CACert
Booth: #15

CAcert.org is a community driven, Certificate Authority that issues certificates to the public at large for free.
CAcert's goal is to promote awareness and education on computer security through the use of encryption, specifically with the X.509 family of standards. We have compiled a document base that has helpful hints and tips on setting up encryption with common software, and general information about Public Key Infrastructures (PKI).
