you don't know what entrypy is, right?
on linux do:

# cat /proc/sys/kernel/random/entropy_avail
3940

if this number gets to 0, you'll have problem with using /dev/random (which
is a blocking device) that leeds to problems like you have described.

using /dev/urandom instead should help.
there are daemons like haveged that can help you provide entropy.

some HW random number generators provide entropy source.
