How Hash Generator works
Step 01
Paste your text
Any string — passwords, file contents, seed phrases — anything you need a cryptographic digest of.
Step 02
See all 4 hashes at once
We compute SHA-1, SHA-256, SHA-384 and SHA-512 in parallel using the browser's built-in WebCrypto (crypto.subtle.digest).
Step 03
Copy the one you need
Per-hash copy button. Nothing is uploaded — this is the exact same primitive used by TLS + code signing.
FAQ
Frequently asked
Why isn't MD5 supported?+
MD5 has been broken since 2004 and WebCrypto intentionally omits it. Use SHA-256 or better for anything non-trivial.
Is this fast enough for large text?+
Yes — WebCrypto is hardware-accelerated on every modern device. A megabyte of text hashes in milliseconds.
Are the hashes uploaded anywhere?+
No. Digest calculation happens 100% client-side. The input never leaves your tab.
