Configure Advanced TLS/SSL Options
You can select the security protocols and cryptographic algorithms that are used to encrypt
communications between Horizon Client and Horizon servers and between Horizon Client and the agent
in the remote desktop.
By default, TLSv1.0, TLSv1.1, and TLSv1.2 are enabled. SSL v2.0 and 3.0 are not supported. The default
cipher control string is "!aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH
+AES:ECDH+AES:RSA+AES".
If you configure a security protocol for Horizon Client that is not enabled on the Horizon server to which
the client connects, a TLS/SSL error occurs and the connection fails.
For information about configuring the security protocols that are accepted by Connection Server
instances, see the View Security document.
Procedure
1 Tap Settings at the bottom of the Horizon Client window.
2 Tap Advanced SSL Options.
3 Make sure that the Reset to Default Settings option is set to off.
4 To enable or disable a security protocol, tap the On or Off toggle next to the security protocol name.
5 To change the cipher control string, replace the default string.
6 (Optional) If you need to revert to the default settings, tap Reset in the upper right corner of the
window.
Your changes take effect the next time you connect to the server.
Configure VMware Blast Options
You can configure H.264 decoding and network condition options for remote desktop and application
sessions that use the VMware Blast display protocol.
You can configure H.264 decoding before or after you connect to a server.
You can change the network condition to any type before you connect to a server. After you connect to a
server, you can switch the network condition between Typical and Excellent (you cannot select Poor), but
only if Typical or Excellent was selected before you connected to the server. You cannot change the
network condition after you connect to a server if Poor was selected before you connected.
After you connect to a server, the VMware Blast setting is visible only if VMware Blast is the preferred
protocol.
Prerequisites
To use this feature, Horizon Agent 7.0 or later must be installed.
