How to send soap request with SHA2 and TLS version 1.2 - php

I just wanted to send Soap request to the soap server using SHA2 and TLS1.2 but it's showing below error when trying to create soap client
Error
SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://example.com/wsdl' : failed to load external entity "https://example.com/wsdl"
Code
$url = 'https://example.com/wsdl';
$client = new SoapClient(
$url,
array(
'ssl_method' => SOAP_SSL_METHOD_TLS,
'cache_wsdl' => WSDL_CACHE_NONE,
'stream_context'=> stream_context_create(
array(
'ssl'=> array(
'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
'ciphers' => 'SHA2',
'verify_peer'=>false,
'verify_peer_name'=>false,
'allow_self_signed' => true //can fiddle with this one.
)
)
)
)
);

Have solved by adding SHA256 in ciphars. Actually SHA2 has 4 kinds of hash functions: SHA224, SHA256, SHA384 and SHA512.
Changes
'ciphers' => 'SHA256',
Answering own question is little odd for me but it can help other devs.

Don't you have a certificate to place in the ssl array?
'cafile' => $certFile

problem accessing soap web service's production environment

I hope this question won't be marked as duplicate as I read many related questions and answers on the site: although I tried most of the suggestions out there I still couldn't resolve my problem.
My codebase : (I left comments on purpose to give an idea of what I have been trying so far, based on my browsing)
try {
$opts = array(
//~mrossw 'http' => array(
//~mrossw 'user_agent' => 'PHPSoapClient'
//~mrossw ),
//~mrossw 'socket' => array('bindto' => '158.69.189.149')
'socket' => array('bindto' => '127.0.0.1')

//~mrossw 'ssl' => [
//~mrossw 'verify_peer' => true,
//~mrossw 'verify_peer_name' => true,
//~mrossw 'allow_self_signed' => true
//~mrossw ]
);
$context = stream_context_create($opts);
$client = new SoapClient("https://ws_provider_hostname:xxxx/foo/bar/blah/Operaciones/OpFooBarBlahReqABCS?wsdl",
//~mrossw $client = new SoapClient($doc_root.'OpCotizadorVehiculoExtReqABCS.xml',
array(
'location' => "https://ws_provider_hostname:xxxx/foo/bar/blah/Operaciones/OpFooBarBlahReqABCS?wsdl",

);
} catch (Exception $e) {
echo \"<h2>Exception Error!</h2>\";
echo $e->getMessage();
// print_r($e);
}
The WS provider has an dev environment on port xxxx and a prod env on port yyyy. Hostname and path request are the same.
SoapClient instanciation and operation call work perfect in dev env.
When i change the port to fetch against prod env I get the following error:
SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://ws_provider_hostname:xxxx/foo/bar/blah/Operaciones/OpFooBarBlahReqABCS?wsdl' : failed to load external entity "https://ws_provider_hostname:xxxx/foo/bar/blah/Operaciones/OpFooBarBlahReqABCS?wsdl"
Provider says my public web server's IP is correctly set as allowed in their firewall. It looks right because when I tried to run the code from a different server with different IP and it fails with the same error in both dev and prod env.
When I run that code from a server inside a private network, it works in both
environment ! I don't know much about security, but this sounds to me like a security breach. I mention it here though, in case it can give a clue. I guess this is because this server has a private ip and the provider's firewall don't filter it.
When I go to https://ws_provider_hostname:xxxx/foo/bar/blah/Operaciones/OpFooBarBlahReqABCS?wsdl in my PC browser i get the correct wsdl's xml.
Do you have an idea of what can prevent the code to work form my public web server ?
Or maybe what else can I check ?
For example I couldn't find a way to check the ws server's http response code from outside my browser.
I could neither get a curl request form bash to return the wsdl xml, but that should be another question maybe.
Also let me know if i can provide any other relevant test or data.

