Perl5 module to get random data from online sources
NetRandom - get random data from online sources
This module gets truly random data from online sources. Or at least, they claim to be truly random.
The two sources of randomness above correspond to http//www.fourmilab.ch/cgi-bin/uncgi/Hotbits?nbytes=1024&fmt=hex and http//random.org/cgi-bin/randbyte?nbytes=1024&format=hex. We always get chunks of 1024 bytes at a time, storing it in a pool which is used up as and when needed. The pool is shared between all objects using the same randomness source. When we run out of randomness we go back to the source for more juicy random goodness.
The maintainers of both randomness sources claim that their data is truly random. A some simple tests show that they are certainly more random than the rand function on this ‘ere machine.
