docker-compose run --rm genquote bash

Generate quote

./run-client -q --debug

Copy quote

Sending the quote to IAS

ipython

Set request body:

json = {"... copied quote ..."}

Set request headers:

import os

headers = {
    'Content-Type': 'application/json',
    'Ocp-Apim-Subscription-Key': os.environ['IAS_PRIMARY_KEY'],
}

Send the quote to Intel:

import requests

url = 'https://api.trustedservices.intel.com/sgx/dev/attestation/v4/report'

res = requests.post(url, json=json, headers=headers)

Check the response status:

res.ok

Display response:

res.json()

Extract report body:

import base64

isv_enclave_quote_body = res.json()['isvEnclaveQuoteBody']
report_body = base64.b64decode(isv_enclave_quote_body)[48:432]

Check the MRENCLAVE:

report_body[64:96].hex()    # mrenclave
# a6407626cc7c28cddff44a5d710a1810244237326e6037cf813b2baf86470892 

Extract the REPORT DATA:

report_body[320:384].hex()  # report data
# 661442fb3d8f47095f7886600aa3075935e155e27d3e021838e7caf69e4bf5260000000000000000000000000000000000000000000000000000000000000000

Let's "re-do" the computation, to verify the result:

import hashlib

s = b'Hello World!'

# this may take a minute or so
for _ in range(1000000):
    s = hashlib.sha256(s).digest()

report_body[320:384][:32] == s
# True
