You encrypted your downloadable file for security — great.
But now users need help opening it fast and safely.
Here’s how to let users automatically decrypt files after downloading, with minimal effort.
✅ 1. Encrypt files using 7-Zip or AES tools
-
Use
.zipor.7zwith strong password -
Enable AES-256 encryption
-
Example:
project_data_encrypted.7z
✅ Most users can open it with free tools.
✅ 2. Bundle a decrypt script or instruction
Include a .bat or .sh file:
✅ Auto-extracts when double-clicked.
✅ 3. Use a custom decryption tool (advanced)
Create a lightweight .exe (Python, Electron, etc.) that:
-
Prompts user for password
-
Decrypts and extracts in one click
-
Optionally deletes original
✅ Simplifies the process for non-tech users.
✅ 4. Deliver password via secure method
-
Show password after login or email confirmation
-
Don’t include in the file
-
Optional: rotate passwords weekly
✅ 5. Provide fallback help
Include:
-
README.txt -
Link to 7-Zip
-
Video/gif tutorial
✅ Reduces user support load.
