They are very different. On my amd64 machine, libcrypto.so.0.9.8 is definitely in /usr/lib, and that's not just the optimized version (since such a version doesn't exist for amd64). The code it uses from libcrypto is only MD5. There are several interface-compatible versions out there if it's decided that ping6 shouldn't link to libcrypto.
