SHA Hash Generator
Create SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text, computed in your browser so nothing is sent.
- Runs in your browser
- Nothing uploaded
- Free, no sign-up
Generate a cryptographic hash of any text using SHA-1, SHA-256, SHA-384, or SHA-512. Hashing runs entirely in your browser with the built-in Web Crypto API, so your text is never uploaded. Use it to create checksums or verify data integrity.
How to Use SHA Hash Generator
- Enter your text. Type or paste the text you want to hash.
- Choose the algorithm. Pick SHA-1, SHA-256, SHA-384, or SHA-512.
- Generate the hash. Select the button to compute the hash value.
- Copy the result. Use the copy button to grab the hash.
Frequently Asked Questions
What is a SHA hash?
It is a fixed length fingerprint of your input. The same input always gives the same hash, and a tiny change gives a very different one.
Which algorithm should I use?
SHA-256 is a strong, common default. SHA-1 is older and weaker and is best avoided for security.
Can I get the text back from a hash?
No. Hashing is one way by design, so you cannot reverse a hash back into the original text.
Is anything sent to a server?
No. This tool runs entirely in your browser, so the values you enter, including any secrets, never leave your device.
Is it free?
Yes. Every tool here is free to use with no sign up.
