Other possible options:

http://www.seeedstudio.com/depot/FST01-with-Heat-Shrink-Tube-p-1277.html?cPath=6_12

And even more options (some in development):

Thanks, I bought that one off ubld.it. Id like to support the NZ guys, but they don't seem ready to ship.

entropykey shipped complete with simple open drivers which fed the entropy into the kernel's /dev/(u)random pool thus augmenting rather than replacing everything else your system could draw on. You don't really need it unless you are running headless VM servers with no moving parts or user interaction.

They have been out of stock for months and months.
I emailed them for a date, but they never replied.

bitcoin uses openssl's RAND_bytes to generate its keys. According to https://www.openssl.org/support/faq.html, it does use /dev/random to obtain entropy.

Thanks, for < $50 will be buying one.

what is entropy in random number generation???

Cool

I have been looking at USB Random Number Generators. If I install one on a Unbuntu system, then I assume the kernel and then Bitcoin Core will use this as its entropy?
