PeerGFS employs TLS encryption to secure data transmission between the PMC, Agents, and brokers, as well as for accessing the PMC web user interface and API service.  TLS utilizes keys and certificates to authenticate hosts and encrypt data.  The deployment of PeerGFS includes default certificates.  If preferred, you can update some or all of these certificates with new ones that are either self-signed or signed by a Certificate Authority (CA).

PeerGFS now ships with a set of utility scripts to simplify the generation and replacement of TLS certificates. More details on how to use these scripts can be found here.
