Thalse hsm communication

[Kapilashantha Rajapaksha]

Is it possible to use Q2 server to keep persistent socket connection with Hsm an proceess async calling.?

Appreciate any direction from experts 

[Alejandro Revilla]

We've impleented drivers for most HSMs (Atalla, Thales, Utimaco, Futurex, etc. and cloud HSM offerings) using Q2.

Because the specs are not public, this code is not open source, but it can certainly be done. We use them as part of jCard/jPTS.

Thanks for your reply and got it.  So i guess that i have to look my own way right?

Talk to the hsm using a mux by determining which field to match on for request response matching, we use the header with an incremental counter that is echoed back by Thales. 

A mux can do an asynch request.

For this, I can use  first 4 bytes (header), it will respond  with the same header. But when I check mux, the package always iso message. Can mux use any non-standard protocols ?

Look for FSDISOMsg, I believe there are some threads about that in the list.

Hi Chhil,

I'm looking at mentioned post. 

HSMChannel class I couldn't find with jpos lib (latest).

Thanks

[Mark Salter]

Which Channel are you currently talking to your HSM through?  Use that
instead?

[Kapilashantha Rajapaksha]

Hi Mark,

I'm currently not calling to hsm, this effort to do from jpos lib,

as per Chhil code, I cannot find out hsm packager in jpos lib now

[Andrés Alcarraz]

You don't need that class, that part of the post is not the answer, but the question.

You need to look for the part where the channel to talk to the HSM is defined (21_hsm_channel.xml), in the participant you can would need to use the mux, not the channel.

The answer will not provide a complete working example, just read through it and understand the concepts.

[Andrés Alcarraz]

BTW, you will still need to implement the FSD schema for talking to the HSM.

I can’t see how FSDMsg.pack() can return a null.

Could you share that project (that I guess is just a POC without sensitive info) as a packaged file or, better yet, through git? So you make us easier to help you than having to create the project and every single file to reproduce?

Hi Alcarraz,

Hi Rajapaksha,

It seems that |FSDChannel| assume it is always configured through
|setConfiguration|. So when you just use the default constructor it
initializes with a null |charset| wich is what is causing the NPE. A
simple workaround would be to call |channel.setConfiguration(new
SimpleConfiguration())| just after the call to the default constructor:

|public ThalesAdaptor(String host, int port) throws
ConfigurationException { channel = new FSDChannel();
channel.setConfiguration(new SimpleConfiguration());
channel.setHost(host, port); channel.setPackager(new FSDPackager()); } |

This won’t happen in the real project when you use Q2 to initiate
everything, which I encourage you to do as early as possible, i.e., as
soon as this first POC works. I will try to create an issue and a PR to
fix this.

I couldn’t test the receive part since I don’t have an HSM to connect
to, and I don’t want to set up a simulator or an echo. Also, you don’t
need to create the response in your adaptor, the channel will create it
for you. I believe you need to also set the schema for the response,
which I think you can do by adding it to the configuration object for now.

Did you change these two lines at all :-

    FSDMsg req = new FSDMsg("file:cfg/hsm-");

	FSDMsg resp = new FSDMsg("file:cfg/hsm-resp-");

If so, what to?

I think these should be the correct URL form for a file:// and need to resolve relative to the current runtime directory location.  
Check the documentation.

Hi Mark,

I changed and try 

private FSDMsg createRequest(String command) {
    FSDMsg req = new FSDMsg("file://cfg/hsm-");

    if (command != null)
        req.set("command", command);

    return req;
}

private FSDMsg createResponse(String response) {

    FSDMsg resp = new FSDMsg("file://cfg/hsm-resp-");

    if (response != null)
        resp.set("response", response);

    return resp;
}

But now i'm getting below error in packing (not receiving any message to hsm server side )

HI Alcarraz,

"I couldn’t test the receive part since I don’t have an HSM to connect to, and I don’t want to set up a simulator or an echo. Also, you don’t need to create the response in your adaptor, the channel will create it for you. I believe you need to also set the schema for the response, which I think you can do by adding it to the configuration object for now."

Can you give me some direction, i tried many options but still was not able to do success? 

