%X CA (certificate authority) is a critical component in PKI. When the private key of a CA is compromised, all the certificates issued by that CA should be revoked. Keeping the private key secret while providing service on line is very important for a CA. Rather than prevent intrusions or detect them after the fact, the project ensures that the compromise of a few system components does not compromise the private key of the CA. The private key is protected by distributing it across a few servers. The private key is never reconstructed at a single online location.
