This directory contains the CSharp wrapper for the TPM 2.0 API wrapper API.
Once you have created the simulator, you can build wolfssl as described in the
README.md in the root of this repo. Then you can build wolfTPM:
A Visual Studio solution is provided. This will allow you to build the
wrappers. In order to run the tests you will need to update the
.runsettings to add the location of the wolftpm.dll. There is a
placeholder to leverage a vcpkg build, but cmake can also be used to
build wolfTPM with Visual Studios.
When building wolfTPM with cmake on Windows here is an example of the settings used:
"WOLFTPM_INTERFACE": "WINAPI",
"WOLFTPM_EXAMPLES": "no",
"WOLFTPM_DEBUG": "yes",
"WITH_WOLFSSL": "C:/Users/[username]/wolfssl/out/install/windows-default"
The wrapper has been tested with the swtpm TCP protocol for use with
the simulator. Please follow instructions in the docs/SWTPM.md file
for building and running the simulator.
./autogen.sh
./configure --enable-swtpm
make all
make check
Prerequisites for linux
apt install mono-tools-devel nunit nunit-console
You can then build wolfTPM as described above in the Linux or Windows section of this document. After that, build and run the wolfTPM CSharp wrapper and run some tests:
cd wrapper/CSharp
mcs wolfTPM.cs wolfTPM-tests.cs -r:/usr/lib/cli/nunit.framework-2.6.3/nunit.framework.dll -t:library
# run selftest case
LD_LIBRARY_PATH=../../src/.libs/ nunit-console wolfTPM.dll -run=tpm_csharp_test.WolfTPMTest.TrySelfTest
#run all tests
LD_LIBRARY_PATH=../../src/.libs/ nunit-console wolfTPM.dll
You should see something similar to the following output:
Selected test(s): tpm_csharp_test.WolfTPMTest.TrySelfTest
wolfSSL Entering wolfCrypt_Init
