Frequently asked questions
Which hash algorithms are supported?+
SHA-1, SHA-256, SHA-384 and SHA-512, computed with the browser's Web Crypto API. MD5 isn't included because browsers don't provide it natively.
Is my text uploaded to hash it?+
No. Hashing happens entirely in your browser using Web Crypto — nothing is sent to a server.
Is SHA-1 safe to use?+
SHA-1 is fine as a checksum but is considered weak for security (collisions are feasible). Prefer SHA-256 or stronger for anything security-related.
Can I hash a password with this?+
You can compute a hash, but a plain SHA is not how you should store passwords — use a slow, salted algorithm like bcrypt or Argon2 for that.
