We live in a time where almost everything is online from business contracts to daily emails. That also means cybercriminals have more opportunities to trick people with fake or altered information. This is why it’s important to know how to create digital signature, because it helps stop such threats by proving what’s real and what’s not.

How to Create Digital Signature & Why It Matters in Cybersecurity

Trust and security are essential for protecting your confidential data. And a digital signature is one of them. In this blog we are going to talk about how to create digital signature, as it is very useful for multiple purposes. From signing contracts online to sending confidential emails, everything relies on authenticity. This is where the digital signature steps in. It’s not just a tech tool anymore; it’s a necessity for professionals, businesses, and even individuals dealing with sensitive information. Many users want to know what is email digital signature and its importance. Let us see how to create digital signature easily. 

What Is Digital Signature?

A digital signature is an electronic way of proving identity and securing data. Think of it as a modern stamp of approval, created with cryptography. It confirms two things:

• The document, file, or message truly came from you.
• It wasn’t altered or tampered with during transmission.

Unlike handwritten signatures, a digital signature is unique, encrypted, and extremely difficult to forge. This makes it legally valid in most countries for e-filings, contracts, and business communication.

What Is Email Digital Signature?

An email digital signature is specifically designed to secure your emails. It validates the sender’s identity and ensures the content stays intact, preventing email spoofing, fraud, and phishing attacks.

How to Create Digital Signature

One of the most frequently searched queries is how to create a digital signature, and the good news is that it’s simple! Here’s how:

1. Get a Digital Signature Certificate (DSC): Purchase from a trusted Certificate Authority (CA) like eMudhra, DigiCert, or GlobalSign.
2. Install the Certificate: Add it to your email client, browser, or system.
3. Use Tools for Signing: Applications like Outlook, Gmail (with plugins), Adobe Acrobat, or DocuSign allow you to digitally sign documents and emails.
4. Start Sending Signed Content: Once enabled, your emails and files carry a verified seal of trust.
   

This process ensures authenticity and saves time compared to manual paperwork.

Digital Signature Price

The digital signature price isn’t the same everywhere it changes based on the type of certificate and the provider. Some basic options, like S/MIME certificates, are even available for free. But if you need a business-grade DSC, expect the cost to be anywhere between ₹500 and ₹5000 per year. When you look at the level of security it brings, the cost is quite small. That’s why it’s worth knowing how to create digital signature and start using it for your important files and emails.
