I already test the usb random number generator Araneus Alea I with OSX (unix bsd).

After compiling the i found errors as below:

root:/Users/amir/linux$ make
cc randomfile.c -lusb -o randomfile
randomfile.c:16:17: error: usb.h: No such file or directory
randomfile.c: In function 'main':
randomfile.c:74: error: 'usb_busses' undeclared (first use in this function)
randomfile.c:74: error: (Each undeclared identifier is reported only once
randomfile.c:74: error: for each function it appears in.)
randomfile.c:74: error: dereferencing pointer to incomplete type
randomfile.c:75: error: dereferencing pointer to incomplete type
randomfile.c:75: error: dereferencing pointer to incomplete type
randomfile.c:76: error: dereferencing pointer to incomplete type
randomfile.c:77: error: dereferencing pointer to incomplete type
randomfile.c:84: warning: assignment makes pointer from integer without a cast
make: *** [randomfile] Error 1

I need to configure libusb to generate usb.h and other related header files.

I edit the Makefile and alter the parameter as below:
randomfile: randomfile.c
cc -I/opt/local/include -L/opt/local/lib \
randomfile.c -lusb -o randomfile

After that make it again:

cc -I/opt/local/include -L/opt/local/lib \
randomfile.c -lusb -o randomfile
randomfile.c: In function 'main':
randomfile.c:99: warning: pointer targets in passing argument 3 of 'usb_bulk_read' differ in signedness

Phew, ignore the error. Basically its no error, but warning. After successcully compile the .c file, one binary file generated called randomfile

Let test the tools:

./randomfile 1000 > random.hex

one file generated random.hex with these:

The simplest way to integrate the Alea I with dnssec-keygen is to use the "randomfile" program which is provided as C source on the Alea I driver CD, and pipe its output into the standard input of the dnssec-keygen program. For example, this command will generate a 2048-bit RSA zone key for the "my" TLD:

sudo randomfile -b | dnssec-keygen -r /dev/fd/0 -a RSASHA1 -b 2048 my.

Here, the "-b" causes the randomfile program to output the randomness in binary form (which is what dnssec-keygen expects), and the "-r /dev/fd/0" causes dnssec-keygen to read randomness from standard input instead of /dev/random. Note that the randomfile program needs to be run as root unless you set up specific udev rules to give non-root users permission to access the Alea I USB device.

After a while:

Next week(24 April 2009 until 1 May 2009) I will be in Sabah & Sarawak. I will represent MyNIC BHD. as presenter to talk about Domain Name System Security Extention (DNSSEC). The audiences will be government and educational institution. See you all there. For more info please visit http://rnd.domainregistry.my
