Online signing of documents has become common in today’s digital world. However, how can someone confirm that the signature is real? A Digital Signature Certificate (DSC) can help with that. It confirms that the file has not been changed and helps in proving who signed a document.
When you sign or send digital documents, a Digital Signature Certificate verifies your identity online, similar to an identity card.

A Digital Signature Certificate is an electronic key issued by the government-approved authorities. It verifies the genuineness of the person signing an online document. To put it simply, a DSC is similar to a digital ID card that verifies your identity in each online transaction.
It includes the following information,
