Hi team, I am working on portal.py. I am trying to get the details of SSL certficates which the portal is using. I have tried with some code but nothing is working. Any suggestion on this will be helpful. import sys sys . path . append ( '..' ) import portalpy import csv import ssl , socket portalUrl = " https://xyz-xyz.xyz.xyz.com:7443/arcgis " portalAdminUser = "xyz" portalAdminPassword = "xyz" portal = portalpy . Portal ( portalUrl , portalAdminUser , portalAdminPassword ) users = portal . search_users ( '(role:account_admin OR role:account_publisher OR role:account_user)' ) activeUser = portal . logged_in_user ( ) print activeUser [ 'email' ] ctx = ssl . create_default_context ( ) s = ctx . wrap_socket ( socket . socket ( ) , server_hostname = ' http://xyz-xyz.xyz.com/arcgis/home/ ' ) s . connect ( ( portal , 443 ) ) cert = s . getpeercert ( ) print cert Thanks Aditya Kumar

Joshua, I was able to run this in the Pro python window, but had to add ( ) around the print string. Based on things I've read on one of Dan's /blogs/dan_patterson/2016/05/09/the-links?sr=search&searchId=a1012d53-da1f-4df7-b109-573165a00e62&searchIndex=3 blogs, that is a requirement for the 3.x python flavors. So, yours is the correct answer, but here it is with the change import ssl , socket hostname = 'geonet.esri.com' ctx = ssl . create_default_context ( ) s = ctx . wrap_socket ( socket . socket ( ) , server_hostname = hostname ) s . connect ( ( hostname , 443 ) ) cert = s . getpeercert ( ) props = [ ] props . append ( ( 'Valid from' , cert [ 'notBefore' ] ) ) props . append ( ( 'Valid to' , cert [ 'notAfter' ] ) ) props . append ( ( 'Serial number' , cert [ 'serialNumber' ] ) ) for name , value in props : print ( "{: . format ( name , value ) ) I was able to successfully run this against my own hostname. thanks.

It failed to connect. Tried the same.

RebeccaStrauch__GISP

I tried that and got an error from line 4

import ssl, socket

hostname = 'mySite'
ctx = ssl.create_default_context()

Traceback (most recent call last):
Python Shell, prompt 6, line 4
AttributeError: 'module' object has no attribute 'create_default_context'

RandyBurton

I used hostname = 'google.com' in line 3 of bixb0012‌'s code, added a couple of print statements and had no issues obtaining google's info.

I would suggest just using your base domain "xyz.com" (from your sample code - with no "https://xyz.x....") for the host in line 3 of Joshua's code. You may need to use port 7443 instead of 443 in line 6.

ADITYAKUMAR1

Thanks a lot Randy Butron and Joshua. It really helped and its working.

RebeccaStrauch__GISP

For my machine, it must be another issue. For me, even after importing the ssl, it doesn't find

ssl.create_default_context

and never gets to the next line. Using Wing Pro 5.1.12-1 python shell and ArcCatalog python window. Somehow I must be getting an incorrect version of ssl ?? the ssl comes up in the intellisense (i.e. other ssl attributes work), but not the create_default_context. Not critical for my work right now so I won't spend a lot of time figuring it out on my system, but it does sound like a nice tool.

RandyBurton

From github, ssl.create_default_context was added in 2.7.9. I also received the same error as you when using Python 2.7.5.

ADITYAKUMAR1

I was able to get al the details. But I am not able to segregate the details. Like expiry date,issued date,serial number.

Any idea?

JoshuaBixby

If you are using 2.7.9 or later, the examples already provided will get you the information you want. The cert information is returned as a dictionary containing a mix of tuple, Unicode, string, and long; so you just need to explore the structure of that dictionary to know which keys and values to work with.

Using GeoNet as an example:
