Oh my, if you are right with your first guess, this is a bad DRNG design. Just out of curiousity: what happens if a caller invokes the seed function twice or more times (each time with the sufficient amount of bits)? What is your guess here?
Should the second seed use the random data generated by the device? Regards, PrasannaKumar
