Secure your email by using a digital signature is an option to make your email more secure. A digital signature isn’t the same as a signature you routinely include with an outgoing message. Anyone can copy an email signature, which essentially is a customizable closing salutation. But your digital signature, which includes your certificate and public key, originates from your digital ID. And that digital ID serves as your unique digital mark and signals the recipient that the content hasn’t been altered in transit.
It seems like a complicated task to make this happens but it is very easy to setup with the following steps:
- Get a digital ID (a cert file from services that issue digital IDs).
- Install certificate file.
- Configuring your email client app, such as Microsoft Outlook.
- Send an email with the signed certificate.
