No. There's an entire field dedicated to trying to identify patterns like these. Much easier to dissemble your OTP and find the code. I did do a quick check to see if it was a Linear Congruence Generator, and was going to post the results, but all of the tools I wanted to use to test with were in matlab. I don't have matlab and it didn't make sense for me to rewrite the tools. If you wanted to dig further, look at LRCs and bitwise arithmetic. Those are the two most likely "lazy" choices for a cheap hash function. | |
