polarbear's Issues

Polarbear produces signature result which is different from "cetcli tx sign"

OS: Ubuntu 16.04.
Two issues:

Polarbear produces signature result which is different from "cetcli tx sign"
Polarbear produces different signature results with the same input.

The following python3 code can reproduce the issues on Ubuntu 16.04.

secret = 'xxxxxxxxx'
chain_id = 'coinexdex2'

# init wallet
import ctypes
from pathlib import Path
home = str(Path.home())
path = '{}/.cetcli/keys'.format(home)
lib = ctypes.CDLL('/home/ubuntu/exchanges-res/coinexdex/polarbear/sdkforpython/wallet_linux.so')
# lib = ctypes.CDLL('/home/ubuntu/exchanges-res/coinexdex/polarbear/wallet.so')
lib.BearInit(path.encode('utf-8'))
key_name = '0a542970-9fc7-11ea-a52f-00163e024c1c'

# get account_number and sequence
account_number = '339981'
sequence = '3' 

# sign and broadcast
sign = lib.SignAndBuildBroadcast
sign.restype = ctypes.c_char_p

unsigned_tx_bytes = '{"type":"cosmos-sdk/StdTx","value":{"msg":[{"type":"bankx/MsgSend","value":{"from_address":"coinexxxxxxxxxxxxx","to_address":"coinexyyyyyy","amount":[{"denom":"cet","amount":"100000000"}],"unlock_time":"0"}}],"fee":{"amount":[{"denom":"cet","amount":"4000000"}],"gas":"200000"},"signatures":null,"memo":""}}'.encode('utf-8')
print('to_sign', unsigned_tx_bytes)
bz = sign(key_name.encode('utf-8'), secret.encode('utf-8'), unsigned_tx_bytes, chain_id.encode('utf-8'),
          'block'.encode('utf-8'), int(account_number), int(sequence))
print('signed', bz)
