user54748: Private keys are 256 bit numbers. I know the max. possible number is something around:

What about the min. number possible?
Thanks. 

user52021: One is the minimum number. [This space intentionally left unblank.]

user5406: 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.
