ozzi- / tlscheck.sh
Created Oct 30, 2020
check supported tls versions of a server by defining a minimum allowed version
View tlscheck.sh
#!/bin/bash
# tlscheck will check if a specified url supports the defined mimum tls version and higher
# this is helpful to ensure hardening (i.E. does my server support 1.2 and newer only?)
# exit codes above 9 will signalize the tls version check that failed (i.E. 11 = TLS 1.1)
# exit codes below 6 will signalize wrong syntax
# exit code 6 means could not connect at all
