| SummaryA digital signature is not the same as a message signature. A message signature is a customizable greeting. A digital signature, on the other hand, adds a unique code to the message that can only come from the digital signature in the possession of the true sender. (Source: Microsoft.com) With a digital certificate, a message can be protected from tampering and also encrypted end-to-end for even more privacy. A digital certificate, also known as a digital signature, is comparable to an identity card and helps to prove identity on the Internet. |

A certificate is not exchangeable. Mails that have been encrypted with a certificate can only be decrypted again with this certificate. If you lose your previously used certificate, signatures can no longer be verified and encrypted items can no longer be decrypted. Therefore, save it on your home drive or on an encrypted USB stick. Remember your assigned password for the certificate or keep it in a safe place. |
