MD5 Hash Removal/Disablement DPM, Python

[ Edited ]

We are using Python with DPM post option. Followed the hash upgrade link instructions from here:



DPM post fails with "This transaction cannot be accepted." Not getting additional clues and the failed transaction is not visible in Sandbox.


I am stuck and don't know how to proceed. Need a clear example for the following:


1. How to generate the SHA512 hash in Python

2. How to verify the returned hash in Python


Here is what I tried for #1 above that results in failure:


 fingerprint =["SIGNATURE_KEY"]),
"^"+security_tokens["LOGIN_ID"]+"^"+self.seq+"^"+ts+"^"+self.amount+"^", digestmod=hashlib.sha512).hexdigest()


When I do a DPM post with this generated hash in x_fp_hash, I get  "This transaction cannot be accepted."


Still don't know the exact python code to verify the returned SHA512 hash (#2).


Example code snippets in Python is much appreciated.



Also when I copied the signature key to clipboard, I noticed an extra carriage return in the beginning. However, I used the characters after the carriage return. Not sure if that has any impact?