PHP - SOAP WSDL

Currently i'm trying to build a little PHP - Soap Connector, which worked pretty good so far. But when i'm deploying my little script to my server, it won't work anymore and i have no clue, why.
I'm connecting in 2 different ways (by curling the SOAP WSDL Scheme, and saving it temporary in the script location, and creating from that a new SOAP Client, and creating a SOAP Client directly by using the SOAP WSDL Scheme URL):
$opts = array(
'http'=>array(
'user_agent' => 'PHP Soap Client'
)
);
$context = stream_context_create($opts);
// SOAP 1.2 client
$params = array (
'encoding' => 'UTF-8',
'verifypeer' => false,
'verifyhost' => false,
'soap_version' => SOAP_1_2,
'trace' => 1,
'exceptions' => 1,
'connection_timeout' => 30,
);
$curlStuff = curl_init($soapURL);
curl_setopt($curlStuff,CURLOPT_RETURNTRANSFER,true);
curl_setopt($curlStuff,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($curlStuff,CURLOPT_TIMEOUT,30);
$response = curl_exec($curlStuff);
$info = curl_getinfo($curlStuff);
if($response) {
file_put_contents("./tempSoapScheme.wsdl", $response);
}
$soapClient = new SoapClient(
'./tempSoapScheme.wsdl',
array(
'trace' => 1,
'stream_context' => $context,
'cache_wsdl' => WSDL_CACHE_NONE
)
);
$soapClientTwo = new SoapClient(
$soapURL,
array(
'trace' => 1,
'stream_context' => $context,
'cache_wsdl' => WSDL_CACHE_NONE
)
);
$result = $soapClient->myLoginMethod(
array(
'username' => 'my#email.example',
'password' => 'password'
)
);
As i said earlier - on my local machine it works like a charm, and everything is fine. The param "soapURL", which is not inside the script, is just the https path to my SOAP WSDL Scheme.
I've tried different options inside "$params" array, other curl setopt settings, but i can't make it work.
The response from both SoapClients:
SOAP-ERROR: Parsing WSDL: Couldn't load from '<MyURL>' : failed to load external entity "<MyURL>", which is pretty uncommon, because the CURL could save everything.
Do you have any suggestions for me?
EDIT - forgot the most important thing:
- The server, which should execute the script, has very strong firewall restrictions, and the SOAP URL Scheme is on another server (not the same). And i guess, that is the point, why it won't work, but i receive an answer from the Scheme by executing CURL.. So it's just SOAP?

Uncaught SoapFault exception: [HTTP] Proxy Authentication Required

Using the php Soapclient I got the exception:
Uncaught SoapFault exception: [HTTP] Proxy Authentication Required
But when using a web browser with the same proxy set up, without specifying any credentials for that proxy, I can connect getting a XML response.
The system department ensures that there is no need for authenticate. Also I'm using the SoapUI just configuring the proxy for testing porpouses, without credentials again, and I can call the methods in the WS.
Why is the php SoapClient throwing that exception? Here is the code I'm using...
$this->client = new SoapClient( null, array(
'location' => 'http://www.xxxxx.dev',
'uri' => self::URI,
'proxy_host' => self::PROXY_HOST,
'proxy_port' => self::PROXY_PORT,
) );
Following solve the exception
$this->client = SoapClient( self::URL , array(
'proxy_host' => self::PROXY_HOST,
'proxy_port' => self::PROXY_PORT,
'authentication' => SOAP_AUTHENTICATION_BASIC,
'stream_context' => stream_context_create(array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => false
)
))
));
Misunderstood with the documentation, "URI of the WSDL file or NULL if working in non-WSDL mode" and I was expecting first parameter as a file, not an URL. In some of the attempts I already tried but forgetting to set up the stream context with the SSL parameter to skip peer verification. ( probably SOAP_AUTHENTICATION_BASIC isn't necessary )
Hope it helps someone

