I will use one of our labs from to demonstrate how to configure and test decryption using the premaster key. I will not dive into the intricacies of why this can be used to decrypt data because that part of cryptology is an entirely separate topic. Wireshark provides another means for decrypting data as well by using the pre-master secret. Normally, the easiest way to decrypt data is to use the private key for the corresponding public key. This is especially true with FIPs NetScaler applianes. When the application data is encrypted however, troubleshooting application data becomes more of a challenge. There are many times when IT admins need to utilize a packet inspection such as Wireshark.

The purpose of the blog is to provide a guide on how to decrypt SSL/TLS traffic without a private key. Citrix App Delivery and Security Service.
