CryEnv 🔐 - Secure .env Surveys for Teams

Effortlessly collect & manage missing .env variables in a secure way.

🔹 What is CryEnv?

CryEnv is a CLI tool that helps teams securely collect missing environment variables by creating interactive encrypted surveys.

With CryEnv, you can:

• Detect missing .env variables in your project.
• Create encrypted surveys to request missing values.
• Securely share a survey token with a team member.
• Import responses back into your .env file.
• Ensure only the creator can decrypt responses.

✅ Fast.
🔐 Secure.
🛠️ Easy to use.

🔒 Security & Data Handling

CryEnv is designed with security and privacy in mind. Here’s how data is handled:

Questions (Unencrypted)

• Questions are not encrypted and are stored in base64 format with zlib compression.
• Do not include sensitive data in questions. Use them only to describe what information is needed.
• Questions are used to guide the recipient and are not considered secret.

Answers (Encrypted)

• Answers are fully encrypted using a combination of AES-256-CBC and RSA:
  1. Compressed with zlib.
  2. Encrypted with a randomly generated AES-256 key.
  3. The AES key is encrypted using the creator’s RSA public key.
  4. The final payload is encoded in base64 for easy sharing.
• Only the survey creator can decrypt the answers using their private key.

Email Feature (Optional)

• CryEnv can send survey links via email using node-fetch and a private server at webto.pro.
• No sensitive data is sent or stored on the server. Only the encrypted survey token is transmitted.
• Emails are used solely for convenience and are not required. You can share tokens manually.

Guarantees

• No data is stored on external servers.
• Emails are not saved or shared with third parties.
• The email feature is optional and can be skipped if you prefer manual sharing.

🚀 Quick Start

No installation required! Just use npx:

npx cryenv

This will guide you through creating an encrypted survey for missing environment variables.

To fill a survey:

npx cryenv --fill YOUR_TOKEN

To import responses into your .env file:

npx cryenv --import YOUR_TOKEN --path=.env

🔍 How It Works?

1️⃣ Create a survey with missing .env keys.
2️⃣ Share the generated token with a teammate.
3️⃣ The recipient fills the survey via CLI.
4️⃣ Responses are securely encrypted – only you can decrypt them.
5️⃣ Import the responses directly into your .env file.

🔒 All data remains private & secure – even CryEnv cannot read the responses.

📦 Installation (Optional)

You can install CryEnv globally:

npm install -g cryenv

Now you can use it without npx:

cryenv

🛠️ Commands & Usage

1️⃣ Detect missing .env variables

Automatically scan your .env.example or another file:

npx cryenv --env .env.example

This will create a survey with all missing variables.

2️⃣ Create a new survey

npx cryenv

You'll be guided through an interactive setup.

3️⃣ Fill a survey (as a recipient)

If someone shares a CryEnv token with you, fill it like this:

npx cryenv --fill YOUR_TOKEN

You'll be prompted to enter values.

4️⃣ Import responses into .env

npx cryenv --import YOUR_TOKEN --path=.env

This will decrypt responses and add them to your .env file.

5️⃣ Restore a saved survey

npx cryenv --restore FILE

Useful if you need to re-import or review responses.

🔐 How CryEnv Ensures Security?

✔ All responses are encrypted.
✔ Only the survey creator can decrypt responses.
✔ Survey tokens never expose raw data.
✔ No external servers are used – works fully offline.

💡 Example Workflow

Imagine you're working on a team project. Some environment variables are missing, and you need your teammate to fill them securely.

1. You create a survey and get a unique token:

   npx cryenv --env .env.example

2. You share the token with a teammate:

   npx cryenv --fill YOUR_TOKEN

3. They fill the survey without seeing other values.

4. You import their encrypted responses into .env:

   npx cryenv --import YOUR_TOKEN --path=.env

🎉 Done! Your .env file is now complete – securely.
