One of the most widely used features of our load balancer is the ability to offload SSL traffic by terminating HTTPS connections on the balancer itself. This has a variety of benefits including; centralized certificate management, offloading CPU intensive decryption/encryption tasks from your web servers and enabling the balancer to make complex layer-7 routing decisions on encrypted workloads.
What is a PEM?
The balancer requires the certificates be in the .pem format. A PEM is essentially just the certificate, key, as well as any intermediate certificates (if required) all combined into a single file.
You can simply combine all of these into a single file with the extension .pem.
Creating your PEM file
It should look like this:
-----BEGIN RSA PRIVATE KEY----- (REQUIRED: Your Private Key: website.key) -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- (REQUIRED: Your Primary SSL certificate: website.crt) -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- (OPTIONALLY: Your Intermediate certificate: NetworkSolutions_CA.crt) -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- (OPTIONALLY: Your Root certificate: TrustedRoot.crt) -----END CERTIFICATE-----
Remember you must remove the passphrase from your .key file before adding it to the PEM!
