[syslog-ng]Encryption?

Hello: I've started looking into using syslog-ng and it looks very nice. I was curious about the encryption option in the sample config. How is that accomplished? Where would the documentation for that option be? How comparible is syslog-ng to syslog in performance terms? Obviously encryption would increase the load and that is acceptable to a point. Thanks for your assistance. Brian Seppanen Charter Communications Regional Data Center 906-228-3100 ext 23 Marquette, MI seppy@chartermi.net
