Need a Python library for generating WSSE headers for API calls

Our API requires WSSE headers to communicate with the server. We presently have generators written in Java, PHP, C# and JavaScript. All produce the same output. We now want to add Python to the list.

What we want out of this project:

1- A code library that customers can integrate into their own projects

2- Unit tests to confirm the code is working as expected

3- Documentation explaining how the code works

The following information is needed to generate a WSSE header:

1- The name of the customer as it appears in the software;

2- A nonce, which is a random string generated by you. This string must be different with each request;

The current date & time in UTC-0. See [login to view URL] for more information;

3- Username – Your username;

4- API token – A unique token assigned to you by us.

The following PHP script demonstrates how to generate a WSSE header. This code can be easily tested using PhpFiddle ([login to view URL]).




$username = "YOUR_USERNAME";

$token = "YOUR_TOKEN";

$key = md5($username);

$cryptAlgo = 'AES-256-CFB';

$iv = mb_substr(base64_decode($token), 0, 16, '8bit');

$secret = base64_encode($iv.openssl_encrypt($token, $cryptAlgo, $key, 0, $iv));


$current_time = date('c');

$nonce = md5(rand(), true);

$base64_nonce = base64_encode($nonce);

$password_digest = base64_encode(sha1($nonce . $current_time . $secret, true));

$header = "UsernameToken Username=\"$username\",".





echo $header;



The following Javascript script demonstrates how to generate a WSSE header. This code can be easily tested using Postman ([login to view URL]).


var moment = require('moment');

var username = "YOUR_USERNAME",


token = "YOUR_TOKEN",

key = [login to view URL](username).toString(),

iv = atob(token).substring(0, 16).toString([login to view URL]),







utf8iv = [login to view URL](iv),

utf8key = [login to view URL](key),

utf8token = [login to view URL](token);

encrypted = [login to view URL](utf8token, utf8key, {

iv: utf8iv,

mode: [login to view URL],

padding: [login to view URL]


secret = btoa(iv + encrypted);

created = moment().utc().format();

created = [login to view URL](0, [login to view URL] - 1) + '+00:00';

nonce = [login to view URL]() * 32767 + '0';

nonce = [login to view URL](nonce).toString();

var stringToSha1 = nonce + created + secret;

var sha1Temp = [login to view URL](stringToSha1, {

asBytes: true


base64Nonce = btoa(nonce);

passwordDigest = [login to view URL](sha1Temp);

header = `UsernameToken Username="${username}",PasswordDigest="${passwordDigest}", Nonce="${base64Nonce}", Created="${created}", Organization="${orgName}"`;
