What is is minimum possible number for an ECDSA private key? 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.
