What encrypting a file does
The file is scrambled with your password. Without the password, what is left is unreadable.
If you forget the password, the file cannot be recovered. Keep it somewhere safe.
What makes a strong password
The encryption is strong; the password is the part you control.
| Password | Strength | Why |
|---|---|---|
| A name, a date or a common word | Weak | Easy to guess. |
| 8 random characters | Fair | Fine for low-risk files. |
| 12 or more random characters | Strong | Keep it in a password manager. |
| Four or more unrelated words | Strong | Long and memorable. |
What goes in, what comes out
| File | As input | As output | Notes |
|---|---|---|---|
| Documents, photos, videos, ZIP files | Yes | — | Any file can be encrypted. |
| .enc file | — | Yes | The encrypted version, to download. |
| Decrypting | Yes | Yes | Open the .enc file here with the same password. |
