I don't want to sound stupid but there's one thing that i need answer for
So a bitcoin private key is actually a random integer between 1 and 2^256 right and bitcoin wallet generate it randomly by using PRNG.
Ok so what's stopping PRNG from choosing say a random integer between 1 and 100000? Won't that make your private key insecure?
There's this website https://privatekeys.pw/keys/bitcoin/1
Here you can actually easily search private keys for any random integer value. So say if PRNG gives private key for value 9000000 then it's insecure right?
How to make sure the private key generated by bitcoin wallet is high quality?
