Request
Sign: Use the public key provided by intella for verification (Please note: use the correct public key for staging/production server).
Signature Verification
Remove the “Sign” filed from the original response JSON. Save the content of the “Sign” filed for step 2.
Do a base64 decode of the content of the “Sign” field. Replace the unicode-encoded characters with their original ASCII characters prior to the base64 decode. For example, replace "\u003d" by “=”.
Verify the JSON data from step 1 with the sign data from step 2 by the RSA public key provided by intella with SHA256 algorithm.
