In India, Digital Signature Certificates are issued by Certifying Authorities (CAs) licensed by the Controller of Certifying Authorities (CCA). The CCA regulates the Certifying Authorities under the framework of the Information Technology Act, 2000.

For businesses dealing with online filings, registrations, tenders, tax-related work and other digital processes, understanding DSC types, documents required, cost, application process and uses can help ensure that the appropriate certificate is obtained.

What is a Digital Signature Certificate (DSC)?

A Digital Signature Certificate (DSC) is an electronic certificate that helps establish the identity of the person signing an electronic record. It uses cryptographic technology to authenticate the signer and protect the integrity of the signed document.

Under the Indian legal framework, digital signatures based on asymmetric cryptosystems have legal recognition, and digitally signed electronic documents are treated at par with paper documents in the relevant context.

A DSC generally contains information associated with the certificate holder and is issued after the required identity verification process by a licensed Certifying Authority.

Why is DSC important for businesses?

Businesses increasingly use online platforms for registrations, filings, applications, tenders and compliance activities. A DSC can help businesses:

Digitally sign electronic documents
Authenticate the identity of the signer
Complete certain online applications and filings
Reduce dependency on physical paperwork
Support secure electronic transactions
Facilitate business and regulatory compliance processes

The exact DSC requirements depend on the particular portal, application or transaction.

Types of Digital Signature Certificates

DSCs can differ based on their assurance level, certificate type, purpose and verification method. The CCA’s current framework provides different certificate classes and verification approaches.

Class 1 DSC

Class 1 certificates provide a basic level of assurance and are intended for environments where the risks associated with compromise are comparatively limited.

The current CCA information specifies identity-verification options such as Aadhaar eKYC biometric, paper-based application with supporting documents, or Aadhaar eKYC OTP with video verification, depending on the applicable process.

Class 2 DSC

Class 2 certificates are intended for business personnel and private individuals and provide a higher assurance level than basic certificates.

Under the current CCA framework, the private key for Class 2 certificates is required to be stored in a hardware cryptographic device meeting the specified security requirements.

Class 3 DSC

Class 3 DSC provides a higher assurance level and can be issued to individuals as well as organisations. It is generally relevant to applications where stronger identity assurance is required.

The CCA currently specifies Aadhaar eKYC biometric, paper-based verification with supporting documents and physical appearance or video verification, or Aadhaar eKYC OTP with video verification, depending on the applicable route.

Class 2 vs Class 3 DSC

The appropriate certificate depends on the requirements of the particular application or platform. A higher-assurance Class 3 certificate may be accepted where a lower-assurance certificate is required, subject to the application’s requirements.

DSC Types Based on Purpose

Apart from classes, certificates can also differ according to their intended use.

Some certificates may be issued for:

Individual users
Organisational persons
Document signing
Encryption
System-related purposes
Other specialised applications

The CCA’s India PKI framework recognises certificates for individuals, organisational persons and special purposes such as document signers and encryption certificates.

A Document Signer Certificate should not be confused with the DSC of an authorised signatory. The CCA specifically states that a document signer certificate is intended for software-based automated authenticated responses and is not a replacement for the signature of an organisation’s authorised signatory.

Who Needs a Digital Signature Certificate?

A DSC may be useful or required for various individuals and organisations depending on the online service they are using.

Common users include:

Company directors
Business owners
Partners
Designated partners
Authorised signatories
Professionals
Employees handling online compliance
Organisations participating in online tenders
Businesses using portals that require digital signing

The exact requirement should always be checked against the relevant portal or application because not every business activity requires the same type of DSC.

Documents Required for DSC

The documents required can vary depending on the Certifying Authority, certificate type and verification method selected.

Common information or documents may include:

For Individual Applicants

PAN card
Aadhaar card or other accepted identity proof
Address proof, where required
Mobile number
Email address
Photograph, where applicable
DSC application details

For Organisations

Depending on the certificate and purpose, additional information may be required, such as:

Organisation details
Applicant’s identity proof
PAN details
Authorisation details
Organisation-related documents
Proof of association with the organisation

However, the exact documentation should be confirmed with the selected licensed Certifying Authority because CCA-approved verification routes can include Aadhaar eKYC, paper-based verification, banking eKYC and other permitted methods.

Digital Signature Certificate Cost in India

The cost of a DSC is not a single fixed amount for every applicant.

Pricing can vary depending on:

Certifying Authority
Certificate type
Class or assurance level
Validity period
Crypto token
Additional services
Verification method
Other service-specific charges

The CCA specifically notes that certificates of the same class and type issued by different Certifying Authorities have the same level of assurance and trust, although their prices may vary from one CA to another.

