Frequently asked questions
Why is MD5 not offered?
MD5 is cryptographically broken and browsers do not implement it natively. SHA-256 is the modern standard.
Are hashes reversible?
No — a hash is a one-way fingerprint. The same input always gives the same hash, but the input cannot be recovered from it.
