![]() Messages can be encrypted using different keys, which means that even if they are intercepted through an insecure channel, they cannot be opened or tampered with. Certificate-based digital ID is used for encrypting and decrypting the message itself, so the only one who can open it is the person or entity you sent it to. A digital signature comprises unique characters in the body of a message or at the end of a document that essentially “locks” it and certifies its validity.ĭigital signatures are based on public key infrastructure (PKI) or cryptographic operations. Recipients of the document can verify the sender’s identity, detect message tampering and spoofing, and establish its authenticity. ![]() What Is a Digital Signature?Ī digital signature is a mathematical mechanism that allows you to sign an electronic document. This article discusses the differences between electronic and digital signatures, such as their unique purpose and how they are created. Have you ever wondered what the difference between electronic and digital signatures is? Electronic signatures are easy to acquire, convenient, and, most importantly, legally binding. Today, you can sign any contract, agreement, or document from anywhere in the world with any device you have. Gone are the days when the only way to sign a document was to put pen to physical paper and send it off via fax machine or snail mail.
