Private keys are 256 bit numbers. I know the max. possible number is something around: 115792089237316195423570985008687907852837564279074904382605163141518161494336
What about the min. number possible?
Thanks.

The all-zero bitstring doesn't have a corresponding public key per the standard (according to "Are all possible EC private keys valid?" on Crypto.SE), so it's 000…001.

One is the minimum number. [This space intentionally left unblank.]

If only I'd thought of that to get around the minimum answer length. :) – G. Maxwell Sep 22 '18 at 02:18
