DTLS v1.0 supports 5 of the cipher suites and DTLS v1.2 supports 10 of the cipher suites.FIPS/NIST(SP800-52) compliance mode: Session launch is not supported in the scenarios when Cipher set is configured as COM on the server with any of the cipher sets(COM/GOV/ANY) on the client and vice-versa due to lack of common cipher suites.OPEN mode: Session launch not supported when Client configures cipher set to GOV and VDA has cipher set configured to COM (due to lack of common cipher suite).* SCSV is a renagotiation indication ciphersuite per RFC5746Įxpected failure scenarios and corner cases In the case you disable deprecated cipher suites, make sure to avoid the following failure scenarios: SP800-52 mode always implies FIPS crypto.Ģ) Ciphersuite disabled by default.Must be enabled withģ) Ciphersuite not available for DTLS protocol Please find below the cipher matrix for a deeper understanding of the ciphers supported by the latest SSL SDK. To enable or disable DTLS, you can configure the HDX Adaptive Transport policy on the DDC.Similarly, to enable RC4-128-SHA cipher suite, both flags 1 and 3 should be enabled. This means, if it is intended to enable RC4-128-MD5 cipher suite, both flags 1 and 2 should be enabled.Although RC4-128-MD5 (flag 2) and RC4-128-SHA (flag 3) are subsets of TLS_RSA_, additional flags are given for the two ciphers.Enabling TLS_RSA_ flag (flag 1) alone enables 6 cipher suites.Use the toggle options to Enable/Disable the ciphers.Under the Computer Configuration node, go to Administrative Template > Citrix Component > Citrix Receiver > Network Routing > Deprecated Cipher Suites.Open the Citrix Receiver GPO administrative template by running gpedit.msc.In case of an upgrade, the existing settings are retained when the latest files are imported. Refer to the Product Documentation for detailed instructions. Add the Receiver GPO template if it is not added to the local GPO.Steps to Disable/Re-Enable Deprecated Ciphers Note that these are enabled by default on the GPO in Receiver for Windows (4.12).
