Polynomial-C commented 8 years ago

Please also note that openssl-1.1 can be compiled with three different compatibility levels:

--api=0.9.8, --api=1.0.0 and --api=1.1.0.

The important information here is that with --api=1.1.0 all interfaces seen as deprecated by openssl developers won't be available anymore. So please carefully check your code for usage of deprecated interfaces.
