After suffering through yet another fun day of setting up TLS certs for asterisk, I figured I'd knock out a quick script so I don't ever have to do it again.


  /branches/1.8/contrib/scripts/ast_tls_cert PRE-CREATION 

Diff: https://reviewboard.asterisk.org/r/979/diff


I've generated a CA, client, and server cert, installed the client and CA certs on the Blink softphone, and set the server and CA certs in sip.conf. Everything works.

./ast_tls_cert -C pbx.mycompany.com -O "My Company"
./ast_tls_cert -m client -C "Joe User" -O "My Company" -c ca.crt -k ca.key -o joe_user

The first run would create the CA certs since the -c option wasn't passed and also asterisk.pem which would be copied to /etc/asterisk (or wherever) and used as the tlscertfile in sip.conf. The ca.crt can also be copied over and used as the tlscafile.

The second run would create a client certificate using the previously created CA cert and write out joe_user.pem. I then copied ca.rt and joe_user.pem and configured Blink to use them and to verify the server.
