I am running python 3.9.1 I have some Django Admin Actions which create and then download some PDFs. When running this on my local machine (Windows 10) I have recently started getting the following error message:
SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1123)
Any ideas on how I can deal with this? The Django app works perfectly on the server, the problem is only on my local host.
In my case, I was interacting with IoT (Internet of Things) device APIs and had a LetsEncrypt certificate that expired. I downloaded the new LetsEncrypt cert at: https://valid-isrgrootx1.letsencrypt.org/
More explanation:
My error occurred on a Windows Python client requesting API information from an IoT web server. I determined which client certificate was expired by viewing existing certificates dates in Windows:
Open Powershell as admin, then: Get-Childitem cert:\LocalMachine\root |format-list
The expired cert was owned by LetsEncrypt. More information about the expired cert: https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/.
In my case, the LetsEncrypt root certificate expired at the end of September and was replaced with the newer cert going forward. To implement the new cert, visit any webpage that uses that certificate from your failing client. In the case of LetsEncrypt, visit their cert demo page at: https://valid-isrgrootx1.letsencrypt.org/, and your certificate store will update automatically.

I am running a localhost application on flask. I created a self signed certificate and imported it to the trusted root certification authorities in google chrome. Below are images showing after effect of trusting these certificates. However, whenever i browse to the localhost site, i am still met with the not secure tag.
I'm trying to request some data from a website using suds in Python. I'm getting urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)> while creating suds client. I do not get this error when I'm running the project locally but this issue happens when I try to deploy this project to a Linux host so that it can be automated.
One thing to note is, this python code lies behind AppProxy so that it can connect to internet. I have verified using a CURL request that the remote hosts is able to connect to the website.
I'm new to SSL Certificate thing not so sure about this certificate issue, do I need to install any server certificates on the hosts so that it can verified by SSL Validation? Any leads would be helpful. Thanks.
When setting up my Kafka Client locally on my mac without specifying ssl.ca.location, it works. But when I run it on a docker container locally I get the error: Failed to verify broker certificate: unable to get local issuer certificate. How can I solve this?
driver_options = {
'bootstrap.servers': kafka_brokers_sasl,
'sasl.mechanisms': 'PLAIN',
'security.protocol': 'SASL_SSL',
'sasl.username': 'token',
'sasl.password': api_key,
'log.connection.close' : True,
#'ssl.ca.location': ''
}
I have seen multiple proposals for trying this, for example this solution: https://github.com/henadzit/cloudkarafka-test-project, but can't get it to work.
Failed to verify broker certificate: unable to get local issuer certificate
Indicates that librdkafka is not able to find the root CA certificate on the server. Normally you have two options:
You either let librdkafka locate the certificate on the host
or you can specify the location of the certificate
Docker images though, are usually unable to locate the CA certificate so you can either install it on the image or specify its location in librdkafka's configuration
To do so, you need to specify ca-cert's location in ssl.ca.location
EDIT:
In order to create certificates you can follow Confluent's Security tutorial which is a step-by-step guide.
In order to encrypt with SSL on Kubernetes you can use kube-lego
I am stuck on this step of the APNs (Apple Push Notification) process. I have app-specific certificates and keys from developer.apple.com that work fine for a local dev server on my OSX system, but on my RHEL based OpenShift cloud servers they don't seem to work. There is this cryptic step from Apple's documentation.
https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/CommunicatingWIthAPS.html#//apple_ref/doc/uid/TP40008194-CH101-SW1
Note: To establish a TLS session with APNs, an Entrust Secure CA root certificate must be installed on the provider’s server. If the server is running OS X, this root certificate is already in the keychain. On other systems, the certificate might not be available. You can download this certificate from the Entrust SSL Certificates website.
I did obtain said certificate, as both a .der and .cer from this site.

Now where do I put them? I am running a Django app (might switch in the future, but a separate topic) on OpenShift.
If you want to send apple push notifications from a shared server or PaaS , you will probably have to use a third party such as http://urbanairship.com/.
Hi I am new to SSL and I am trying to connect to an IIS ASP.NET web server which has issued to me a unique .pfx certificate to verify me to the server.
Using a browser where I have installed the certificate I am able to connect the site where I have to upload a file on a daily basis.
I am trying to write a python script to do the same task. I have tried to use the Python Mechanize library.
While adding certificate I converted the .pfx file to .key and .cer PEM file so that it could be attached to add_client_certificate method, but later, I found out that IIS server accepts only .pfx certificate and there is no way to attach a .pfx certificate directly to the Mechanize browser instance.
Is there a way or another library where I can do this task?
You can use requests library
import requests
requests.get("https://your_server", cert=('client01.cer', 'client01.key'))
