In today’s fast-moving digital world, most documents are shared and signed online. But how do we know if a document is real or has been changed? That’s where digital signatures become important. They help to protect documents, verify the identity of the signer, and build trust between people doing business online.
In this article, we’ll explain what digital signatures are, how they work, and their main purposes. You’ll also learn why digital signatures are used, how they add security, and how you can create your free signature using Sign Well, without any registration.
What is a Digital Signature and How Does It Work?
A digital signature is like an online version of your handwritten signature. But it’s much more secure. It is created using mathematical algorithms and encryption techniques that protect your identity and the document.
How Digital Signatures Work – Explained Simply
Here’s a simple way to understand how digital signatures work:
A person signs a document using a private key (a special code only they know).
The digital signature is added to the document.
The person receiving the document uses the public key (a code shared with others) to check if the signature is real.
If the signature matches and the document hasn’t been changed, it is considered safe and valid.
This system makes sure the signature is unique and that the document cannot be changed after signing.
Which of the Following is a Primary Purpose of Using a Digital Signature?
There are many reasons to use digital signatures. Let’s look at the main purposes:
1. Authentication
A digital signature proves that the person who signed the document is really who they say they are. This helps avoid fraud and builds trust.
2. Data Integrity
Once a document is signed digitally, it cannot be changed without making the signature invalid. This means the document stays exactly as it was when signed.
3. Non-Repudiation
Once someone signs a document digitally, they cannot deny signing it later. This is helpful for legal and business reasons.
4. Time-Stamping
Digital signatures often include the date and time of the signature. This shows when the document was signed and is useful for records.
In short, the main purpose of using a digital signature is to secure the document, prove the identity of the signer, and ensure no changes were made after signing.
