[SNMP4J] SNMP4J 2.4.0-SNAPSHOT provides SHA-2 support as defined by RFC 7630

[Frank Fock]

Hi,

The latest SNMP4J 2.4.0 SNAPSHOT implements the SHA-2 authentication
protocols defined by the upcoming RFC 7630
(see https://www.rfc-editor.org/auth48/rfc7630 ).

Until now I could not find any other open source implementation for 
interoperability
tests. If you are aware of such an implementation, please contact me by 
email.

Best regards,
Frank
