A Digital Signature is nothing but an authentication of any electronic document by a subscriber to the document. Such an authentication is done by the way of an electronic method or process according to Section 3 of The Information Technology Act, 2000.Thus, a Digital Signature Certificate (DSC) is a secure digital key that certifies the identity of the holder. A certifying authority (CA) issues these certificates. Moreover, the DSC comprises of identifying information like an email address and an APNIC account name.

Digital certificates use public key infrastructure for data that has been digitally signed or encrypted by a private key. Moreover, this certificate also works as an authentication that establishes your credentials when conducting business online.

Thus, subject to the provisions of this section, any subscriber can authenticate any electronic document by affixing the Digital Signature on the same.

Just as handwritten signature is used for signing the physical documents, Digital Signature is used to sign electronic records filing such as e-forms (PDF Signing), Income Tax Return, GST Return, ROC Forms, MCA Filing, e-Tender & E-procurement (Signing with Encryption Based), DGFT DSC (With IEC Number), Ice Gate Login, Government DSC, Foreign DSC Etc.
