FAQ
What is the difference between hashing and encryption?
Hashing is one-way and cannot be reversed. Encryption can be reversed (decrypted) with a key.
Is MD5 secure?
No. MD5 has known collision attacks and is not recommended for security. Prefer SHA-256 or stronger.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
