Question

Problem
Many functions in the OpenSSL library require the use of the OpenSSL pseudo-random number generator. Even if you use something like /dev/urandom yourself,
OpenSSL will use its own API under the hood and thus must be seeded properly.
Unfortunately, some platforms and some older versions of OpenSSL require the user
to provide a secure seed. Even modern implementations of OpenSSL merely read a
seed from /dev/urandom when it is available; a paranoid user may wish to do better.
When using OpenSSL, you may want to use the provided PRNG for other needs, just
for the sake of consistency.
