I assume you're getting a failure. If so, it is because you did
not load the default provider in addition to the legacy one.
Otherwise your code is OK, although these days the RAND_seed() call
should not be needed at all, the RNG should be seeded by itself unless
there is something wrong with your build configuration of the OpenSSL
or your OS is some awkward legacy one.
