How to use the hash generator
- Choose SHA-256, SHA-384, or SHA-512.
- Paste or type the text you want to hash.
- Press Generate hash to create a hexadecimal digest.
- Remember that hashing is not encryption and a raw digest is not a password storage design.
Common uses
Create a quick SHA-256 digest for a text sample.
Compare whether two pasted text values produce the same digest.
Generate SHA-384 or SHA-512 outputs for learning and debugging.
Keep small text hashing local in the browser.
Examples
96-character hex digest
128-character hex digest
Frequently asked questions
Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
When should I use the Hash Generator?
Use it when your task matches one of these common needs: Create a quick SHA-256 digest for a text sample. Compare whether two pasted text values produce the same digest. It works best when you already know the values, dates, units, or settings the page asks for.
What is the Hash Generator doing with my inputs?
In plain language: The tool encodes text as UTF-8 bytes, passes those bytes to browser SubtleCrypto for the selected SHA-2 digest, and formats digest bytes as hex. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
What should I double-check before trusting the answer?
A hash is not encryption. Do not use a raw digest as a password storage design, signature system, or proof of authenticity. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.
Does the site save what I enter?
No. The calculator runs in your browser tab. Your recent answers stay only on the page while you use it, and they are not sent to a server.
