SSL Certificates Template

By supporting the use of SSL certificates and keys, Silver Peak provides deduplication for Secure Socket Layer (SSL) encrypted WAN traffic

n	Silver Peak decrypts SSL data using the configured certificates and keys, optimizes the data, and transmits data over an IPSec tunnel. The peer Silver Peak appliance uses configured SSL certificates to re-encrypt data before transmitting.

n	Peers that exchange and optimize SSL traffic must use the same certificate and key.

n	Use this template to provision a certificate and its associated key across multiple appliances.

•	You can add either a PFX certificate (generally, for Microsoft servers) or a PEM certificate.

•	The default is PEM when PFX Certificate File is deselected.

•	If the key file has an encrypted key, enter the passphrase needed to decrypt it.

n	Silver Peak supports

•	X509 Privacy Enhanced Mail (PEM), Personal Information Exchange (PFX), and RSA key 1024-bit and 2048-bit certificate formats.

•	SAN (Subject Alternative Name) certificates. SAN certificates enable sharing of a single certificate across multiple servers and services.

n	Silver Peak appliances support:

•	Protocol versions: SSLv3, SSLv3.3, TLS1.0, TLS1.1, TLS1.2

•	Key exchanges: RSA, DHE, ECDHE

•	Authentication: RSA

•	Cipher algorithms: RC4, 3DES, AES128, AES256, AES128-GCM, AES256-GCM

•	Message Digests: MD5, SHA, SHA256, SHA284

n	Before installing the certificates, you must do the following:

•	Configure the tunnels bilaterally for IPSec mode. To do so, access the Tunnels template and for Mode, select ipsec.

•	Verify that TCP acceleration and SSL acceleration are enabled. To do so, access the Configuration > Optimization Policies page, and review the Set Actions.

n	If you choose to be able to decrypt the flow, optimize it, and send it in the clear between appliances, then access the System template and select SSL optimization for non-IPsec tunnels.
