SHA-256 Hash Generator
Compute the SHA-256 digest of any text using the browser's native Web Crypto API, giving you a 64-character hex hash that updates as you type. Because it runs locally, your input is never uploaded.
- 100% free
- Private & safe
- Runs in your browser
Why use SHA-256 Hash Generator?
SHA-256 Hash Generator runs locally using your browser's built-in cryptography, so passwords, keys and hashes are never uploaded or logged.
- Runs instantly in your browser — nothing to install, nothing uploaded.
- Completely free, with no account, no watermarks and no usage limits.
- SHA-256 (256-bit, 64 hex characters)
- Type or paste the text you want to hash.
- Works on any device — desktop, tablet and phone — and is fully keyboard accessible.
How to use SHA-256 Hash Generator
- Type or paste the text you want to hash.
- The SHA-256 hash appears instantly below.
- Copy the 64-character hexadecimal digest.
- Clear to hash something else.

- Generating a deterministic id from a string.
Supported formats & limits
- SHA-256 (256-bit, 64 hex characters)
Limitations
- Hashing is one-way; you cannot recover the original text from the hash.
- This hashes text; for files, use a dedicated file-hashing tool.
Frequently asked questions
Is SHA-256 reversible?
No. It is a one-way function; the original text cannot be derived from the hash.
Where is the hashing done?
Locally, using your browser's Web Crypto API — nothing is uploaded.
Is it suitable for passwords?
For password storage, use a slow, salted algorithm like bcrypt/argon2 on a server, not a raw hash.
