DSC

Digital Signature certificate

There are three types of DSCs Class I type is used only for securing email communication

Class II type is used for Company or LLP Incorporation, IT Return E-Filing, obtaining DIN or DPIN and filing other forms with the Ministry of Corporate Affairs and Income Tax Department

Class III type is used mainly for E-Tendering and for participating in E-Auctions

For most business compliance, Class II digital signature suffices.
