Introduction

OpenSSL errors are some of the common issues Python users face when making web requests using the Requests module. OpenSSL is a toolkit implementing Secure Sockets Layer and Transport Layer Security protocols. It offers cryptographic functions that facilitate secure communication between web applications. However, poor handling of OpenSSL can significantly impact your application’s performance and compromise its security.

The purpose of this article

This article discusses the most common OpenSSL errors encountered when using Python Requests. It further presents a comparison table highlighting the causes and solutions to each error. We also provide our opinion on what we believe is the best way to approach these errors.

Error: SSL: CERTIFICATE_VERIFY_FAILED

This error occurs when the server you are trying to connect to has an untrusted or expired SSL certificate. Python Requests will not trust the certificate by default.

Cause

The certificate provided by the server does not meet the trust criterion required by the requesting client. Python Requests expects a trusted certificate by an established trusted authority.

Solution

You will need to trust the server’s SSL certificateon the client-side to resolve this issue. You can achieve this by telling Requests to ignore SSL verification. However, we don’t recommend this solution as it can pose security risks. Alternatively, you can try installing the SSL certificate on your local system and configure your Requests object to use that certificate as trusted.

Error: SSL: Wrong Version Number

This error occurs when your Python Requests module uses an outdated SSL version that’s incompatible with the server.

Cause

The server may be using a newer version of SSL that the client cannot handle. This is usually because the client doesn’t have supported TLS/SSL versions configured correctly.

Solution

You can resolve this by updating your OpenSSL libraries and ensuring that your Requests module supports the new version of SSL. You may also need to configure your client Requests object to use the correct TLS/SSL versions.

Error: SSL: UNSUPPORTED_PROTOCOL

This error occurs when your client Requests module uses an SSL protocol that the server does not support.

Cause

The server is not designed to handle TLS/SSL versions used by the client. This can occur when a client system has disabled SSLv2, but the server still uses it.

Solution

You will need to configure the server to accept the SSL protocol used by the client or use an SSL protocol that the server supports. In addition, you may need to update your Python and Requests version to the latest release.

Error: SSL: SSLV3_ALERT_HANDSHAKE_FAILURE

This error occurs when there is a problem with the SSL handshake process between the client and the server.

Cause

A mismatch between SSL versions or problems with the SSL certificate presented by the server can cause this error.

Solution

You can resolve this error by matching the SSL/TLS protocol versions of the server and client. Use an SSL certificate and private key file that are compatible with each other. Also, consider using another DNS resolver or ping various resolvers to confirm that your DNS is resolving addresses.

The comparison table

Errors Causes Solutions
SSL: CERTIFICATE_VERIFY_FAILED The server has an untrusted or expired SSL certificate. Trust the SSL certificate or configure the Requests object to use an SSL certificate.
SSL: Wrong Version Number The server uses an SSL version incompatible with the client’s Requests module. Update your OpenSSL library and configure your Requests module to support the new SSL version.
SSL: UNSUPPORTED_PROTOCOL The server doesn’t support the provided SSL protocol used by the client. Configure the server to accept the SSL protocol implemented by the client or use an SSL protocol that the server supports.
SSL: SSLV3_ALERT_HANDSHAKE_FAILURE Problems with the SSL handshake process. Match the SSL/TLS versions of the server and client, use a compatible SSL certificate and private key file, and verify the DNS resolver.

Our opinion

When handling OpenSSL errors with Requests, it is always essential to prioritize security. It’s not recommended to ignore SSL verification or SSL errors for a production environment. Instead, it is best practice to trust reliable certificate authorities and test your TLS/SSL configurations regularly.

Conclusion

In conclusion, most of the errors discussed in this article have similar solutions: update libraries and Request modules, enable SSL verification updates, and correctly configure SSL/TLS protocols in the Requests module. By following these recommendations, you can mitigate most common OpenSSL errors and ensure that your web application is secure.

Thank you for reading this article about common OpenSSL errors when using Python Requests. We hope that it has been informative and helpful in resolving any issues you may have encountered.

It is important to keep in mind that OpenSSL errors can be caused by a variety of factors, such as incorrect SSL certificates or outdated OpenSSL versions. If you continue to encounter these errors, we recommend checking for updates and verifying that all SSL certificates are properly configured.

If you have any further questions or concerns, please do not hesitate to reach out to the Python community or seek assistance from a trusted developer. We wish you the best of luck in your coding endeavors!

People Also Ask About Common OpenSSL Errors When Using Python Requests:

  1. What is OpenSSL error?

    • An OpenSSL error is an error that occurs when OpenSSL, a widely-used software library for secure communication, encounters an issue with the SSL/TLS protocol. These errors may occur due to incorrect configuration, outdated versions, or compatibility issues.
  2. Why am I getting OpenSSL errors when using Python Requests?

    • If you are using Python Requests library to interact with SSL/TLS secured web servers, you may encounter OpenSSL errors due to various reasons like outdated OpenSSL version, incorrect SSL certificate, or misconfigured SSL settings.
  3. What are some common OpenSSL errors that occur when using Python Requests?

    • Some of the common OpenSSL errors that may occur while using Python Requests include ‘SSL23_GET_SERVER_HELLO:unknown protocol’, ‘certificate verify failed’, ‘tlsv1 alert protocol version’, and ‘SSL routines:ssl3_get_record:wrong version number’.
  4. How can I fix OpenSSL errors when using Python Requests?

    • There are several ways to fix OpenSSL errors when using Python Requests, including upgrading OpenSSL to the latest version, verifying SSL certificates, and configuring SSL settings correctly. Additionally, you can try disabling SSL verification temporarily by passing the ‘verify=False’ parameter to the Requests method.
  5. What should I do if I still encounter OpenSSL errors after trying these solutions?

    • If you still encounter OpenSSL errors after trying these solutions, you may need to consult the documentation for the web server you are trying to connect to, or seek assistance from a developer or system administrator with experience in SSL/TLS protocols and Python Requests library.
