It's not even close to 128.
The closest I've come up with 8 to 2 ** 65
30568377238562584866, b'\xc9\xd9\x1d\xbc\x16\x9d\xdb\x86'
Code:
import random
puzzle = 65
lower_range_limit = 2 ** (puzzle - 1)
upper_range_limit = (2 ** puzzle) - 1
owner_salt = b'\xc9\xd9\x1d\xbc\x16\x9d\xdb\x86'
random.seed(owner_salt)
dec = random.randint(lower_range_limit, upper_range_limit)
print(f"{dec}, {owner_salt}")
puzzle = 65
lower_range_limit = 2 ** (puzzle - 1)
upper_range_limit = (2 ** puzzle) - 1
owner_salt = b'\xc9\xd9\x1d\xbc\x16\x9d\xdb\x86'
random.seed(owner_salt)
dec = random.randint(lower_range_limit, upper_range_limit)
print(f"{dec}, {owner_salt}")
but even so a part is missing to get a 100% accurate result.
it seems most likely that pbkdf2_hmac was used
hashlib.pbkdf2_hmac('sha512', os.urandom(8 ), b'', iterations=1024)[:32]
some combination like this.
from_arbitrary_size_secret()
Code:
def normalize_secret_bytes(cls, privkey_bytes: bytes) -> bytes:
scalar = string_to_number(privkey_bytes) % CURVE_ORDER
if scalar == 0:
raise Exception('invalid EC private key scalar: zero')
privkey_32bytes = number_to_string(scalar, CURVE_ORDER)
return privkey_32bytes
scalar = string_to_number(privkey_bytes) % CURVE_ORDER
if scalar == 0:
raise Exception('invalid EC private key scalar: zero')
privkey_32bytes = number_to_string(scalar, CURVE_ORDER)
return privkey_32bytes
As the creator said, you need to trim the high bytes of the key with zeros!
