Free tool No accountHash Generator (SHA)
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes in your browser.
About the Hash Generator (SHA)
Create SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text, to check that a file or message hasn't changed or to compare values without showing them.
How to use it
- Paste the text.
- See every hash at once.
- Copy the one you need.
Tip: Hashes are one-way: you can't get the text back from a hash. For storing passwords, use a slow password hash such as bcrypt or Argon2 on your server.
Questions
Which hash should I use?
SHA-256 for most checks today. SHA-1 is only for old systems that need it.
Is my data uploaded?
No. The tool runs in your browser; what you paste or open never leaves your device and nothing is stored on a server.
