What is DSC AND TYPES OF DIGITAL SIGNATURE CERTIFICATE

 

A Digital Signature Certificate, like hand written signature, establishes the identity of the sender filing the documents through internet which sender can not revoke or deny.

Accordingly, Digital Signature Certificate is a digital equivalent of a hand written signature which has an extra data attached electronically to any message or a document.

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.

A Digital Signature is a method of verifying the authenticity of an electronic document. Digital signatures are going to play an important role in our lives with the gradual electronisation of records and documents.

The IT Act has given legal recognition to digital signature meaning, thereby, that legally it has the same value as handwritten or signed signatures affixed to a document for its verification.

The Information Technology Act, 2000 provides the required legal sanctity to the digital signatures based on asymmetric cryptosystems.

The digital signatures are now accepted at par with handwritten signatures and the electronic documents that have been digitally signed are treated at par with paper documents.

Based on usage the Digital Signature can be categorized into 3 broad categories which are as under :
