A Digital Signature Certificate (DSC): What is it?
A digital token issued by a Certifying Authority (CA), such as Emudhra, Capricorn, or Pantasign, that uses cryptographic keys to verify a person’s identity and safeguard the integrity of electronic documents is called a Digital Signature Certificate (DSC). A DSC is required for safe online submissions such as ITR, GST, company registration, e-tenders, and so on, and it has the same legal standing as a handwritten signature.
How Does the Online DSC Application Process Work?
- Speak with a DSC Authorized Agent. These brokers offer a paperless method of purchasing DSCs and could even assist in selecting the appropriate certificate class and validity duration.
- Verify your e-KYC. You must use Aadhaar or PAN-based e-KYC to verify your identity. Supporting documentation may need to be uploaded, verified in person, or verified by video, depending on the option selected.
Typical documents include:
Photo ID: voter ID, passport, or Aadhaar
Proof of address: bank statement, utility bill
The PAN card
A passport-sized photograph
It’s possible that certain CAs will insist on an e-verification via recorded video utilizing the original documents.
Select DSC Validity & Class. Choose the DSC form according to its intended use:
Class 1: Basic validation at the email level.
Class 2: Requires adherence to company regulations or income tax.
Class 3: Required for safe operations like online bidding and tendering
Choose whether the certificate is “Signature only,” “Encryption only,” or “Combo.” Validity options are typically 1, 2, or 3 years.
Complete the online payment.
Choose a secure online payment option, such as a credit card, debit card, net banking, or UPI, after deciding on your DSC type and validity. Rates vary according to issuer, validity, and DSC class.
Verify your identity.
Your selected class and CA may require biometric or video-based identification verification. The DSC is released following successful completion and processing.
Get and download DSC. Following issuance, the DSC can be provided as a USB token or emailed for download via email.
In order to install the certificate on your computer system, tokens frequently include optional middleware software (like eSigner).
How to Register Your DSC (such as Income Tax and GST) on the E-Filing Portal Registering your DSC for usage on official websites:If you haven’t previously, install the eSigner application.
Enter your login information to access the relevant site (e-Filing or GST). On My Profile, select Register/Update DSC.
After selecting your CA provider and certificate, confirm that eSigner is installed, then click Sign.
A confirmation message will be sent to you following a successful validation. If your certificate has been updated or is about to expire, you can also re-register or renew.
Last Thoughts & Advice ✨
DSC validity: Be mindful—renewal is a rerun of the verification and e-KYC process.
Use of certificates:
Class 3 is necessary for high-security operations like tenders, whereas Class 2 is sufficient for most tax and MCA returns.
Security: Keep your token, login PIN, and DSC secure because their unlawful usage raises questions about their legitimacy.
