I have a Python script that requests an https URL using the requests package. In so doing, I get a certificate error:
import requests
resp = requests.get('https://comicskingdom.com/', verify=True)
The error I see is:
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)
My system has the certifi package installed, but apparently the target server's certificate cannot be validated using that package's bundle. How can I verify this certificate properly? Where do I look to download the appropriate certificate chain? In the future, how do I know where to find the right certificate chain for any given certificate?
Solution:
requests documentation: https://requests.readthedocs.io/en/master/user/advanced/
(check args and kwargs possibilities (cert=...) in chapter SSL Cert Verification)
but to quickly resolve your issue:
(Firefox) go to your site. Click on the https icon left to the browser url (usually the icon looks like a lock),click on an arrow next to 'connection secure', click more info, click View certificates and scroll down to download Chain certificate. (You can even try here on stackoverflow site)
Then, in your requests.get, add path to the chain file
>>> requests.get('https://comicskingdom.com', verify='{path}/comicskingdom-com-chain.pem')
<Response [200]>
The certificate has some issue, so I will post here what I was able to find
What is problem?
What exactly is a problem can be found through this link or through finding the error
Source: https://security.stackexchange.com/questions/16085/how-to-get-public-key-of-a-secure-webpage
for you to examine the problem, run this command
This command will show you the certificate is ok, but there is issue
openssl s_client -connect comicskingdom.com:443 | openssl x509 -pubkey -noout
which outputs
openssl s_client -connect comicskingdom.com:443 | openssl x509 -pubkey -noout
depth=0 OU = Domain Control Validated, CN = *.comicskingdom.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 OU = Domain Control Validated, CN = *.comicskingdom.com
verify error:num=21:unable to verify the first certificate
verify return:1
Note this part
verify error:num=20:unable to get local issuer certificate
which matches requests error that I received with requests
requests.exceptions.SSLError: HTTPSConnectionPool(host='comicskingdom.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)')))

I have a pypi server, TLS server cert signed by self signed CA.
I added it as a source (default, secondary = false) to my toml file using
poetry source add mypypiserver https://server.url/
I added the CA cert using
poetry config certificates.mypypiserver.cert /path/to/ca.crt
When attempting to add external packages from pypi, such as matplotlib, even if I specify the source as pypi, I get an SSLError.
poetry add --source pypi matplotlib
Verbose logging tells me it tries to access /python-dateutil/ which results in a 303 redirect to https://pypi.org/simple/python-dateutil/.
Errors:
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)
HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/python-dateutil/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))
I suspect this is because the certificate of pypi.org does not match the self signed CA certificate.
How can this be resolved?
I need to call a web API. For that I need a bearer token.
I am using databricks(python) code to first get authenticated over Microsoft AAD. Then get bearer token for my service_user. I Followed the microsoft docs docs
But facing problem where it hits our Company server and asking for SSL certificate.
I can't install any certificate. What could be a better way to avoid it. Below is my short code taken from above microsoft and Git repos. but its not working.
Can i get help!
clientId = "42xx-xx-xx5f"
authority = "https://login.microsoftonline.com/tenant_id/"
app = msal.PublicClientApplication(client_id=clientId, authority=authority)
user = "serviceuser#company.com"
pwd = "password"
scope = "Directory.Read.All"
result = app.acquire_token_by_username_password(scopes=[scope], username=user, password=pwd)
print(result)
Got below error
HTTPSConnectionPool(host='mycompany.com', port=443): Max retries exceeded with url: /adfs/services/trust/mex (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1125)')))
The problem is that the code uses the requests library that relies on the certifi package instead of using Linux certificate chain (so existing instructions doesn't work). To solve that problem it's better to use cluster init script that will install SSL certificate when cluster starts. Something like this (requests and certifi are installed by default), just replace CERT_FILE with actual path to the .pem file with CA certificate:
CERT_FILE="/dbfs/....."
CERTIFI_HOME="$(python -m certifi 2>/dev/null)"
cat $CERT_FILE >> $CERTIFI_HOME
I am trying to scrape data from a url using beautifulsoup. Below is my code
import requests
URL = "https://bigdataldn.com/speakers/"
page = requests.get(URL)
print(page.text)
However I am getting the following error when I run the code in google colab.
SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)
During handling of the above exception, another exception occurred:
MaxRetryError Traceback (most recent call last)
MaxRetryError: HTTPSConnectionPool(host='bigdataldn.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)')))
The above code works fine for other urls.
Can someone help me figure out how to solve this issue.
It's not your fault - their certificate chain is not properly configured. What you can do is disabling the certificate verification (you should not do this when you're handling sensitive information!) but it might be fine for a webscraper.
page = requests.get(URL, verify=False)

Your SSL certificate is not installed properly , you can follow godaddy ssl install instruction maybe its helpfull .

I am using the ktrain package in jupyter with code supplied from this notebook. I get an error at the line qa = text.SimpleQA(INDEXDIR). The error is long but a shortened version is as follows:
HTTPSConnectionPool(host='huggingface.co', port=443): Max retries exceeded with url: /bert-large-uncased-whole-word-masking-finetuned-squad/resolve/main/config.json (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1125)')))

OSError: Can't load config for 'bert-large-uncased-whole-word-masking-finetuned-squad'. Make sure that:
- 'bert-large-uncased-whole-word-masking-finetuned-squad' is a correct model identifier listed on 'https://huggingface.co/models'
- or 'bert-large-uncased-whole-word-masking-finetuned-squad' is the correct path to a directory containing a config.json file
I can access https://huggingface.co/bert-large-uncased-whole-word-masking-finetuned-squad/resolve/main/config.json on my browser. I'm quite at a loss for what to do - my coding skills are minimal at best so any and all suggestions would be much appreciated.
My guess is that your corporate intranet is inserting a "man in the middle" on all https traffic. I'm guessing the following will give you the same error right now:
import requests
requests.get('https://www.huggingface.co')
If you get a CA certificate bundle from your IT department and you are on Windows, you can try this:
import os
os.environ['REQUESTS_CA_BUNDLE'] = 'path/to/certificates_ca_bundle.crt'
qa = text.SimpleQA(INDEXDIR)
If on Linux, install the certificates using these instructions.
I'm trying to access a website with httplib library but i'm getting this error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)
c = httplib.HTTPSConnection('IP', 443)
c.request(method,url);
Because the certificate is self-signed. How can I disable the certificate verification?
Thanks!
How do I have python httplib accept untrusted certs?
httplib.HTTPSConnection(hostname, timeout=5, context=ssl._create_unverified_context())