Therefore, businesses should check the current price directly with the selected licensed Certifying Authority rather than relying on an old fixed price.

How to Apply for a Digital Signature Certificate?

The general DSC application process can be explained in the following steps:

Step 1: Identify the DSC Requirement

First, determine why you need the DSC and which portal or application will be using it.

For example, the required certificate may depend on whether you need it for:

Business compliance
Online filing
Tender participation
Tax-related applications
Company-related filings
Other electronic transactions

Step 2: Select a Licensed Certifying Authority

DSCs are issued to end-users by Certifying Authorities licensed by the CCA. The CCA itself does not directly issue DSCs to end-users.

Step 3: Complete the Application

Provide the required personal and/or organisational information and select the appropriate certificate.

Step 4: Complete Identity Verification

The applicant must complete the identity verification process prescribed for the certificate.

Depending on the applicable route, verification may involve Aadhaar eKYC, biometric verification, OTP and video verification, paper-based documentation, or other permitted KYC methods.

Step 5: Complete Payment

Pay the applicable DSC and token/service charges according to the selected Certifying Authority.

Step 6: DSC Issuance

After successful verification and processing, the Certifying Authority issues the Digital Signature Certificate.

Step 7: Install and Use the DSC

Where a hardware crypto token is required, the certificate and private key are used through the prescribed secure device and software environment.

How is DSC Used in Business?

A Digital Signature Certificate for business can be used in several online activities depending on the requirements of the relevant platform.

Common applications include:

Online Compliance and Filings

Certain government and regulatory portals may require authorised users to digitally sign electronic forms or documents.

Company-Related Activities

DSCs may be used by authorised individuals for applicable company-related electronic filings and transactions.

Tax and GST-Related Activities

Depending on the applicable portal and transaction, businesses may need digital signatures for certain tax or GST-related activities.

E-Tendering

Some tender platforms require digital signing and authentication for participation in online tender processes.

Electronic Documents

Businesses can use digital signatures to authenticate applicable electronic documents and transactions.

Secure Business Transactions

Digital signatures can help establish the identity of the signer and protect the integrity of electronically signed records.

The exact use depends on the certificate and the requirements of the relevant application.

Benefits of Digital Signature Certificate for Businesses

A DSC can offer several practical benefits to businesses.

1. Paperless Documentation

Businesses can digitally sign applicable documents without printing, physically signing and scanning them.

2. Authentication

A DSC helps authenticate the identity of the certificate holder.

3. Document Integrity

Digital signature technology helps detect whether the signed electronic record has been altered after signing.

4. Faster Online Processes

Digital signing can simplify applicable online filing and application processes.

5. Convenient Business Operations

Businesses can handle many electronic transactions remotely instead of depending entirely on physical documentation.

6. Support for Compliance

Where a particular portal or process requires DSC-based signing, having an appropriate certificate helps businesses complete the required digital process.

DSC vs Electronic Signature: Are They the Same?

A Digital Signature and an electronic signature are related but should not automatically be treated as identical in every context.

A digital signature uses cryptographic technology and a certificate issued within the applicable PKI framework. The CCA also provides an eSign framework for online electronic signatures using approved infrastructure and identity verification methods.

Therefore, businesses should check whether the particular application requires a DSC, supports eSign, or accepts another electronic-signature method.

How Long is a DSC Valid?

The validity period depends on the certificate issued by the Certifying Authority and the applicable product/service terms.

Businesses should check the validity date of their particular certificate and renew or obtain a new certificate when required.

It is also important to note that the validity of a signature is not simply determined by whether the certificate has expired today. The CCA states that signatures are verified with respect to the time at which the signature was affixed; where the certificate was valid at that time, the signature is deemed valid under the stated framework.

Important Precautions While Using a DSC

A DSC should be handled carefully because the private key is associated with the certificate holder.

Businesses should:

Keep the crypto token secure
Never share the PIN unnecessarily
Avoid giving unauthorised persons access to the DSC
Use the DSC only for authorised transactions
Keep required software updated
Check documents carefully before signing
Revoke the certificate if the private key is compromised
Maintain control of the DSC with the authorised subscriber

The CCA notes that improper protection of the private key can allow it to be misused to sign electronic records without the owner’s knowledge.

For organisational users, the CCA also states that when a subscriber leaves an organisation, the DSC should be revoked and the keys destroyed by the subscriber.
