How to use

Enter Text and Algorithm into SHA-256 / SHA-512 and press Run — or just type, live results update as you edit. GenForge computes the answer instantly with a pure JavaScript engine (Web Worker for heavy inputs) on this page. Nothing is sent anywhere: no signup, no server round-trip, same inputs always give same outputs.

FAQ

Is SHA-256 / SHA-512 really free?

Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.

Is anything I type into SHA-256 / SHA-512 sent to a server?

No. Every keystroke is computed with a pure JavaScript engine (Web Worker for heavy inputs) inside this page. Close the tab and your data is gone — unless you explicitly download or share it.

What should I enter in "Text"?

Put your text here — for example: hello. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.

I normally use QRTiger — why switch?

If you are tired of signup walls for high-resolution downloads and generators that log what you create, GenForge is the alternative: WebCrypto secrets, nothing logged or stored, one-tap copy and download.

How accurate is SHA-256 / SHA-512?

Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
