    How does it work?

    A Digital Signature Certificate (DSC) can be used as a proof of identity to access services over the internet or digitally sign a document. This DSC is secure, ensuring the privacy of any information that you exchange using it. It might be similar to a handwritten signature, but in comparison, it is much more difficult to forge. If well implemented, they provide a layer of validation that helps the receiver to rectify the authenticity of the signature. A signature verifying algorithm is produced that has three levels of algorithm to accept or reject the authenticity. The levels could be labeled as authentication, non-repudiation, and integrity.
    Authentication - Whether the signature was created by a known sender.
    Non-repudiation - To be sure that the sender cannot deny having sent the message.
    Integrity - To be asured the message was not altered in transit.
