+The **sign_message_standard_ops** function verifies with [RanchiMall standard operations](https://github.com/ranchimall/Standard_Operations).
+Things to note:
+The function now takes 2 parameters -
+
+1. Message in string ( not hex-encoded string)
+2. Private key in wif (not bytes etc.)
+The hex parameter has been removed as we are always returning hex in standard ops
+
+New libraries used - hashlib
+The elliptical curve folder, holds the code taken from starkbank ecdsa (MIT License)
+no other additional dependencies
+
+The signature generated with **sign_message_standard_ops** cannot be verified using purely Pyflo. Users can use the following API to verify signatures 
+
+** Python **
+``` 
+import requests
+
+url = 'https://flo-sign-validator.duckdns.org'

+            'sign': sign}
+
+x = requests.post(url, json = myobj)
+print(x.text)
