Type or paste your text, then pick SHA-1, SHA-256, SHA-384, or SHA-512; the digest updates live below as you type.
The result renders as a lowercase hex string, with a Copy button next to it so you can grab the digest without selecting the text by hand. Nothing you type here is stored beyond this page session, sent to any analytics or tracking service, or tied to an account - there is no signup at all.
Hash Generator (SHA-256/512)
Paste text into Hash Generator and get a lowercase hex digest from the browser's WebCrypto API - SHA-256 is the default, with SHA-1, SHA-384, and SHA-512 available in the same dropdown.
Hashing runs entirely on your device via crypto.subtle.digest - nothing you type is uploaded. Copy the hex result with one click. MD5 is not offered here because modern browsers omit it as insecure; use the related MD5 Converter when you specifically need MD5.
Nothing you type is stored beyond this page session, sent to any analytics or tracking service, or tied to an account - there is no signup required.
For identifiers instead of digests, try the UUID Generator. When you need a walkthrough of the SHA options, see the Hash Generator step-by-step guide or compare options in the vs alternatives guide.
