Example: 'hardened-mode' = secure

Possible values: relaxed|secure|strict

Description: Adjusting hardened mode affects handling of security aspects within Tigase. The higher the level the more strict are the rules: * relaxed - uses default security capabilities from installed JVM; * secure - disables old SSLv2 and SSLv3, disables weak cyphers; * strict - in addition to secure level changes it also disables TLSv1 and TLSv1.1 as well as ciphers that don’t support Forward secrecy.

On older JVM versions it required UnlimitedJCEPolicyJDK installed. It’s not required with OpenJDK8 and newer an OracleJVM 11 and newer.
