Public Key Infrastructure


Public Key Infrastructure

Our last lesson for this chapter on General Cryptography Concepts talks about the Public Key Infrastructure. In this lesson we discuss what the Public Key Infrastructure is and explain each of its sub components and what role they have.

For example, we explored Symmetric and the Public/Private key interrelationship of Asymmetric Encryption in an earlier lesson.  Now we cover Registration Authority, define what a recovery Agent and look other PKI components.

You’ll also learn about Certificates of Authority, how they are generated, what is validate what the certificate revocation list (CRL) is.

And finally, we’ll dissect CA hashing, demonstrate what it looks like during encryption and decryption at the browser level and learn why that is important during the encryption process.
