Understanding a Digital Signature Certificate

Digital Signature Certificate

A digital signature is basically a certificate, which the signer of the digital signature attaches to the content, document or resource, in case the signer may have altered or tampered with it. If the signer alters or removes the certificate, the document or resource becomes invalid and becomes a useless copy.

Depending on the type of digital signature certificate, they can prove the truthfulness of the digital signature, and other things. Class 1 certificate is considered the most authentic. Class 2 and Class 3 certificates are a little bit less authentic.

Class 1 digital signature certificate is an electronic version of the physical document, used by establishments, organisations and individuals. An electronic copy of the document, prepared by signing it, does not verify the veracity of the document. The digital signature of an electronic document does not provide a verbal verification or rebuttal of the digital signature.

The digital signature certificate can be rendered either digitally or lithographically. They may also include an electronic seal, which function as a security device and act as a mechanism to give a digital signature for integrity, and to protect the rights of others.

A digital signature certificate can be issued to electronic signatures or they can be issued by typing the document in a box and marking the box with an electronic seal. If there is no signature, the seal is null and void. The following are examples of the digital signature certificates:
