X509 and SSL are complicated topics. While they share the basic PKI
infrastructure that PGP and others do, X509 (and SSL by extension) are more
complicated. Extending beyond the basic encryption, signing, decryption, and
verification of basic PKI, X509 includes a variety of extra pieces and
information enabling more features. This talk will cover what X509 and SSL
are, how they relate, how to use them, and how to learn more. It will discuss
PKI from both an certificate end-user perspective as well as from a
Certificate Authority perspective. If time permits, a small comparison to PGP
will also be included akin to the one at the end of my PGP talk.
