Mozilla and PKI Certifications...

As stated in my previous blog post, SSL (Secure Socket Layer) is meant to enable encrypted data to be transferred over the internet, while PKI (Public key infrastructure) is meant to distribute and verify certificates to users (websites, programs, etc) that signify a legitimate source and secure data. Data sent by SSL that has a PKI certificate is not meant to be inspected by anyone, except for the parties involved in the requests and responses.

Encryption decrypted?...

SSL, TLS, and PKI are very important tools for security on the internet. SSL is an abbreviation for Secure Socket Layer, TLS means Transport Layer Security.

Both of these are application layer encryption protocols. PKI means Public key infrastructure. PKI is a various assortment of implementations, such as software, hardware, and people.  PKI is used mainly to identify and certify legitimate users based on a key that has been assigned. Essentially, PKI uses Certificate and Registration Authorities (CA & RA) to digitally sign the user into the database, and assign a key that is generated pseudo-randomly and encrypted with cryptographic protocols, such as SSL for example.
