 ABOUT DIGITAL SIGNATURE CERTIFICATE 





Digital Certificates serve as your identity in the digital world. Just as a passport or a driver's license is used to uniquely identify individuals in the physical world, digital certificates are used to identify entities in digital transactions. Based on Public Key Cryptography, these Digital Certificates associate every entity with a unique pair of credentials - the public key and the private key. Only the owner of a Digital Certificate has access to the private key and can use it to digitally sign and encrypt any digital information such as emails, forms, files etc.

 

A Digital Signature Certificate, like hand written signature, establishes the identity of the sender filing the documents through internet which sender cannot 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.

 

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. 













WHO NEEDS A DIGITAL SIGNATURE CERTIFICATE ?

Under MCA21 Every person who is required to sign manual documents and returns filed with ROC is required to obtain a Digital Signature Certificate (DSC). Accordingly following have to obtain Digital Signature Certificate: 



 1. Directors 


 2. Auditors


 3. Company Secretary - Whether in practice or in job. 

 4. Bank Officials - for Registration and Satisfaction of Charges 

 5. Other Authorized Signatories.

 

 

 WHAT IS e-token ?

 

A Digital Signature certificate (DSC) is kept in internet explorer of computer system (PC) but keeping DSC on your computer system has following draw backs :-

     a) It can be misused by anyone who is having access to your computer system

     b) DSC is lost if computer system is formatted or internet explorer is changed. 

Accordingly, safe and proper method is to keep DSC on e-token, a small USB port devise, which is password protected. The said e-token is a small hardware device and can be plugged to USB port of any system to digitally sign the documents and when not in use can be kept in safe custody.
