FAQ
Is it safe to compute hashes here?
Yes, the hash is computed via the Web Crypto API in your browser; the text is never sent. SHA-1 is outdated for security — for new use choose SHA-256 or SHA-512.
What is a hash for?
To verify data integrity (a fingerprint of a file/text) or as a building block in security. The original text can't be recovered from the hash.
