    Digital Signature certificate

    Just as a handwritten signature is affixed to a printed letter for verification that the letter originated from its purported sender, digital signature performs the same task for an electronic message. A digital signature is an encrypted version of a message digest, attached together with a message.

    A secure digital signature system consists of two parts:
    • A method of signing a document such that forgery is detected, and
    • A method of verifying that a signature was actually generated by whomever it represents.

    Digital Signature also ensures that no alterations are made to the data once the document has been digitally signed. A DSC is normally valid for 1 or 2 years, after which it can be renewed.
