Digital Certificate: A digital certificate is, more or less, an identification card or you can say an electronic card that confirms or certifies the online transaction as well as another authentication on the internet. We can also refer to a digital certificate as an electronic passport, as it allows an organization or an individual to exchange information over the internet in a secured form using the public key infrastructure (PKI). This digital certificate is commonly referred to as a public key certificate. These certificates authenticate legality of communication and transaction between server and browser or sender and receiver. These certificates also validate surfing sites or portal.

Purpose Of Digital Certificates

Security is the main purpose of these digital certificates. When we work online and log in our details, make a financial transaction, security is the first thing that comes into our mind. To make sure data is transferred securely when the SSL certificate is issued, two keys (Public and private) are issued along with it. The public key is attached along with the electronic message for security purposes. A digital certificate verifies the user, whom she or he is claiming to be and granting the message sent to the receiver along with the public key securely and with a way to encode a reply. The message sent is in encrypted form and once it reaches its destination, the private key is required to decrypt data in readable form. This encryption and decryption of data ensure internet security.
