Part 1. What is Digital Signature, and Why is It Important?

In simple words, a digital signature is an electronic form of signature used to confirm the authenticity and integrity of a digital document. The digital signature validates that the information is originated from the signer and is not altered. It ensures end-to-end integrity by using a mathematical algorithm that validates the transparency of digital content.

One of the most crucial benefits of a digital signature is ensuring the signer's identity. It is based on public-key cryptography, which eradicates the chances of manipulating the signature. Moreover, electronic signatures are easily signed and verified, thereby reducing the time and cost linked with printing, signing, scanning, and sending paper documents. In short, a digital signature is an effective way to ensure the authenticity and integrity of the document.
