Hi all,

I have just finished a batch of work upgrading net-snmp to support certificates from CAs using intermediate certificates like Let’s Encrypt. All the patches have been accepted and will appear in future release of net-snmp v5.10+.

As part of that work I have added the required support to collectd-snmp to support DTLS/TLS with SNMP. This involved teaching collectd how  to pass the correct additional parameters.

Two PRs have been submitted:

https://github.com/collectd/collectd/pull/3803 - support DTLS parameters.
https://github.com/collectd/collectd/pull/3805 - support for SHA224/SHA256/SHA384/SHA512

The PRs include updates to the documentation to be clear as what you need to do and what you should not do to make SNMPv3+DTLS work.

Would it be possible for someone to take a look when they get a chance?
