Hi Daniel,

Thank you for reporting this. Nping requires SHA-256 for its "Echo Mode"
protocol but, as you may know, it is possible to disable cryptographic
support using:

./configure --with-openssl=no

Unfortunately there is no way to have crypto support without SHA-256, so
users with OpenSSL<=0.97 will have to upgrade (0.9.8 has been around for
almost 6 years so I expect systems with 0.9.7 or less to be a tiny

You'd be surprised. There's still a lot of OS X 10.5 users around as that's the last version that supports ppc and 
there are still a LOT of ppc Mac users.

Anyway, I've added a check for EVP_sha256() that aborts compilation in
case of failure. I attach a new version of configure.ac. Could you
please give a try and let me know if it works?

Thank you and best regards,

Luis MartinGarcia.

This looks fine, but as I only have OS X 10.6, which has openssl 0.9.8, I can't test.
