Step 4: Configuring Email Client for Encryption

1. After generating or importing your encryption key, configure your favorite email client, such as Mozilla Thunderbird, to use the key for encrypting outgoing email messages.
2. Ensure that the email client is set to use encryption for all email communications and that the encryption key is properly configured in the client settings.

Step 5: Testing Email Encryption

1. Send a test email message to verify that the encryption is working correctly.
2. Check for a success message indicating that the email was encrypted and sent securely.
