The .NET SDK contains the OpenSSL library but no longer contains the axTLS library. The OpenSSL library provides the APIs necessary to use the FIPS module If you require FIPS mode for communications, make sure that you download the bundle that has "fips" in the name of the file. If you have this version, FIPS is automatically used for communication. No special configuration for FIPS support is needed.Extract the bundle, and check that you have the content you require.
The SDK bundle includes three main directories, Doc, Example, and SDK. The contents of these directories are shown in the following table:
