Hi,
Hi, thanks for reply,

Here you have a list of random number generators that are available on the
market:

Nice list, i have been trying to use /dev/urandom, even have compiled
gnupg with changes in configure file where i have changed all
/dev/random /dev/srandom to /dev/urandom, but that doesn't help at
all...


/dev/urandom is bad for your security


Not always.

Here is a portion of the man page from OS X:

/dev/urandom is a compatibility nod to Linux. On Linux, /dev/ urandom will
     produce lower quality output if the entropy pool drains, while
/dev/random will prefer to block and wait for additional entropy to be collected. With Yarrow, this choice and distinction is not necessary,
     and the two devices behave identically. You may use either.


That said, it makes sense to know the system you're building on.
