The name you chose in the previous step (say foo.pli3) is not secure by default. This means that anyone can masquerade as foo.pli3, thus misleading people who want to contact you by this name. In order to avoid this problem, we recommend that you SECURE your name by requesting a certificate for it from the OCALA Certificate Authority. The OCALA proxy presents the certificate to anyone who wishes to verify that they are really talking to foo.pli3.

Please note that users who have security disabled will not bother authenticating you.
