Need to double (or) half the range of private key , so how to convert the bitcoin public key into doubled (or) half private key range
n = 1 to ( FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140 * 2 ) OR
n = 1 to ( FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140 / 2 )
Thank all
Seems to me you could halve the range by performing the bitwise OR operation on your private key, forcing it to be an odd number.
But you can't use Secp256k1 and double the range becuase for any value above FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140 you'd be cycling over the same public keys.
