Therefore, session launch is not supported from a client configured for GOV to a VDA configured for COM.DTLS v1.2 supports the following cipher suites:.DTLS v1.0 supports the following cipher suites:.This happens because a common cipher suite is absent. FIPS/NIST(SP800-52) compliance mode : Session launch is not supported when the VDA is configured for COM the client for COM, GOV, or ANY, or the other way around.OPEN mode : Session launch is not supported when the client is configured for GOV and the VDA for COM. The following cipher matrix provides the ciphers supported by the latest SSL SDK:Įxpected failure scenarios and edge cases In earlier releases, the GPO configuration that was available under the below Computer Configuration node which allowed to enable the deprecated cipher suites has been removed now.Īdministrative Template > Citrix Component > Citrix Workspace > Network Routing > Deprecated Cipher Suites The following advanced cipher suites are supported:

This document aims to detail the changes to the cipher suites.

If your environment is not configured with the TLS_ECDHE_RSA_ cipher suites, client launches are not supported due to weak ciphers. Instead, this release supports the advanced TLS_ECDHE_RSA_ cipher suites. In this release, the TLS_RSA_ cipher suites have been removed entirely.

These cipher suites were deprecated in Citrix Receiver version 13.10 with an option for backward compatibility. Cipher suites with the prefix TLS_RSA_ do not offer forward secrecy and are considered weak. Objective This feature is an important change to the secure communication protocol. If the configurations on the backend is not updated to support one of the 3 supported strong cipher suites, you will not be able to connect. Note: Citrix has deprecated weak cryptography across the board. Also for Citrix Workspace App 1910 and later. Applicable Products Citrix Workspace App 1904 for Windows and later.
