# Pseudo Random Number Generator (PRNG): # Configure one or more sources to seed the PRNG of the SSL library. # The seed data should be of good random quality. # WARNING! On some platforms /dev/random blocks if not enough entropy # is available. This means you then cannot use the /dev/random device # because it would lead to very long connection times (as long as # it requires to make more entropy available). But usually those # platforms additionally provide a /dev/urandom device which doesn't # block. So, if available, use this one instead.
