Is TLS 1.2, 1.1 Supported on Web Interface 5.4?

Question:
Web Interface 5.4 ??-- - ??Is TLS 1.2, 1.1 supported

Answer:
No it's not.??Upgrade to StoreFront 3.x.
On page 173 of the product documentation guide for Web Interface 5.4 you will find the following paragraph:??

"??Transport Layer Security -??
Transport Layer Security (TLS) is the latest, standardized version of the SSL protocol. The??
Internet Engineering Taskforce (IETF) renamed it TLS when they took over responsibility for??
the development of SSL as an open standard. Like SSL, TLS provides server authentication,??
encryption of the data stream, and message integrity checks.??
Support for TLS Version 1.0 is included in all supported versions of XenApp for Windows and??
XenDesktop. Because there are only minor technical differences between SSL Version 3.0??
and TLS Version 1.0, the server certificates you use for SSL in your installation also work??
with TLS.??
Some organizations, including U.S. government organizations, require the use of TLS to??
secure data communications. These organizations may also require the use of validated??
cryptography, such as Federal Information Processing Standard (FIPS) 140. FIPS is a standard??
for cryptography.??
Note: The maximum SSL/TLS certificate key size supported by the Web Interface for Java??
Application Servers is 2048 bits."

Here TLS 1.2 or 1.1 is nowhere mentioned, hence upgrade is highly recommended.
Also since WI 5.4 was designed in C# and support for C# has ended by Microsoft nearly two years ago any enhancement request will not be possible.
