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 “=”.

3. 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.
