Here, I choose a user profile to configure for access (username).
In this case, I have created 2 users, both which use SHA1 (instead of MD5 or none) for auth, but one uses DES for encryption while the other uses AES for encryption and each have different usernames:
Here is what a user configuration screen would look like:
You would want to specify your own username and a more random "Authentication Passphrase" and "Privacy Pasphrase" : In this case, these settings are for the user account that uses AES. You can create an account that uses AES if you want to, but...
FOR FIRST TESTS, CHOOSE "DES" NOT AES.
(I've seen problems with nut talking AES from OPNSense, even through all other things being equal, DES works fine.)
Next, Visit Configuration -> Network -> SNMPv3 -> Access Control
It is possible and likely that the Network Management Card I am testing supports a strange variation of AES whcih snmpwalk and others support, but "nut" does not.
Another note for this UPS Network Management Card:
* User Password form is limited to 32 characters.
* Encryption password is limited to 32 characters.
