Error: error:0308010c:digital envelope routines::unsupported

Must read

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are widely used cryptographic protocols for securing communication over the internet. SSL/TLS certificates are used to verify the identity of a server or website and to establish a secure connection between the client and the server.

However, sometimes when attempting to establish a secure connection, an error message “error:0308010c:digital envelope routines::unsupported” may be encountered. This error message is indicative of an issue with the cryptographic algorithm used for the SSL/TLS certificate. In this article, we will explore the causes of this error, how to troubleshoot it, and steps you can take to prevent encountering it in the future.

What is the Error?

The error message “error:0308010c:digital envelope routines::unsupported” is a common error encountered when there is an issue with the SSL/TLS certificate that is being used for encryption. This error message is typically seen in the context of SSL/TLS encrypted connections, such as when attempting to establish a secure connection to a website or server.

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols used for secure communication over the internet. SSL/TLS certificates are used to verify the identity of a server or website and to establish a secure connection between the client (such as a web browser) and the server.

Why it occurs?

The error message “error:0308010c:digital envelope routines::unsupported” occurs when there is an issue with the cryptographic algorithm used for the SSL/TLS certificate. Specifically, this error message indicates that the cryptographic algorithm used for the SSL/TLS certificate is not supported by the version of OpenSSL that is being used.

OpenSSL is an open-source software library that provides cryptographic functions and tools for secure communication. It is widely used in many applications and services that require encryption, including web servers, email servers, and VPNs.

When attempting to establish a secure connection, the client and server negotiate which cryptographic algorithms to use for encryption. If the server is configured to use a cryptographic algorithm that is not supported by the version of OpenSSL being used by the client, the client will receive the “error:0308010c:digital envelope routines::unsupported” error message.

How to troubleshoot it?

If you encounter the “error:0308010c:digital envelope routines::unsupported” error message, there are several steps you can take to troubleshoot the issue:

  1. Check the SSL/TLS certificate: Verify that the SSL/TLS certificate being used by the server is valid and has not expired. You can do this by examining the certificate details in your web browser or using a command-line tool like OpenSSL.
  2. Check the version of OpenSSL: Verify that the version of OpenSSL being used by the client is up to date and supports the cryptographic algorithm used by the SSL/TLS certificate. You can check the version of OpenSSL by running the command “openssl version” in a terminal or command prompt.
  3. Update OpenSSL: If the version of OpenSSL being used by the client is not up to date or does not support the cryptographic algorithm used by the SSL/TLS certificate, you may need to update OpenSSL to a newer version.
  4. Obtain a new SSL/TLS certificate: If the cryptographic algorithm used by the SSL/TLS certificate is not supported by the version of OpenSSL being used by the client, you may need to obtain a new SSL/TLS certificate that uses a supported cryptographic algorithm.
  5. Check the server configuration: Verify that the server is configured to use a supported cryptographic algorithm and that the SSL/TLS certificate is configured correctly. You may need to consult with the server administrator or service provider to troubleshoot server configuration issues.

How to prevent it?

To prevent encountering the “error:0308010c:digital envelope routines::unsupported” error message, there are several steps you can take:

  1. Keep OpenSSL up to date: Ensure that the version of OpenSSL being used by the client is up to date and includes support for the cryptographic algorithms used by SSL/TLS certificates.
  2. Use trusted SSL/TLS certificates: Only use SSL/TLS certificates from trusted certificate authorities. This will help ensure that the cryptographic algorithm used by the SSL/TLS certificate is supported by the version of OpenSSL being used by the client.
  3. Monitor SSL/TLS certificate expiration: Monitor the expiration date of SSL/TLS certificates and renew them before they expire. Expired SSL/TLS certificates can cause issues with secure connections

Conclusion:

In conclusion, the “error:0308010c:digital envelope routines::unsupported” error message can be a frustrating obstacle when attempting to establish secure connections over the internet. However, by following the troubleshooting steps outlined in this article and taking preventative measures, such as keeping OpenSSL up to date and using trusted SSL/TLS certificates, you can avoid encountering this error message and ensure that your communication over the internet remains secure. By being proactive and vigilant in maintaining secure connections, you can protect your data and privacy online.
