The digest recomputes as you edit, with a one-click copy button.

No limits

Hash as much text as you like, free and without an account.

FAQ

Questions & answers

Everything you might wonder about this tool.

01Which algorithm should I use?
SHA-256 is the sensible default for checksums and integrity. SHA-512 produces a longer digest; SHA-1 is provided for legacy compatibility only and should not be used for security.
02Can it hash files?
This tool hashes text input. Paste the content you want to hash; file hashing may be added in future.
03Is any of my data uploaded to a server?
No. This tool runs entirely in your browser with JavaScript — your input never leaves your device, so it is safe to use with private tokens, config and source code.
04Is it free, and do I need an account?
Yes, it is completely free with no signup, no install and no usage limits. Open the page and it works instantly on desktop or mobile.
