Re: MD5 Hash Removal/Disablement DPM, Python

Here is the string I am seeing to generate a hash and it does not compare to the in response:

 

^60117415595^false^^91KEK0^P^2^Y^CC^XXXX1111^2.00^^Jane^Doe^1540 W Blue Heron Blvd^Riviera Beach^FL^33404^^^^^^^^^^^^^4156^

 

Total 31 carets and here are the fields used to compute the hash:

str_to_hash=("^" + request.POST.get('x_trans_id', '') +
"^" + request.POST.get('x_test_request', '') +
"^" + request.POST.get('x_response_code ', '') +
"^" + request.POST.get('x_auth_code', '') +
"^" + request.POST.get('x_cvv2_resp_code', '') +
"^" + request.POST.get('x_cavv_response', '') +
"^" + request.POST.get('x_avs_code', '') +
"^" + request.POST.get('x_method', '') +
"^" + request.POST.get('x_account_number', '') +
"^" + request.POST.get('x_amount', '') +
"^" + request.POST.get('x_company', '') +
"^" + request.POST.get('x_first_name', '') +
"^" + request.POST.get('x_last_name', '') +
"^" + request.POST.get('x_address', '') +
"^" + request.POST.get('x_city', '') +
"^" + request.POST.get('x_state', '') +
"^" + request.POST.get('x_zip', '') +
"^" + request.POST.get('x_country', '') +
"^" + request.POST.get('x_phone', '') +
"^" + request.POST.get('x_fax', '') +
"^" + request.POST.get('x_email', '') +
"^" + request.POST.get('x_ship_to_company', '') +
"^" + request.POST.get('x_ship_to_first_name', '') +
"^" + request.POST.get('x_ship_to_last_name', '') +
"^" + request.POST.get('x_ship_to_address', '') +
"^" + request.POST.get('x_ship_to_city', '') +
"^" + request.POST.get('x_ship_to_state', '') +
"^" + request.POST.get('x_ship_to_zip', '') +
"^" + request.POST.get('x_ship_to_country', '') +
"^" + request.POST.get('x_invoice_num', '') +
"^")

 

Let me know what am I missing?

Here is python code that generates the hash using the string with 31 carets:

 

generated_hash = hmac.new(security_tokens["SIGNATURE_KEY"].decode("hex"),
str_to_hash, hashlib.sha512).hexdigest().upper()

 

The generated hash does not match the x_SHA2_Hash response.

Respnse has this:

088B6BA3BD05C000731F6B2564B580FFA3611E56AC6CE632333F4EC5B2E4B64D74225D38BEA29C305F7C30DE7D25EF5F15E05917CF318B9362C116BA7F66F784

 

My generated hash is:

7A4BFF15533642A882CAC23B9FE5B04F62354BA4A4D1E13098BA7FD845BA6017785768CD7F0912ED23003E6323614D5AEBC05B47E892CD7518FD989213BE7C9E

 

Legnths are identical but sizes are different?

Re: MD5 Hash Removal/Disablement DPM, Python

The returned hash will always be the same size. You could hash an encyclopedia and it will still be the same size. If I could read python I would be able to nail your issue in 2 seconds. I will be on later or early tomorrow. I think you may have your items in the wrong order. Not sure.

Can you post a sample DPM html form submission? I just need one that works 100%. You can mark out your credentials and I will use mine. If you can get me that then I will be able to post the php code, and if you want, send me the exact same request you use in a test.  Python is not my strength, but I can post you a string with values and what you should get.   The hash will be the same regardless of the programming language.

Re: MD5 Hash Removal/Disablement DPM, Python

Here is a thread where I give the details of what I need. Do you get responses in silent post with DPM?

Yes. The transaction gets processed successfully. In the html I sent, you will find the needed details when you search for x_fp_sequence. I admit it is not nicely formatted. I really am confused and disappointed how authorize.net support their paying customers.

I am aware it gets posted successfully. What I wanted was a dummy form that I could copy and paste. I do not use DPM.  I went ahead and made a form from the SIM version I had before. Just a few tweaks. Will post the working code when I have time. I also replied to your message.
