How does a Digital Signature Certificate work?

The generation of a digital signature through legal means necessitates the authentication of personal information of the signer, and this process is achieved by a digital signature certificate. A digital signature certificate is a file that is used to secure the identity of an individual or an organization.

RSA algorithm produces a list of unsystematic hash worth relating to the open key and the secret key. Public key assists in confirming the identity of the user that is safely stored in a digital signature certificate and the generation of the digital signature is done by the use of the private key. Only the signer is aware of the private key. A digital signature certificate binds the identity of the private key which may be the name of the organization or an individual. A digital signature certificate will include the name and identification number of a user, a copy of the user public key (which will be used to decrypt the message), and a digital signature of Certifying Authority (CA).
