The Peace Corps is a significant commitment, requiring three months of training in your host country, followed by two years of service at your permanent site. You accrue two days off for every month you work, but the Peace Corps will not pay for your travels.
From Wikipedia, the free encyclopedia. In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate.
The certification authority is the primary component of a PKI. Most PKIs will have more than one CA. A CA is simply a server that runs some sort of certificate services software. An example is the Microsoft Windows 2000 certificate services, which is included with the Windows 2000 server operating systems.
