same output, which is why hashes are used to verify file integrity.
