What is an SSL Certificate?
SSL is a digital certificate that helps websites and applications establish an encrypted and secure connection with web browsers. It is the standard technology to keep the internet connection secure and encrypted and to safeguard any sensitive data exchange between any two nodes.
An SSL Certificate aims to keep the data secure and prevent hackers from reading and modifying the data or information.
To give you a better understanding of what SSL is, look at the below image:
The URL https://guidingcode.com/ has an s after the HTTP, meaning this website is SSL certified, and you can share data and information with it. Another thing to note is the padlock, it also indicates that the website is SSL certified.
Keep these indications in mind, and avoid interacting with unsecure sites. The URL of an unsecured website does not contain the s after HTTP instead, it is just HTTP.
What Are the Causes of the SSL Certificate Verify Failed Error in Python?
There could be numerous reasons behind the SSL certificate verification error you encounter when using Python. I’ll discuss a few most common causes and solutions that could help you solve the SSL certificate issue.
The following are the potential causes of this Python error:
- Not using a valid SSL certificate. Hence, make sure to use a valid SSL certificate. Otherwise, your data will neither be secured nor encrypted (Warning emoji).
- The web browser does not recognize the website’s SSL certificate. So, make sure to use the SSL of a verified and reputable company.
- The rise of SSL: Certificate verify failed error, and the reason for this error is either the SSL version being outdated or the subscription of SSL expired. Either update it through the command line interface (CLI) if it’s the version issuing; otherwise, renew your subscription.
- Using an outdated version of Python. Therefore, make sure to keep an eye on your Python version. Python 3.4.1 and earlier versions do not use to validate the certificates by default, so make sure to validate it manually.
How to Fix the SSL Certificate Verify Failed Error?
As we discussed in the reasons above that the reason could be the outdated version of your SSL certificate. The obsolete version might give you a tough time, but no worries, you can utilize the below commands to update and upgrade the certificate to fix the error.
Head on to your 👨💻 command line interface (CLI) and enter the following commands
\# Update pip pip install --upgrade pip
Before updating your SSL certificate, first, make sure you have the latest version of pip. And then, you can edit the certificate.
# Update your certificate pip install --upgrade certifi
This will help you install the certificates, but if you want to reinstall the SSL certificate for a specific reason instead of updating it, you can use this command.
# reinstall certificate instead of updating pip install --upgrade certifi --force-reinstall
pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <package_name>
The above command will add trusted hosts to your Python program, but if you want to add these to your config file, you can do it as follow;
pip config set global.trusted-host \ "pypi.org files.pythonhosted.org pypi.python.org" \ --trusted-host=pypi.python.org \ --trusted-host=pypi.org \ --trusted-host=files.pythonhosted.org
Alternative Solutions to the SSL Certificate Verify Failed Error in Python
If you have reached this part of the article, you might be looking for more solutions to help you with the SSL certificate error. And thankfully, we have brought you a few more answers to help you fix the certificate error.
The possible solutions are the below:
- Use the correct and updated time and date configurations to synchronize with Google’s time.
- Use HTTP instead of HTTPS e.g. (–index-url=http://pypi.python.org/simple/).
- Use(–cert <trusted.pem>) or CA_BUNDLE variable to specify the alternative CA bundle.
- Import SSL and “print(ssl.get_default_verify_paths()) to validate the current one exist.
- OpenSSL has a pair of environments (SSL_CERT_DIR, SSL_CERT_FILE) that specify different certificate databases according to PEP-476.
- Use –trusted-host accordingly to mark the host as trusted.
- Make sure to use verify=False for the request.get command.
- Use –proxy<proxy> to avoid certificate checks.
