comment Why is “mod(n)” so central to most aspects of cryptography?
Here is the official take on duplicate questions on this site Where this particular question falls I'm open to whatever is decided.

Part 2 - Could this "risk" be explained to management as the quantity of brute force attempts that we will tolerate? (substitute brute force for X chosen message attacks etc) and 2^64 is the minimum required due diligence?

Part 1 - Could this number (1/2^32) be compared to a Birthday Attack, where the distribution is non-uniform? Namely, where there there is tipping point of where 0.. to some negligible number increases rapidly to a non-negligible number?

@curious Yes, they are from his coursera course. It's really good and packed full of information. I discovered this 2 weeks ago and am trying to finish all the classes in 1 month so I can start the next one on time.

I'd be curious to see your C# implementation. Do share a link if you can.

Is it correct for me to think/say "negligible in terms of brute forcing". Does negligible apply to any other attack other than brute forcing?
