How Do Digital Signature Certificate work?

Digital signature certification on FilesDNA works on two crucial key pairs; one private key which is to be held by the owner, used for signing and decrypting, and the other is the public key, that is used for encryption of the data send to the general key owner or authentication of the certificate holder’s signed data. Thus, these digital certificates allow the entitles to share their public key in a way that can be authenticated.

Moreover, digital certificates are used in public-key cryptography functions, most commonly used to initialise secure and safe connections between web browsers and web servers. Additionally, they are also used to share keys for public-key encryption and authentication of the digital signature certificate.

Different types of Digital Signature Certificate

Generally, there are three types of free digital signature certificates used by web servers and web browsers:

1. Domain validated

The least amount of assurance about the holder of the certificate is offered by the domain validated certificate. DV certificates can also give confidence that data is being sent and received by the certificate holder, but they don’t guarantee who the entity is.

2. Organization validated

Then there is an organisation-validated certificate that provides additional assurances about the certificate holder after confirming that the applicant has the right to use the domain. Moreover, organisation-validated certificate applicants undergo much further confirmation of their ownership of the field. 

3. Extended validation

Lastly, the extended validation certificate is issued only after the applicant can prove their identity to the satisfaction of the CA. While the evaluating process includes verification of the entity applying for the certificate, thus verifying that identity matches with the records and verifying if the person is authorised to use the domain, and confirming that the domain owner has authorised the issuance of the certificate.
