Introduction to digital certificates

A digital certificate is a digital document that verifies the identity of an entity (such as a website, server, or individual) and provides a means for secure communication by encrypting data exchanged between the user's device and the entity's server.

They play a crucial role in ensuring the confidentiality, integrity, and authenticity of data transmitted over the internet. 

Digital certificates function through the use of public-private key pairs.

To obtain a digital certificate, an individual or organization must prove their to the certification authority.
