Creating a Digital Signature in Word: A Step-by-Step Guide

A digital signature ensures the integrity and non-repudiation of documents. By attaching a digital signature to your Word documents, you can verify their authenticity and protect them from unauthorized modifications.

What is a Digital Signature?

A digital signature is a cryptographic technique that binds a person's identity to the content of a document. It guarantees the document's integrity, meaning any changes made to the file after signing will be detectable. It provides a higher level of security and confidence compared to traditional ink and electronic signatures. 

How to Make a Digital Signature Official?

To make your digital signature official and recognized, you need to obtain a digital certificate from a trusted certificate authority (CA).

A digital certificate contains your public key and other identifying information, such as your name, email address, and organization. The CA vouches for your identity by digitally signing your certificate, lending credibility to your digital signature.

What Does a Digital Signature Guarantee?

1. Authenticity: A digital signature proves the signer is genuine, and that the document has not been altered or tampered with since signing.
2. Integrity: Any modifications made to a digitally signed document after the signature will invalidate the signature.
3. Non-repudiation: With a digital signature, the signer cannot deny their involvement or claim forgery of the signature. It strengthens accountability and legal enforceability.
