Most users are unaware of the types of operations which perform in the background when they open applications and access various resources, including PKI. For them, all they are required to do is to supply their user ID and password. What they will not see are processes which are used to secure and encrypt data sent over a network or the internet. Instead, these processes are handled unseen and automatically by their computers.
Encrypt Data Sent Over Unsecure Networks by Using PKI
PKI has to do with public key infrastructure and was created as a means to secure data sent over public networks, including the internet. Public networks and the internet are not secure connections. Any data sent without first being encrypted can be accessed by another person with the knowledge and ability to obtain it. Encrypting data before it is transmitted is often handled using digital certificates contained on the user’s computer.
