# Determining the OpenSSL version

> Learn how to check\_which OpenSSL version is installed. Verify if specific features are available or if the version may be affected by a security issue.

This article describes how to check which OpenSSL version is installed on a server. You may need to do this to verify whether or not a particular feature is available, or check if the installed version is affected by a security issue.

To check which OpenSSL version is installed on a Linux server, log in to your account [using SSH](/docs/using-ssh-secure-shell), and then type the following command at the command line:

```bash theme={null}
openssl version
```

This command tells you which OpenSSL version is installed on your server.
