Digital Signature Certificate - How DSC Works

Nowadays, when everything is authenticated online, Digital Signature Certificate (DSC) is another way of verifying the identity of the document holder.

We are required to sign the documents in order to verify our identity.

Nowadays, with everything moving online, it's more important than ever to be able to validate your identity. Whether it's for online activities like shopping, banking, or social media, or computer-based work, you need a way to prove that you are who you say you are.

That's where a Digital Signature Certificate (DSC) comes in handy. It's a secure way to authenticate your identity online, so you can conduct transactions with confidence.

What is Digital Signature Certificate (DSC)?

A Digital Signature Certificate (DSC) is nothing but a signature in an electronic format, which is similar to a physical signature. It is used for different types of online transactions. A Digital Signature Certificate (DSC) is a protected digital key that is issued to validate the identity of the certificate holder by recognizing certifying authorities (CAs). It includes the name of the individual, the digital signature, the date of issuance of the certificate, the expiry date, and the name of the CA.

How Digital Signature Works ?

A digital signature is like a handwritten signature that is unique to each signer. It works by ensuring that documents that have been digitally signed have not been tampered with or altered by any other third-party user, intentionally or unintentionally.

When a signer signs a document electronically, the signature is created using the private key of the signer, which is always kept by the signer securely. The mathematical algorithm creates, and encrypts data that matches the signed document, called a hash, acting like a cipher.

The digital signature is the resulting encrypted data. The signature is also marked with the signing time of the document. The digital signature certificate (DSC) is invalidated if the document changes after signing.
