SSO
13

I’ve tried to apply this but can’t get it to work. Below is some (simplified) Python code that generates a url for .../session/sso_provider. When I try it, I get Login Error. No idea what that means.

import secrets
import base64
import urllib.parse
import hmac
import hashlib

forum_url = 'https://forum.embeetle.com'
target_url = 'https://embeetle.com/#account'
sso_secret = b'JCLSVcqbAnEPXz2p2xBY'

nonce = secrets.token_urlsafe()
payload = f'nonce={nonce}&return_sso_url={target_url}'
payload_base64 = base64.b64encode(payload.encode('utf-8')).decode()
payload_for_url = urllib.parse.quote(payload_base64)

payload_for_url = 'bm9uY2U9YklKeEU1WWw2OFhjSkJydGlwSU15UTRZeVlMeWd6ZzQyUU9mOFo0SWF5QSZyZXR1cm5fc3NvX3VybD1odHRwczovL2VtYmVldGxlLmNvbS8jYWNjb3VudA%3D%3D'

signature = hmac.new(
    sso_secret, payload_for_url.encode('utf-8'), hashlib.sha256
).hexdigest()

print(f'{forum_url}/session/sso_provider?sso={payload_for_url}&sig={signature}')

For example, one run might generate the url in the curl command below:

johan@morla:~/sa\> curl 'https://forum.embeetle.com/session/sso_provider?sso=bm9uY2U9YklKeEU1WWw2OFhjSkJydGlwSU15UTRZeVlMeWd6ZzQyUU9mOFo0SWF5QSZyZXR1cm5fc3NvX3VybD1odHRwczovL2VtYmVldGxlLmNvbS8jYWNjb3VudA%3D%3D&sig=a392ebb81b93ba7411290fbd00240921ae053bbb82998830dda994c8a71853da'
