To encrypt an email attachment, you can use software like 7-Zip or WinRAR to first compress and encrypt the document before sending. Choose AES-256 encryption during the compression process, ensuring to set a strong password. Once encrypted and compressed, attach the file to your email. Remember, you’ll need to share the password with the recipient separately—never through email. For added security, consider using encrypted email services like ProtonMail or encrypted messaging apps to transmit the password.
