I'm trying to connect to an API and they only provide guides for python & Javascript. I'm trying to find the equivalent for php but coming up short.
For additional reference: https://docs.deribit.com/#authentication
I'm unable to get the proper signature in PHP.
Javascript:
var timestamp = Date.now();
var nonce = "abcd";
var data = "";
var signature = CryptoJS.HmacSHA256(`${timestamp}\n${nonce}\n${data}`, accessSecret).toString();
Python:
timestamp = round(datetime.now().timestamp() * 1000)
nonce = "abcd"
data = ""
signature = hmac.new(
bytes(clientSecret, "latin-1"),
msg=bytes('{}\n{}\n{}'.format(timestamp, nonce, data), "latin-1"),
digestmod=hashlib.sha256
).hexdigest().lower()
PHP: (*I don't know how to create the nonce)
$timestamp = number_format(microtime(true) * 1000, 0, '.', '');
$nonce = number_format(microtime(true) * 1000, 0, '.', '');
$data = "";
$key = $timestamp.$nonce.$data;
$sign = hash_hmac('sha256',$key,$secret);
$sign = bin2hex($sign);
For the random generation required 'a-z0-9', 8 characters
you may please use chr and rand to do the job.
Hence try the following
<?php
$x1= chr(rand(0,25)+97) ;
$x2= chr(rand(0,9)+48) ;
$x3= chr(rand(0,25)+97) ;
$x4= chr(rand(0,9)+48) ;
$x5= chr(rand(0,25)+97) ;
$x6= chr(rand(0,9)+48) ;
$x7= chr(rand(0,25)+97) ;
$x8= chr(rand(0,9)+48) ;
$nonce = $x1.$x2.$x3.$x4.$x5.$x6.$x7.$x8;
?>
