Error:0308010c:digital envelope routines::unsupported. OpenSSL is a widely-used cryptographic library that is freely available to the public. You may get the “0308010c:digital envelope routines::unsupported” issue while using OpenSSL. The significance of this fallacy, along with its root causes and potential remedies, will be discussed in this article.
What is the “0308010c:digital envelope routines::unsupported” Error?
An unsupported encryption technique is denoted by the “0308010c:digital envelope routines::unsupported” OpenSSL error code. When OpenSSL encounters a digital certificate or key file for which it does not understand the encryption algorithm, this error occurs. Another common cause of this problem is employing an encryption technique that is incompatible with the version of OpenSSL you are running.
Causes of the “0308010c:digital envelope routines::unsupported” Error:
The “0308010c:digital envelope routines::unsupported” OpenSSL issue could occur for a number of different reasons. For example:
Unsupported Encryption Algorithm
This error message appears if OpenSSL is unable to decrypt the digital certificate or key file because it employs an unsupported encryption algorithm.
Check the Encryption Algorithm
The digital certificate or key file must utilize an encryption technique that is supported by OpenSSL. For this, either consult the official OpenSSL documentation or get in touch with the digital certificate’s issuing authority.
Verify the Certificate or Key File
Make sure the digital certificate or key file is legitimate and not damaged in any way. The certificate or key file can be validated by using an online certificate checker or OpenSSL instructions.
Use a Different Encryption Algorithm
If OpenSSL doesn’t support the encryption algorithm used by the digital certificate or key file, you’ll need to switch to one that does.
Conclusion
Error:0308010c:digital envelope routines::unsupported encryption methods, out-of-date OpenSSL installations, and damaged certificate or key files are all potential reasons for the “0308010c:digital envelope routines::unsupported” issue in OpenSSL. If you’re having trouble utilizing OpenSSL to communicate securely over the internet, this article should help you fix the problem.
