XYGATE: "XTR Error: SSL: InitializeSecurityContext error: Illegal message"

This error happens when the windows client running the XYGATE GUI and NonStop do not have a common cipher suite enabled.

A cipher suite that is enabled in the TRCONF file must also be enabled on the client to connect the GUI successfully to the NonStop. (Example TRCONF entry below)


For reference when checking the windows client here are the Cipher Suites supported as of XYGATE 2.27 with their corresponding cipher numbers:

TLS_RSA_WITH_3DES_EDE_CBC_SHA   (10)
TLS_RSA_WITH_AES_128_CBC_SHA    (47)
TLS_RSA_WITH_AES_256_CBC_SHA    (53)
TLS_RSA_WITH_AES_128_CBC_SHA256 (60)
TLS_RSA_WITH_AES_256_CBC_SHA256 (61)
