If you're doing it in js, then lift gibson's code here
https://www.grc.com/r&d/js.htm
or use the stanford js library built by Dan Boneh et all
http://bitwiseshiftleft.github.io/sjcl/doc/symbols/sjcl.random.html
.
Make sure you send the js over an ssl connect to avoid a MITM code substitution. You can also sign the code with the websites cert. JS crypto is hard.

RdRand (also RDRAND) is an instruction for returning random numbers from an on-chip random number generator.RdRand is available in Ivy Bridge processors and is part of the Intel 64 and IA-32 instruction set architectures. The random number generator is compliant with security and cryptographic standards such as NIST SP800-90, FIPS 140-2, and ANSI X9.82.
