It ensures that the document is genuine, the identity of the person signing is verified, and the document is protected from tampering.
In this guide, we’ll explain everything you need to know about Class 3 Digital Signatures, including what they are, how they work, and how to use them to protect your important documents. By the end, you’ll understand why Class 3 Digital Signatures are essential for securing your documents and how to easily obtain and use one.
What is a Class 3 Digital Signature?
A Class 3 Digital Signature is a highly secure electronic signature used to authenticate the identity of the person or business signing a digital document. It’s considered the most trusted level of digital signature certification because it requires the person or organization to go through a rigorous identity verification process. This ensures that the signature is legitimate and can be used for critical and sensitive online transactions, such as e-tendering, e-filing of legal documents, and signing contracts.
The signature is created using a secure digital key (also known as a private key), which is unique to the person or organization. The key is stored in a hardware device like a USB token to ensure the highest level of security. The digital signature acts as a fingerprint, uniquely linking the signature to the signer and protecting the document from tampering.
Why is a Class 3 Digital Signature Important?
Here are some reasons why Class 3 Digital Signatures are important for protecting your documents:
Security: A Class 3 Digital Signature provides the highest level of security for online transactions and document signing. It ensures that the signer is authenticated and that the document hasn’t been altered after being signed.
Legally Binding: Digital signatures are legally recognized in many countries, including India, under the Information Technology Act, of 2000. A Class 3 Digital Signature can be used for legal documents, contracts, and official government filings, assuring that the signature is valid and enforceable in court.
Tamper-Proof: Once a document is signed using a Class 3 Digital Signature, it is sealed with an electronic code. This code makes it impossible for anyone to alter or tamper with the document without the signature becoming invalid. This ensures the integrity of your documents.
Time-Saving and Convenient: Using a digital signature means you no longer have to physically sign documents or be present to sign important contracts. You can sign a document from anywhere in the world, saving time and making the process more efficient.
Environmentally Friendly: Digital signatures help reduce the use of paper since all documents can be signed and shared electronically. This reduces the need for printing and mailing physical copies, which is also more cost-effective.
