What is a cipher suite?
A cipher suite is a set of algorithms that helps secure a network connection using protocols like SSL and TLS. When your browser connects to a secure website (one that uses HTTPS), the browser and the server need to agree on a cipher suite to use. This suite determines how they will:
- Authenticate each other (confirm identities)
- Exchange keys securely
- Encrypt the data being sent
- Ensure data integrity (verify that data hasn't been altered)
Potential error messages if using an outdated browser
While we cannot predict the exact message each customer will see (with many variables, such as browser version, connection, etc.), you will likely see an SSL Error or TLS Error in your browser's error code.
Examples of errors you may encounter
Google Chrome
Secure Connection Failed
An error occurred during a connection to *Intralinks.com. Cannot communicate securely with peer: no common encryption algorithm(s).
Error code: SSL_ERROR_NO_CIPHER_OVERLAP
Firefox
Your connection is not private
Attackers might be trying to steal your information (for example, passwords, messages, or credit cards).
NET::ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Recommended actions
- Ensure that you are using the latest version of a supported browser. We recommend:
- Google Chrome
- Mozilla Firefox
- Microsoft Edge
- Safari
- Verify system date and time: An incorrect system clock can cause SSL/TLS errors. Use https://time.is/ to check the accuracy of your system's date/time settings.
- IT Support / alternative device: If updating your browser isn't feasible, consider contacting your internal IT team for further assistance and/or accessing Intralinks from a different device.
- Ensure that your application and operating system support TLS 1.2 and above.
- Contact Intralinks Support: If your access issues to our service persist, our Support team can help. Click the Get Help button on the lower right and enter support agent.
