What Is a Digital Signature Certificate

Although conducting transactions online is easier and more convenient, it’s also more prone to fraudulent activities. One way to reduce the risk of fraud is by using Digital Signature Certificates for all the paperwork you process digitally.

So what is it? A DSC is an electronic document that serves as proof of identity for an individual or organization. This document contains the identity information of the certificate holder and a public key that can be used to verify the signature on a digital document. Think of it as an ID to prove that it’s your digital signature you’re affixing to any legal document.

The process of obtaining your own DSC is actually pretty straightforward. Here’s how to get yours:

  1. Select a Certifying Authority (CA) in your area duly authorized by your government.
  2. Prove your identity by submitting the necessary documents containing your personal information.

After the identity verification process, you will receive your certificate, which will be saved on a USB. It’s important to note that DSCs have a validity period and need to be renewed before they expire.

You will need a program compatible with the DSC to sign any document. This program will require you to insert the USB token and then ask you to enter your identification number. Once you’re in, you can access your DSC.

The Different Types of Digital Signature Certificates

There are several types of Digital Signature Certificates available, each with its use case and level of security. The most common types of DSCs include:

Class 2

Class 2 DSCs are used for transactions that require a moderate level of protection. They are typically used for transactions such as e-filing of income tax returns and registering for various government services.

Class 3

If you deal with highly sensitive online transactions, you might want to look into obtaining Class 3 DSCs. These digital signature certificates are typically used for e-tendering, e-procurement, and other critical transactions that require strong authentication and non-repudiation.

Directorate General of Foreign Trade (DGFT)

DGFT DSCs are used for import-export-related transactions. They are used for authenticating and signing export and import-related documents and obtaining licenses and permits from the DGFT.


Organizational DSCs are issued to businesses or institutions for authorized employees to sign the documents electronically.

Signing only

As the name suggests, signing-only DSCs are used for the primary purpose of signing documents online. This doesn’t include encryption.

Encryption only

Conversely, you may also choose to obtain an encryption-only DSC, which you can use exclusively for keeping your confidential documents secured.

Important Note: When selecting a particular DSC for your organization, it’s best to check with your corresponding CA as the types vary per country.

The Importance of Digital Signature Certificates

Now that you know what a DSC is and its different types, let’s explore why obtaining one for your organization is essential.

1. Legal Recognition

Digital Signature Certificates are legally recognized and accepted in many countries all around the globe. You can use them to sign legally binding documents such as contracts, agreements, and government forms. It is required to obtain a DSC to use digital signatures in a legally binding way.

2. Compliance

DSCs can be used to meet compliance requirements for various industries and government regulations. Many businesses are required to use DSCs for legal and financial transactions, and failure to do so can result in penalties.

3. Identity Verification

One of the main purposes of DSCs is to verify the identity of an individual or organization. This helps to ensure that the person or entity signing the document is who they claim to be and helps to prevent fraud and other security threats.

4. Non-repudiation

DSCs provide non-repudiation, which means that the person or entity that signed the document cannot deny that they signed it. This is important in legal and financial transactions where the signer’s identity is crucial.

5. E-Governance

Various online government transactions, including e-tendering, e-procurement, and e-filing of taxes, require DSCs. If you are leaning towards processing these things digitally, you need to obtain a certificate for a smooth transaction.

6. Secure Communication

Digital Signature Certificates are valuable to any business because they can be used to secure communication between organizations and their customers, partners, and other stakeholders. They provide a higher security level than traditional, paper-based signatures, making it harder for unauthorized parties to access or tamper with the information.

7. Convenience

While signing documents digitally is easy, the process of verifying the authenticity of the signature can be tedious if you don’t have the right tools. With DSCs, you can skip the long and winded verification process.

8. Cost-effective

Aside from saving you time, DSCs can also help reduce your operational costs. There’s no need to spend a considerable amount of money on printing, mailing, and storing paper documents. Moreover, you can also save big bucks on in-person meetings and travel for signing.

In summary, DSCs provide a secure and legally recognized means of verifying the identity of individuals and organizations and ensuring the authenticity and integrity of electronic documents. They are a vital tool for businesses looking to protect their online transactions and ensure compliance with regulations.
