generate_Ku errors

[M.Daulat R. <da...@es...>]

Hello, 

I don't know if this belongs in the users list or the coders, since the
problem I am
having is with "coding" I am sending to the coders list..

I generated the net-snmp windows binaries with SDK and OpenSSL enabled.

I can run the following command from windows command prompt successfully.

====
snmpget -v 3 -u MD5User -a MD5 -A "The Net-SNMP Demo Password"  -l
authNoPriv  test.net-snmp.org  system.sysUpTime.0
====

When I try to replicate the above programmatically using MS VC++, I get an
"Error generating Ku from authentication
pass phrase".

I have done google searches and read various posting but I just can't seem
to get a handle on
this problem.

Here is the relevant code snippet:
===
 const char *our_v3_passphrase = "The Net-SNMP Demo Password";
 session.securityAuthProto = usmHMACMD5AuthProtocol;
 session.securityAuthProtoLen = sizeof(usmHMACMD5AuthProtocol)/sizeof(oid);
 session.securityAuthKeyLen = USM_AUTH_KU_LEN;

 if (generate_Ku(session.securityAuthProto,
                    session.securityAuthProtoLen,
                    (u_char *) our_v3_passphrase, strlen(our_v3_passphrase),
                    session.securityAuthKey,
                    &session.securityAuthKeyLen) != SNMPERR_SUCCESS) {
..

Please help!! I am willing to read and learn but I need some mentoring!!

Thanks!
