Yo @nomachine, what's that error dev/urandom thingy?
There is no problem with urandom it is enough random for all cryptographic purposes.
Please all read the next article:
https://www.2uo.de/myths-about-urandom/@nomachine one of the Hardware device that it is include most modern Intel processors, that is used to feed the entropy of the CSRNG of the linux kernel and windows core, use Thermodinamic properties to generate True random data:
From:
https://www.intel.com/content/www/us/en/developer/articles/guide/intel-digital-random-number-generator-drng-software-implementation-guide.htmlThe ES runs asynchronously on a self-timed circuit and uses thermal noise within the silicon to output a random stream of bits at the rate of 3 GHz. The ES needs no dedicated external power supply to run, instead using the same power supply as other core logic. The ES is designed to function properly over a wide range of operating conditions, exceeding the normal operating range of the processor.
So that means that most of the modern PC are cable to generate True Random data.
