----------------------------------------

             Summary: ast_tls_cert: don't re-create generated files
                 Key: ASTERISK-21932
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21932
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Contrib/General
    Affects Versions: 11.4.0
            Reporter: Tzafrir Cohen
            Severity: Minor


ast_tls_cert is a script that creates a simple CA (certification authority), which is handy when experimenting with TLS.

If you run:

ast_tls_cert # generate default certificate
ast_tls_cert -C some-host -o some-host

the first run will generate cat.cfg, ca.crt and ca.key , but the second run will run over them, which is counter-intuitive.

This patch makes the script use the existing CA files if they already exist.