Example 

Properties props = new Properties ();
props.put ("basepath", "file:cfg/hsm-");
props.put ("host", "localhost");
props.put ("port", "1700");

The properties from the link should work (https://groups.google.com/g/jpos-users/c/T5tuRMB1jXk/m/IJ2h5Q6CAgAJ)

<property name="schema" value="file:cfg/hsm-resp-" />

Deploy a FSDChannel. And configure the path to the hsm schema file. Remember that a single schema file is configured to pack requests and unpack responses. Your schema has one hsm-base for requests and one hsm-resp-base for responses.

https://github.com/jpos/jPOS/blob/master/jpos/src/main/java/org/jpos/iso/channel/FSDChannel.java

See if you can have one base file 

hsm-base.xml

Rename hsm-resp-ND.xml to hsm-ND.xml and change its content to 

<?xml version="1.0" encoding="UTF-8"?>

<schema id='ND'>

<field id="error" type="A" length="2" />

<field id="lmk-check-value" type="A" length="16" />

<field id="firmware-number" type="A" length="9" />

</schema>

So this way you have a single schema that handles requests responses.

Now let this handle both requests and responses.

So a NC/ND pair can be handled by this.

You can add a counter to the schema for the header to get echoed back and use that in the mux.

So the base will have something like the following as the first field.

<field id="header" type="N" length="4"/>

[chhil]

When you see a Nested:java.io.FileNotFoundException: cfg\hsm-null.xml

it implies while parsing the message it did not find the command specific schema file.

So if you sent NC and got back a ND it will look for the hsm-ND.xml file.

Your schema does not include the 4 digit 1234 that you are getting. So its seeing 12 and looking for the xml schema hsm-12.xml and it cannot find it.

Include the header definition  as the first field of the base file.

Hi Chhil,  

thanks for help but i have seen this behavior 

<?xml version="1.0" encoding="UTF-8"?>
<schema>

    <field id="header" type="N" length="4"/>

    <field id="command" type="A" length="2" key="false" />

if key ="false" no any error 

but result like below

You should start debugging the pack and unpack routines for fsdmg.

The test pack and unpack looks fine at the FSDMsg level in the the following test code. 

FSDMsg m = new FSDMsg("file:/blah/jpostest/hsm-");

m.set("command", "NC");

System.out.println(m.pack());

m = new FSDMsg("file:/blah/jpostest/hsm-");

String resp = "1234ND00336065001064661126151500-0"; // See output, firmware gets cut. Need to adjust size.

m.unpack(resp.getBytes());

m.dump(System.out, "");

Output

0000NC

Hi Chhil,

I manged to unpack response with below code 

 byte [] buffer = new byte [100];
  byte [] buffer2 = new byte [100];

  FSDISOMsg rep = new FSDISOMsg(resp);

// ISOMsg m =  channel.receive();
  channel.getBytes(buffer);
  System.out.println(ISOUtil.hexdump(buffer));
  System.arraycopy(buffer, 2, buffer2, 0, buffer.length - 2);
 // System.out.println(ISOUtil.hexdump(buffer2));
  resp.unpack(buffer2);

Can't we use below directly but it's returns IsoMsg?

channel.receive();

[Mapfunde Venon]

you can define the response schema as well like you did the request eg:

request. hsm-NC.xml

<?xml version="1.0" encoding="UTF-8"?>
<schema id='NC'>
</schema>

response: hsm-ND.xml

<?xml version="1.0" encoding="UTF-8"?>
<schema id='ND'>
    <field id="error"       type="A" length="2" />
    <field id="lmk-check-value" type="A" length="16" />
    <field id="firmware-number" type="A" length="9" />
</schema>

Hi my question how can use below 

channel.receive()

Without manually copy because it's not returning FSDmsg

Thanks 

[Mapfunde Venon]

Try this :

FSDISOMsg response = (FSDISOMsg)channel.receive() 

if (response != null) {
    return ResponseEntity.ok(response.getFSDMsg().getMap());
} else {
    return ResponseEntity.ok(tx.getFSDMsg().getMap());
}

not sure if that will work because i use a mux to send requests not directly through a channel like you are doing

Did you set the schema in the channel?

I cannot tell you, other than writing test snippets that use channels, I don't ever access channels directly.

You started off this thread wanting to do  asynch HSM communication, and you are trying to use the never recommended method of channels.

