Hello,

SNMPv3 provides integrity, authentication, and encryption of the message (which is the community)

The explanation of the options are:

Noauth,Nopriv= No authentication and no privilege which means:  authentication without encryption.

Use a username match for authentication

authNopriv= Authentication and No privilage wich means: Authentication + Hashing but still without encryption

provides authentication based on the Hash-Based Message Authentication Code (HMAC) Message Digest 5 (MD5) algorithm or the HMAC Secure Hash Algorithm (SHA)

authpriv= Authentication and Privilege: which means Authentication + Hashing + encryption and this option which make SNMPv3 secure

The same of authnopriv adding to it DES encryption.
