Digital times mean that authenticity and security in documents are something really crucial. A digital signature acts as a virtual fingerprint to safely sign documents electronically with less effort. It’s one thing you should know for all your professional, educational, and business needs. This guide takes you through each step you need to understand creating a digital signature.

What Is a Digital Signature?

A digital signature is an encrypted electronic signature used to authenticate the origin of a digital document or message. The technology relies on public key infrastructure (PKI) and delivers the following benefits:

  • Authentication: It verifies the identity of the signer.
  • Integrity: Ensures that the contents have not been changed.
  • Non-repudiation: Eliminates the possibility that the signer may deny their own signature.

Why Use a Digital Signature?

  1. Time-Efficiency: Avoid printing, signing, and scanning.
  2. Cost-Effective: Reduce spending on paper and ink.
  3. Environmentally Friendly: Avoid printing on paper.
  4. Legal Validity: Acknowledged in many states to be the same as a physical signature.
