Re: Does Net-SNMP support AES192 or AES256?

Simon,

The USM AES192 and AES256 support is based upon an Internet Draft, which
never became a standard - therefore, you have to pass
"--enable-blumenthal-aes" to ./configure. (You don't have to enable TSM or
the TLS transports; that's a whole different kettle of fish.)
