Title: Why do private keys have a range limit?
Post by: Bitcoin on Feb 20, 2022, 04:43 am
Why do private keys have a range limit?

I am reading about ECDSA, and I find that the private key must be in (0,n), with n = FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364141.


Is n the total number of points on the secp256k1 curve? (plus the 0 point)


And how does n limit the range of private keys?


What if a private key is bigger than n?
