    Why not just put it on Github?

    Sorry for the delay, but I forgot to subscribe to notifications for this thread.

    I purchased it via Amazon on May 22, 2018 at this link:

    What is the contact information for support?

    in reply to: Library and pgm #2237

    That did it, thank you!

    I’m having problems with the OpenSSL engine.

    * openssl rand -engine truerng -hex 16
    * demo_openssl

    work as expected, but when i try

    * openssl engine -c -t -vvvv truerng

    I get:

    139865069244800:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:187:filename(/usr/lib64/engines/ /usr/lib64/engines/ cannot open shared object file: No such file or directory

    139865069244800:error:2606A074:engine routines:ENGINE_by_id:no such engine:eng_list.c:391:id=truerng

    A note that is in /usr/local/lib, not /usr/lib64/engines.

    I tried copying and pasting the contents of truerng.cnf into /etc/ssl/openssl.cnf, but it didn’t make a difference.

    in reply to: TrueRNG Pro Voltage? #2182

    Bump? Are the mods here?

    I sometimes get 85xx-86xx depending on the USB port it’s plugged into. But never anything above that. Can anyone please tell me why the voltage is lower than the official numbers 8800-9800, and the effects of it if any?

    in reply to: Feeding Windows entropy pool #2146

    According to these three links:

    …it was once possible for developers to incorporate additional sources of entropy, but this was discontinued in Windows 8 and later, in favor of a TPM.

    There are, however, sources of entropy in addition to a TPM (or when a TPM is unavailable). Microsoft is vague as to how these sources are used or to what extent each source is taken into account. It would appear that this is per-application rather than a single /dev/random

    Reading those articles, it would seem that a Windows equivalent of rngd, using TrueRNG hardware, could affect entropy per-application in the following ways:

    * Incrementing the serial port count by 1
    * Occasionally writing random amounts of TrueRNG-generated random bytes to memory (and/or the page file), using a random amount of threads
    * Adding one or more TrueRNG-generated nonsense environment variables to the system that occasionally change
    * The fact that a program exists doing all this

    Something like this would be interesting. Unfortunately it would be tough to prove how/if it has any effect.

    To create a B&W image of the same size:

    rawtopgm 512 512 < /dev/random | pnmtopng > random.png

    in reply to: Library and pgm #2144

    Since I bought the Pro model I’ve been editing my favorite old Roguelikes to use /dev/random via getrandom() as that will allow me to use something else instead of/together with /dev/TrueRNG. However, the Web instructions to change the mode of TrueRNG Pro don’t seem to work at all for me, while your program does. Thank you!
