Hash Generator Guide: SHA-256 & SHA-512 Online

Cryptographic hash generator — illustration

The TetraKits Hash Generator runs entirely in your browser — free, private, and ready on mobile or desktop.

Overview

API signatures, password storage verification, and content checksums all need SHA digests — but installing OpenSSL or writing Node scripts is overkill for a quick check. Paste text, pick an algorithm, and copy the hex hash in seconds.

How to use the hash generator

Enter text and pick SHA-256, SHA-384, SHA-512, or SHA-1 to generate a cryptographic hash digest — results update as you type, all in your browser.

Common use cases

Enter text and pick SHA-256, SHA-384, SHA-512, or SHA-1 to generate a cryptographic hash digest — results update as you type, all in your browser. Bookmark the tool for quick access during projects.

FAQ

Which hash algorithm should I use?

SHA-256 is the default for most applications. Use SHA-512 when you need a longer digest; avoid SHA-1 for security-sensitive work.

Is this the same as encryption?

No. Hashes are one-way fingerprints. Encryption can be reversed with a key; hashes cannot.

Can I hash files?

This tool hashes text input. For file checksums, paste file contents or use a dedicated file hash tool.

Does it use the Web Crypto API?

Yes. Hashing runs locally via the browser SubtleCrypto interface — no server calls.

Is this hash generator free?

Yes. Unlimited hashing with no signup; all processing stays on your device.
