+ Note on random number generation
+ --------------------------------
+
+ Availability of cryptographically secure random numbers is required for
+ secret key generation. OpenSSL provides several options to seed the
+ internal PRNG. If not properly seeded, the internal PRNG will refuse
+ to deliver random bytes and a "PRNG not seeded error" will occur.
+ On systems without /dev/urandom (or similar) device, it may be necessary
+ to install additional support software to obtain random seed.
+ Please check out the manual pages for RAND_add(), RAND_bytes(), RAND_egd(),
+ and the FAQ for more information.
