Encrypt a file
Choose files or a folder, set a password, and download the encrypted files plus a key that must stay in the same folder.

Details
Choose one file, several files, or a whole folder. Set a password. The page encrypts each file with AES-256-GCM and downloads the encrypted files plus hash-lock.key. Put the key in the same folder as those files, on this computer or a USB drive. To open them, choose that folder and type the same password. The password is not stored in the key. A lost password cannot be recovered. Tools_On_Tab does not keep the files, the key, or the password.

Limits
A lost password cannot be recovered. The key file does not contain the password. Opening works only when hash-lock.key is in the same folder as the encrypted files. The browser cannot see a USB stick or lock the computer. The optional hint is stored in clear text.

Steps
1. Choose files or a whole folder.
2. Type a password and encrypt.
3. Download the encrypted files and hash-lock.key, or save both into a folder. Keep the key in that same folder.

Questions
How do I open the files?
Choose the folder that contains hash-lock.key and the encrypted files, then type the same password. The key does not open files that are somewhere else.

Is the password inside the key?
No. The key is a separate secret. You still type the password. Tools_On_Tab does not keep either one.

What do I download?
The encrypted files and hash-lock.key. Keep the key in the same folder. There is no separate login database.
