Today, most businesses and government services are going digital. From income tax filing to company registration, everything can be done online. But how do you sign documents or forms securely on the internet? The answer is simple: by using a Digital Signature Certificate (DSC).
A digital signature online is your identity in digital form. It is safe, secure, and legally valid. If you are a business owner, government contractor, professional, or an individual who regularly works online, you must have a digital signature.
The good news is, that applying for a digital signature is now very easy and can be done online in just a few steps. In this guide, we will explain everything you need to know about how to apply for a digital signature online — without any confusion, paperwork, or agent.
What is a Digital Signature?
A Digital Signature Certificate (DSC) is an electronic version of your signature. It is issued by a licensed certifying authority and used to sign digital documents, applications, and forms.
