[ndnSIM] Using openssl with ndnSIM

Sun Feb 15 16:14:15 PST 2015

Hi Cesar,

Yes. There is no longer openssl branch or the need for such branch.  In the new version, you can make full use of CryptoPP library.  Also, many of the security-related tasks can be done using ndn-cxx library directly, which also uses cryptopp library internally.

I can’t see this branch in the latest ndnSIM version and I’m wondering if the feature was merged with the master branch. I didn’t try to use openssl libraries with ndnSIM yet, I just wanted to make sure that I can compile if I do.

When I build, I am still getting (undefined reference to `SHA1') which means that the crypto lib is not being linked. I also can't see it in the compile command:
