- * Implements the ssh.softwareversion keyword
- * You can match over the software version string of ssh, and it will
- * be compared from the beginning of the string so you can say for
- * example ssh.softwareversion:"PuTTY" and it can match, or you can
- * also specify the version, something like
- * ssh.softwareversion:"PuTTY-Release-0.55"
- * I find this useful to match over a known vulnerable server/client
- * software version incombination to other checks, so you can know
- * that the risk is higher
