Hi.

I encountered problem with SNMPv3 when I launched latest VMware Zabbix appliance solution (6.4.11) to test some data exchange. I can't decipher SNMP request when hash native key length is shorter than cipher key length, for example, MD5 with AES-256 (leaving aside considerations about security - this is the correct combination that the system allows you to set, and the user who sets these parameters expects that my device will return the correct answer to him). It is clear that Zabbix use different key expansion algorithm than described in CISCO draft so Wireshark can't correctly unencrypt message. I wrote a simple program on Java to test decipher algorithm with accordance with CISO draft and got same results as Wireshark. Please provide me with appropriate algorithm itself used in Zabbix or link to its documentation.
