FAQ
Is the MD5 hash secure?
No. MD5 is a fingerprint algorithm, not a security primitive. Use SHA-256 or stronger for any security-sensitive work.
Are hashes sent to a server?
No. Every algorithm runs locally in your browser using crypto.subtle (or a small MD5 routine) without any network round-trip.
