What is Digital Signature Certificate(DSC)?

A digital signature is exactly what it sounds like a modern alternative to signing documents with paper and pen.

It uses an advanced mathematical technique to check the authenticity and integrity of digital messages and documents. It guarantees that the contents of a message are not altered in transit and helps us overcome the problem of impersonation and tampering in digital communications.

A digital certificate contains the public key for a digital signature and also specifies the identity associated with the key. Digital certificates are usually issued by trusted authorities and valid for a specified period. The certificate authority will act as the guarantor in the whole process.
