Document Digital Signatures

Digital signatures

Digital Signatures are just like electronic fingerprints. It is like a coded message. This concept provides high-level security. Digital Signatures use a format called Public Key Infrastructure. It is a collection of requirements that help in the creation of digital signatures.

Hand-written signatures are unique to every person. In the same way, digital signatures are also unique. In this article, we are going to provide you a piece of brief information about digital signatures.

Why use digital signatures

Digital signatures are much more powerful than paper-based signatures. They provide users a fast and secure way to sign the documents. You can also use the commands for copying and printing the documents. CTRL+C copies the content. CTRL+P prints the document.

Digital signatures lock down the document. We cannot do any changes to the document. Any changes done after the signature is done invalidates the document. To sign any document digitally, a digital certificate is mandatory. You can also add one or more than one signatures.

What are digital certificates

Another name for a digital certificate is the public key certificate. Digital certificates are provided by the certificate authorities. Certificate authorities are some trusted agencies just like passport offices. They can be either private or government institutions.

So, they are more secure. These certificates are in use by many web browsers. There are three types of digital certificates. It is an equivalent of an identity card. Online Baking would not be possible without these certificates.

Digital certificates ensure essential variables of trust. By using PKI, the digital signature includes a pair of keys: a private key and a public key. The private key is not shared or copied by anybody and is used only by the signer to sign the documents. The public key is available and used by the people who need to validate the signature.

These signatures are valid for a certain time. Digital signatures increase the speed of the verification and reduce the consumption of paper. They help in the conservation of nature.

Advantages of digital signatures

  • Add security: They provide more security than an electronic signature. An algorithm embedded in the software to encrypt the data. Each signature provides a date stamp and timing. They also hold validity in the future.
  • Globally Accepted: Many countries all over the world accept these digital signatures. They offer us independent verification. No authority has the right to alter this verification of the signatures. It is in use of both small- and large-scale organizations.
