Why use a digital signature?

Sign your email, documents or software with a digital signature. By doing so, you can prove that a file truly comes from you and prevent anyone else from tampering with it. Digital signatures can also be used to open encrypted email messages, allowing you to exchange data in a secure manner without the risk of your information being intercepted and read by any third parties.
