Hash_hmac sha512 authentication in python
I am trying to write python authentication bot for: https://comkort.com/page/private_api
There is no complete php example. I am guessing someone might put it here.
There is only php code snippet:
$query_string = http_build_query($_POST, '', '&');
$ethalon_sign = hash_hmac("sha512", $query_string, $api_secret_key);
How to write authentication in python with hash_hmac sha512?
I want to remove mine open orders
POST https://api.comkort.com/v1/private/order/list
.
My current option:
import hashlib
import hmac
import requests
import time
privateKey = b'myprivatekey'
publicKey = 'my public key'
url = 'https://api.comkort.com/v1/private/order/list'
tosign = b'market_alias=doge_ltc'
signing = hmac.new( privateKey , tosign, hashlib.sha512 )
headers = {'sign': signing.digest(), "apikey": publicKey, "nonce": int( time.time() ) }
r = requests.get(url, headers=headers)
print r.text
I caught it
{"code":401,"error":"Invalid sign","field":"sign"}
Maybe hexdigest () instead of digest ()? I don't know, I am playing around with this prefix b
and the different hmac outputs, every time I catch one error: "Invalid character".

If anyone is interesting, I solved it myself.
#!/usr/bin/python
import hashlib
import hmac
import requests
import time
apikey = '';
apisecret = '';
def request_comkort( url, payload ):
tosign = "&".join( [i + '=' + payload[i] for i in payload] )
sign = hmac.new( apisecret, tosign , hashlib.sha512);
headers = {'sign': sign.hexdigest(), 'nonce': int( time.time() ), 'apikey': apikey }
r = requests.post(url, data=payload, headers=headers)
return r.text
# Get balance
print request_comkort( "https://api.comkort.com/v1/private/user/balance";, {} )
# Get Open Orders
print request_comkort( "https://api.comkort.com/v1/private/order/list";, {'market_alias': "DOGE_LTC" } )
# Make Ask
print request_comkort( "https://api.comkort.com/v1/private/order/sell";, { 'market_alias':"HTML_DOGE", "amount": "1000", "price": "123123" } )
# Cancel order
print request_comkort( "https://api.comkort.com/v1/private/order/cancel";, { 'order_id': 10943 } )
