To remove the OpenSSL cryptographic library from Tectia Server on Windows, first disable FIPS mode, if it has been enabled, using the Configuration GUI.


If both Tectia Client and Tectia Server are installed, ensure that user-specific Connection Broker configuration(s) have FIPS mode disabled and that the system wide Tectia FIPSMODE switch file is removed. The FIPSMODE file is automatically removed when FIPS mode is disabled from the Tectia Server Configuration GUI (for more information, see Cryptographic library and crypto-lib ).
