Questions
Is it safe to encrypt a file online?
Yes, because the file never leaves your device: encryptor encrypts it in your browser, and nothing is uploaded. The server sees neither the file nor the password.
Which file types and sizes can I encrypt?
Any file type works, and its original name and type are encrypted too. There is no size limit in Chrome and Edge, and Safari and Firefox handle files up to 2 GB.
Can I choose my own password?
No, encryptor always generates it: 26 Crockford Base32 characters with 130 bits, plus 2 check characters for typos. That way, every password has a known strength.
How does the recipient decrypt the file?
The recipient opens encryptor.app, chooses Decrypt file, selects the .encrypted file, and enters the password. The original file comes back with its original name.
What if I lose the password?
Then the file cannot be decrypted, not even by us. encryptor does not store the password, so send it over a separate channel and keep a copy somewhere safe.
