Net-SNMP docu: Authentication protocols support

Net-SNMP 5.8 and later supports all the authentication protocols defined in RFC7860
  • SHA-192
  • SHA-256
  • SHA-284
  • SHA-512
Starting with release 5.8 AES192 and AES256 are an optional configuration option, it must be enabled during package build. To check used options run this: 
net-snmp-config --configure-options # check directive --enable-blumenthal-aes
This however works only for cmd line utilities like snmpwalk, Perl module has that supported since 5.9.1 (May 26, 2021).
This is available in the latest distribution versions (RedHat 9, Debian 12 and newer).

DES

Latest RedHat distros (RHEL9+) do not have DES enabled, you can check it via: 
net-snmp-config --configure-options # check directive --disable-des

RedHat 8

Use this package net-snmp-perl-5.8-30.el8.x86_64.rpm to support these protocols:
  • Authentication protocol: MD5|SHA|SHA-224|SHA-256|SHA-384|SHA-512
  • Privacy protocol: DES|AES|AES-192|AES-256
dnf reinstall net-snmp-perl-5.8-30.el8.x86_64.rpm

Debian 11

Use below packages to support these protocols:
  • Authentication protocol: MD5|SHA|SHA-224|SHA-256|SHA-384|SHA-512
  • Privacy protocol: DES|AES|AES-192|AES-256
