Notice that you're using HTTPS
. As mentioned in the Requests manual
To check a host’s SSL certificate, you can use the verify argument [...] By default, verify is set to True
Here are few ways to fix that:
Update OpenSSL (probably will solve your problem)
Taken from here:
If you encounter one of the following errors:
error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm
error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm
The software you are using might be compiled with a version too old of OpenSSL that does not take certificates signed with sha256WithRSAEncryption into account.
It requires at least OpenSSL 0.9.8o for a total management of SHA256. OpenSSl 0.9.7m only assures a partial management, for server
mode only.
Check your openssl
version by
openssl version
OpenSSL 1.0.1k-fips 8 Jan 2015
If you have a smaller version than OpenSSL0.9.8o
, you have to update its version (OS X):
brew update
brew install openssl
brew link --force openssl
If that doesn't work, try this way:
brew uninstall openssl
rm -rf /usr/local/openssl
brew install openssl
- there's an issue with
openssl
installed before OS X 10.10.3
and reinstalling it fixes it
- these command lines will uninstall
openssl
, remove its folder from your hard-disk and install it again (the updated version)
Install certifi
Taken from here
By default Requests bundles a set of root CAs that it trusts, sourced
from the Mozilla trust store. However, these are only updated once for
each Requests version. This means that if you pin a Requests version
your certificates can become extremely out of date.
From Requests version 2.4.0 onwards, Requests will attempt to use
certificates from certifi if it is present on the system. This allows
for users to update their trusted certificates without having to
change the code that runs on their system.
For the sake of security we recommend upgrading certifi frequently!
In other word, try to install certifi
, if you have Request 2.4.0
or newer:
pip install certifi
Hopefully, this will fix the problem.
Use different version of OpenSSL and Requests
Looking into it using Google, I have found that there is a problem with OpenSSL in Python 2:
However, I am using Python 2.7.6
, Requests 2.2.1
and OpenSSL 1.0.1f 6 Jan 2014
and everything runs correctly.
Pass the certificate
In other cases, you may need to tell requests.get
the path to the certificate file, if the host's certificate was signed by you.
requests.get("https://api.github.com/events", verify=True, cert=['/path/to/my/ca.crt'])
Set the verify argument to False (NOT RECOMMENDED!)
In case you want to avoid the certificate verification, you have to pass verify=False
to the request.get
method.
python -c 'import requests; requests.get("https://api.github.com/events", verify=False)'
or from script.py
file:
import requests
res = requests.get("https://api.github.com/events", verify=False)
print res
terminal:
$ python script.py
