This directory contains an already generated TLS certificate that can be used in your OpenSIPS configuration. It's a generic certificate with the main purpose of serving as example and for testings. IMPORTANT: it's not a trustable certificate - the CA is also an example. All TLS configuration file may be found in "user" directory. If you want to generate your own certificate, you may find in the "rootCA" directory the root CA to sign your request with. Use "opensipsctl tls userCERT" command to create a new certificate; the rootCA password is "opensips". What is the purpose of these default CA and certificate? First to make an out-of-the box TLS configuration for users not so familiar with SSL/TLS. Second, to give access to the same CA root to a large community in order to encourage testings and interconnections via TLS with minimum of troubles.
