 Description   

Steps to reproduce:

  1. Install Zabbix Server on Red Hat 9 from sources (packages are not provided)
  2. try to use DES for SNMPv3 Privacy protocol or SHA-1 for Authentication protocol

Result:
Not supported items

Expected:
DES not usable at all, SHA-1 can be enabled, but not recommended.

Should be documented:

Just a note. In such case host SNMP interface shows an error:

Unsupported privacy protocol [0]

Which is a result of compilation, I think, defined here https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/src/zabbix_server/poller/checks_snmp.c#656

That's actual for official zabbix packages too.

And when you test it from command line, error is:

Invalid privacy protocol specified after -3x flag: DES
