I'm trying to use aio-pika to establish a secured connection to rabbitmq, while disabling certificate verification.
According to the documentation you can pass both ssl boolean flag, and ssl_options dictionary.
I tried passing both, specifying ssl_option with no certificate, but it still fails.
connection = await connect_robust(
host=self.host,
virtualhost=self.rmq_vhost,
port=int(self.rmq_port),
login=self.rmq_user,
ssl=True,
ssl_options=None, # also tried dict(cert_reqs=ssl.CERT_NONE),
password=self.rmq_pass,
loop=main_loop)
The received error is:
[Errno 1] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for '10.0.0.1'. (_ssl.c:1122)
https://aio-pika.readthedocs.io/en/latest/apidoc.html?highlight=ssl#aio_pika.connect_robust
I do not want to (and cannot) change the server configuration. Would like to do it on the client side. I'm able to disable it and connect fine with programs written in other languages (typescript, .Net).

I'm trying to implement mutual authentication on a ftps connection using ftplib module.
Here is my code:
Context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
Context.load_verify_locations(cafile=trusted.txt,capath=path)
Context.load_cert_chain(certfile=mycert.txt,keyfile=mikey.txt,password=xxxx)
Context.verify_mode=True
Ftp = ftplib.FTP_TLS(Context=Context)
Ftp.connect(host, port)
Ftp.auth()
Ftp.prot_p()
Ftp.set_pasv(True)
Ftp.cwd(dest_dir)
Ftp.storlines(xx,xx)
Ftp.close()
However above works fine only with client authentication set as no on ftps server side. When we try with client Auth yes
Error code is as below.
Ssl.SSLError: [SSL:SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert certificate unknown (_ssl.c:777)
I have the servers cert chain on ca file defined.
I have my trusted on servers side defined.
Still connection doesn't work well. And it works well if client Auth is disabled on server side.
Any suggestions on what could be wrong. Could it be ciphers?
I tried setting up ciphers but don't know how exchange happens in realtime. Or could this be that ftplib does not support fully mutually authentication at all??
Ssl.SSLError: [SSL:SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert certificate unknown (_ssl.c:777)
If you get this error in the client then the server failed to validate the client certificate, i.e. your mycert.txt and mikey.txt.
Since validation of the client certificate is done by the server you have to look at the server configuration and logs for more information of why your client certificate was not accepted. Typical problems are that the client certificate is a self-signed certificate, that the CA which issued the client certificate is not trusted in the server or that intermediate certificates are required to verify the certificate but the client is not sending these.
I'm using asyncpg to connect my database in Heroku postgresql, using python:
import asyncpg
async def create_db_pool():
bot.pg_con = await asyncpg.create_pool(dsn="postgres://....", host="....amazonaws.com", user="xxx", database="yyy", port="5432", password="12345")
it was working perfectly until I received an email from heroku advising me of a maintenance: Maintenance (DATABASE_URL on myappname) is starting now. We will update you when it has completed.
then this error appeared:
asyncpg.exceptions.InvalidAuthorizationSpecificationError: no pg_hba.conf entry for host "123.456.789.10", user "xxx", database "yyy", SSL off
I tried to follow some help, like putting ssl=True
but this error appeared:
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1108)
same as putting ssl="allow"
asyncpg.exceptions.InvalidPasswordError: password authentication failed for user "xxx"
what can I do to fix this?
Using the solution from this worked.
import ssl
ssl_object = ssl.create_default_context()
ssl_object.check_hostname = False
ssl_object.verify_mode = ssl.CERT_NONE
# connect elsewhere
pool = await asyncpg.create_pool(uri, ssl=ssl_object)
Note: You don't need to use any certificate like mentioned in the comment, as we set verify_mode to not use certificates.
I'm trying to send a GET request to a host with (supposedly) correct certificates.
It's a university task, and they gave me these certificates. (which are only valid for 30 seconds)
But the code below gives me the error that certificate verify failed: self signed certificate
The package I got from the host in response says that Fatal Error: Unknown CA.
What could cause the issue? Thanks!
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
context.load_cert_chain('clientcert.pem', keyfile='clientkey.pem')
connection = http.client.HTTPSConnection(IP)
connection.request("GET", "/")
response = connection.getresponse()
print("response:", response)
The error message seems to be self-explanatory. Self-signed SSL certificates always cause security warnings/errors. You will either need to add your self-signed SSL as an exception or add the self-signed CA to OS trusted certificates pool.
You may also try using something identical to --insecure option in curl.
I'm trying to solve the problem
requests.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)
when I connect to a handle server.
I also used
ssl._create_default_https_context = ssl._create_unverified_context
as some user suggested, but I'm not able to fix the issue.
Any other solution?
Thanks
Does your server have a valid certificate, signed by a Certification Authority?
If it uses a self-signed certificate I would suggest that you save a copy of the public certificate in your Python project and pass the certificate name in the verify parameter on requests.
You can save the certificate by accessing the server on Firefox, clicking on the Lock icon near to the address bar, selecting the Certificate, then More details, then View Certificate, then export.
You will get a .pem file, let's say: "my_server_certificate.pem".
Then when you create your Session object on requests you can pass the parameter:
session = requests.Session()
session.verify = "my_server_certificate.pem"
I had similar problems when using charles proxy with my Python scripts. I hope this helps you solve your problem as well.
I have a python script that uses the VirusTotal API. It has been working with no problems, but all of a sudden when I run the script I am getting the following error:
urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>
I believe it may be our web proxy that is causing the issue. Is there a way to prevent it from verifying the cert? Here is the portion of the code that uses the API:
json_out = []
url = "https://www.virustotal.com/vtapi/v2/file/report"
parameters = {"resource": my_list,
"apikey": "<MY API KEY>"}
data = urllib.urlencode(parameters)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
json_out.append (response.read())
I believe it may be our web proxy that is causing the issue. Is there a way to prevent it from verifying the cert?
If you assume that a SSL intercepting proxy is denying the connection then you have to fix the problem at the proxy, i.e. there is no way to instruct the proxy to not check the certificate from your application.
If instead you assume that there is a SSL intercepting proxy and thus the certificate you receive is not signed by a CA you trust then you should get the CA of the proxy and trust it in your application (see cafile parameter in the documentation). Disabling validation is almost never the right way. Instead fix it so that validation works.
There are two possibilities,
You are using a self-signed certificate. Browsers don not trust on such certificate, so be sure that you are using CA-signed trusted certificate.
If you are using CA-signed trusted the certificate that you should have to check for install CA chain certificates (Root and Intermediate certificate).
