As a PRTG user, I want to manage SNMP devices with the latest and most secure SNMP encryption parameters. In addition many device manufactorer use SHA-256 as default and it is very annoying to configur them back to an older and less reliable standard.
Details of user story
SNMPv3 uses for authentication MD5, SHA-1 or SHA-2(256/384/512). the later should be supported. According to BSI only SHA-2 and SHA-3 can are safe! https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Publikationen/TechnischeRichtlinien/TR02102/BSI-TR-02102.pdf?__blob=publicationFile page 46/47.
SNMP-Credentials for authentication offer the option MD5, SHA, SHA256, SHA384, SHA512 Optional also enable encryption with AES256 This basically gives us a set of cornerstones that need to be there in order for the feature to be implemented.
