A Comprehensive Guide to Public Key Infrastructure (PKI)
PK
In our increasingly digital world, how do we know who we are truly communicating with online? When you enter your credit card information on a shopping website or log into your online bank, how can you be sure your sensitive information is safe from prying eyes? The answer, in large part, is a system called Public Key Infrastructure, or PKI. At a high level, PKI is a framework of policies, standards, and technology that establishes and manages digital trust. It is the silent workhorse of the internet, enabling secure communication, verifying identities, and ensuring the integrity of data for countless daily transactions.