Hi Chhil, 

Yes , I'm agreed but just i wanted to know behavior of FSDmsg but now I tried to use Q2 and MUX but it seems like not deploying mux.xml file in my deploy folder 

mux.xml

<mux class="org.jpos.q2.iso.QMUX" logger="Q2" name="mymux">

<channel-adaptor class="org.jpos.q2.iso.ChannelAdaptor" logger="Q2" name="HSMChannel">

        <property name="port" value="1700" />


    </channel>
    <in>hsm-send</in>
    <out>hsm-receive</out>

new Q2().start();
Thread.sleep(20000);
QMUX qmux = (QMUX) NameRegistrar.getIfExists("mux.my");

However below is returning null value 

QMUX qmux = (QMUX) NameRegistrar.getIfExists("mux.my");

Let me know what's wrong with me

I had to add below line (additionally in request , any workaround for that ?  )

  request.set("0", "0200");

I can see full response as below but getting exception too 

I suspect  something  wrong here.  Appreciate your advice ? because res is null

Not sure if this is the reason but you have copy pasted the code. You do not have a field called "response", you replaced it with "command" to unify the request rsp schemas.

FYI, you don't have to sleep for 20 seconds. Instead, you can use NameRegistrar.get("mux.my", 20000L). This way, if the MUX becomes available before the 20-second wait—which it most likely will be—you can speed up your startup time.

hi Chhil 

 I changed hsm-ND.xml  and hsm-NC.xml as below 

<?xml version="1.0" encoding="UTF-8"?>

<schema command='ND'>

    <field id="error" type="A" length="2" />

<?xml version="1.0" encoding="UTF-8"?>

<schema command='NC'>
</schema>

And code 

private FSDMsg createResponse(String response) {
    FSDMsg resp = new FSDMsg("file:cfg/hsm-");

    if (response != null)
        resp.set("command", response);

    return resp;
}

}

public FSDMsg command(FSDMsg request) throws Exception {
    StringBuffer sbuffer = new StringBuffer(request.get("command"));
    sbuffer.setCharAt(1, (char) (sbuffer.charAt(1) + 1));
    FSDMsg resp = createResponse(sbuffer.toString());

    FSDISOMsg msg = new FSDISOMsg(request);

    request.set("stan", "1234");
    request.set("0", "0200");
    System.out.println(ISOUtil.hexdump(msg.pack()));

    QMUX qmux = (QMUX) NameRegistrar.getIfExists("mux.hsm-mux");

    FSDISOMsg rep = new FSDISOMsg(resp);

    rep=  (FSDISOMsg)qmux.request(msg,5000);
     return rep.getFSDMsg();

rep=  (FSDISOMsg)qmux.request(msg,5000);  

I have noticed that rep is NULL

My concern why it's validating MTI  (without  request.set("0", "0200"); it's not getting reply as well )

 Hi Alejandro, 

Thanks for the information and already applied 

Look for your advice to resolve this (I have seen same issue here-QMUX not able to work with FSDMsg without MTI · Issue #428 · jpos/jPOS · GitHub but it does not work for me)

Put breakpoints and start debugging jpos code to figure out what's going on, is all that I can recommend.

Hi Chhil ,

Finally I was able to communicate with HSM . 

Below is the approche I worked around and helpful to others too.

Excellent!
Maybe point out what you fixed so that someone doesn't have to go through your various iterations of files and code to figure out would be helpful. Thanks.

I override below 

=====================================================

public class HSMChannel extends FSDChannel {
public HSMChannel() {
super();
}
@Override
public ISOMsg createMsg() {
FSDMsg fsdmsg = new FSDMsg ("file:cfg/hsm-");

return new HSMsg(fsdmsg);
}


}

=================================================================

[chhil]

       String command = getFSDMsg().get("command");

        if (command==null){
            return getFSDMsg().get("command");
        }

The command==null check does not make sense. You don't need it.
Both your request and response based off a single base schema have command in it, and it can only be null if the message only had the stan. It made sense when the schemas were different for request/response, where request had a "command" field and response had a "response" field.
I think most people have used separate schemas for req/rsp as those were what were floating around including the hsm code :).
I do think using a unified single schema makes most sense.
