Hash Generator — MD5, SHA-1, SHA-256, SHA-512
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text instantly in your browser. Free, private, and nothing is uploaded.
How to generate a hash
Choose an algorithm, type your text, and the hash updates instantly. Copy the hex digest with one click.
Hashes are one-way fingerprints used for checksums, integrity checks, and password verification — you can't reverse them back to the original text.
- Pick MD5, SHA-1, SHA-256, SHA-384, or SHA-512
- Type or paste your text
- Copy the resulting hash
Private, in-browser hashing
Hashing runs locally using your browser's native cryptography. Your text and hashes never leave your device.
Frequently Asked Questions
Which hash should I use?
For security, prefer SHA-256 or SHA-512. MD5 and SHA-1 are fast but considered insecure for passwords.
Can a hash be reversed?
No — hashing is one-way. This is why hashes are used for verifying integrity rather than storing readable data.
Is it really client-side?
Yes — everything is computed in your browser using WebCrypto, with nothing uploaded.
