BIGIP Cookie Decoder

Decode BIGIP Cookie
What is BIGIP Cookie Decoder?
The 'BIGIP Cookie Decoder' is a Chrome extension that decodes the encoded cookies used by the F5 BIG-IP load balancer. These cookies, which are automatically sent in every client request, allow load balancing control by tracking each client’s server association. The extension reverse-engineers the F5 algorithm used to encode this data, revealing the IP address and TCP port of the host managing the connection. Its primary use is aiding administrators in troubleshooting scenarios. However, it's important to note that the extension is unable to handle non-encrypted cookies due to their security risk.

Extension summary

The F5 BIG-IP load balancer uses an encoded cookie to maintain stateful connections from the client to the server. These cookies are automatically sent in every request to the domain that set them. This allows a simple way to track each client’s server association for load balancing control.

This extension reverse the F5 algorithm used to encode the data, and exposes the IP address and TCP port of the host that is actually handling your connection.

It was made to help administrators in trobleshooting situations.

Note that non encrypted cookies are considered a security issue, and this extension will not work if your load balancer was configured to use the non reversible crypto.
