About SSL and Secure Inner Channels : Prerequisite tasks
  
Prerequisite tasks
Complete these prerequisite tasks before you begin SSL configuration:
1. Connect to the Management Console using HTTPS to protect your SSL private keys and certificates.
2. On the client-side appliance and server-side SteelHead, make sure you have a valid Enhanced Cryptography License Key. If you do not have a valid Enhanced Cryptography License Key file, go to https://sslcert.riverbed.com and follow the procedures documented there.
The SSL License is called the Enhanced Cryptographic License Key, because it also activates RiOS data store encryption and creates secure channels while optimizing encrypted MAPI and SMB-signed traffic (even if the appliances are not configured for optimizing SSL traffic).
3. Back up your private keys and the CA-signed certificates before you begin the SSL configuration process.
