SSL Certificates and Profiles

Creating and Importing Certs and Key

You want the highest levels of encryption between the BIG-IP and the client, but you do not require the same levels of encryption between the BIG-IP and the server and you would like to save server processing power. You are going to create new SSL certificates with 2048 bit keys for client-side SSL and import a certificate you own that has a 1024 bit keys for the server-side SSL processing.

Create the client-side SSL certificate and key.

Go to System >> File Management >> SSL Certificate List and select Create and enter the following information.

Name	new_ssl_cert
Issuer	Self
Common Name	ltm301a.f5demo.com
Division	Training
Organization	F5
Locality	Lab
Country	United States
State	Washington
Email	example@f5demo.com
Subject Alternative Name	<leave this blank>

By default, a self-sign certificate starts with a Lifetime of 365 days and the key type is 2048 bit RSA.

Import the SSL certificate and key below to the BIG-IP to be used for server-side encryption by selecting Import.

You can find the cert and key under the Lab Guides link on your browser bookmark bar. Look for the Cert 301a LTM Architect.txt file/link. Open the link and the certificate and key are in there under LAB 5 - SSL

You may want to import the Key first, as it will validate certificate if your naming both the same. If you were to import the certificate first and then import a Key with the same name you could technically attached an invalid key to the certificate.

Import the Key (Type), named import_ssl_cert, leave the Password blank.

Q1. What is the common name of your imported certificate and when does it expire?

SSL Profile and Virtual Servers

Now you will create a custom client and server side SSL profiles using your new certificates and key and attach them to you secure_vs and test.

Create a custom client SSL profile using your new_ssl_cert certificate, by going to Profiles > SSL > Client.

Name you new profile my-client-ssl and place new_ssl_cert in the Certificate and Key drop-downs.

Make sure you Add the certificate and key before you Finish.

Go to the SSL Server profiles and create a new profile named my-server-ssl with your import-ssl-cert certificate and key.

Replace the current default client-side and server-side SSL profiles with your new SSL profiles.

Browse to http://10.1.10.115.
