What is a Digital Signature Certificate (DSC)?
The Information Technology Act, 2000 provides for use of Digital Signatures on the documents submitted in electronic form in order to ensure the security and authenticity of the documents filed electronically. This is the only secure and authentic way that a document can be submitted electronically. As such, all filings done by the companies under MCA21 e-Governance programme are required to be filed with the use of Digital Signatures by the person authorised to sign the documents.
You can use only the valid Digital Signatures issued to you. It is illegal to use Digital Signatures of anybody other than the one to whom it is issued.
Certification Agencies are appointed by the office of the Controller of Certification Agencies (CCA) under the provisions of IT Act, 2000. There are a total of seven Certification Agencies authorised by the CCA to issue the Digital Signature Certificates (DSCs). The details of these Certification Agencies are available on the portal of the Ministry www.mca.gov.in
Class of DSCs:
The Ministry of Corporate Affairs has stipulated a Class-II or above category certificate for e-filings under MCA21. A person who already has the specified DSC for any other application can use the same for filings under MCA21 and is not required to obtain a fresh DSC.
Validity of Digital Signatures:
The DSCs are typically issued with one year validity and two year validity. These are renewable on expiry of the period of initial issue.
