You must use @strong{cryptographically good} pseudo random number
generator. By default we use default @code{crypto/rand} library that
-reads @code{/dev/urandom} source. Some GNU/Linux and FreeBSD systems
+reads @file{/dev/urandom} source. Some GNU/Linux and FreeBSD systems
are rather good with this entropy source. Closed proprietary ones are
always not and you must use optional @ref{EGD} feature with them.
