📋 How to Use

1. Copy the command above
2. Open your terminal and navigate to your project directory
3. Paste and run the command
4. You'll be prompted to enter:
- Keystore password (choose a strong password)
- Key password (can be the same as keystore password)
- Personal details (name, organization, city, state, country code)
5. The keystore file will be created in your current directory

⚠️ Important Security Notes

• Never commit your keystore to Git – Add *.keystore to your .gitignore
• Back up your keystore file – Store it securely in multiple locations
• Save your passwords – Without them, you cannot sign app updates
• If you lose your keystore, you'll need to publish a new app with a different package name

🔧 Using with Capacitor

Add these to your android/key.properties file:

storeFile=../myapp-release.keystore
storePassword=YOUR_KEYSTORE_PASSWORD
keyAlias=myapp
keyPassword=YOUR_KEY_PASSWORD

Then reference this in your android/app/build.gradle signing config.

📦 Prerequisites

The keytool command comes with the Java Development Kit (JDK). If you don't have it installed:

• macOS: brew install openjdk
• Ubuntu/Debian: sudo apt install default-jdk