Unable to connect to WSDL

I was working with older version of OpenSSL(OpenSSL 0.9.8o) and I was forced to use newer OpenSSL 1.0.1e-fips as the result I was unable to connect to WSDL:
Message: SoapClient::SoapClient(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
I need to disable SSL certification check, I tried:
$client = new SoapClient("https://IP:443/sdk/vimService?wsdl",
array(
"trace" => 1,
"location" => "https://IP:443/sdk/",
"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => false,
'allow_self_signed' => true,
)
)
)
)
);
`
And it throw:
Message: SoapClient::SoapClient(): Peer certificate CN=localhost.localdom' did not match expected CN=SAME IP AS IN SoapClient()'
Then I added 'peer_name'=> 'localhost.localdom', in stream_context and then it says XML file is empty:
Fatal error: Uncaught SoapFault exception: [Client] looks like we got no XML document
PHP 5.5
Okey, I was able to found issue.
You can avoid this mess using stable PHP 5.5 version
Recently I learned that error: "looks like we got no XML document" is caused because of PHP version - PHP 5.6 in 5.5 working like a charm.
How to fix it in PHP 5.6
1) Remove SSL certificate check in PHP 5.6:
In 5.6 version SSL certification was enabled by default, so if you want to disabled it you must pass context stream:
"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
)
)
)
2) Deleted ?wsdl and added .wsdl instead (with ?wsdl, it didn't worke for me)
<?php
$client = new SoapClient("https://IP:443/sdk/vimService.wsdl",
array(
"trace" => 1,
"location" => "https://IP:443/sdk/",
'exceptions' => 1,
"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
)
)
)
)
);
$soapmsg["_this"] = array( "_" => "ServiceInstance", "type" => "ServiceInstance");
$result = $client->RetrieveServiceContent($soapmsg);
$ServiceContent = $result->returnval;
$soapmsg = NULL;
$soapmsg["_this"] = $ServiceContent->sessionManager;
$soapmsg["userName"] = "USERNAME";
$soapmsg["password"] = "PASSWORD";
$result = $client->Login($soapmsg);
$UserSession = $result->returnval;
echo "User, " . $UserSession->userName . ", successfully logged in!\n";
$soapmsg = NULL;
$soapmsg["_this"] = $ServiceContent->sessionManager;
$result = $client->Logout($soapmsg);
In my case stream_context_create didn't worked.
So I download this file here : https://curl.haxx.se/ca/cacert.pem
and placed it in my localhost as : F:\xampp\apache\cert.pem
and gave the same path for
openssl.cafile=F:\xampp\apache\cert.pem in my phpini
This made the localhost to acquire certificate and things worked great...!!
Posting this in case this may help some one going through my situation.
In my case was needed to add the crypt_method
"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => true,
'verify_peer_name' => true,
'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
)
)
)
In my case "stream_context" did the magic, i've just added the code :
`"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
)
)
)`

PHP Soap call through https

i have a problem with running methods with SOAP. I'm using Apache and PHP.
this is the PHP code:
$opts = array(
'ssl' => array('ciphers'=>'RC4-SHA')
);
ini_set('soap.wsdl_cache_enabled',0);
ini_set('soap.wsdl_cache_ttl',0);
$client = new SoapClient('https://host?wsdl', array (
'stream_context' => stream_context_create($opts),
"trace" => 1,
"exceptions" => 0,
"connection_timeout"=>2000));
var_dump($client->__getFunctions());
$params = array ("key" => "value");
$result = $client->availabeFunction($params);
var_dump($result);
The __getFunctions() It returns me all of the available functions.
Then when i'm trying to call the the available function with parameters.
It returns me a strage error message:
public 'faultstring' => string 'Could not connect to host' (length=25)
public 'faultcode' => string 'HTTP' (length=4)
So i presume it is for some reasons are connecting to through the HTTP, but not through HTTPS.
I've looked up the web, and in some cases they are using a local_cert value with a .pem file.
It it neccecity to have it? Or i'm missing something else?
It's an openssl library bug.
At first try to disable SSL check by adding this params
"stream_context" => stream_context_create(
array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
)
)
)
And next try to not use ?wsdl in location link, try use something like
.wsdl
The solution was much easier as i thoguht it will be:
ini_set('soap.wsdl_cache_enabled',0);
ini_set('soap.wsdl_cache_ttl',0);
$location = 'https://host';
$client = new SoapClient($location . '?wsdl', array (
"trace" => 1,
"exceptions" => 0,
"connection_timeout"=>2000,
"location"=>$location // <- this was the reqiured parameter
));
Everything else is same as before.
This beeing cause by WSDL file configuration, that instead of https URL, it has http.
