TPM 2.0 TSS Bindings for Python
Reason this release was yanked:
Outdated and broken, use master
Project description
tpm2-pytss
TPM2 TSS Python bindings for Enhanced System API (ESYS).
Supported versions of Python are
- 3.5
- 3.6
- 3.7
- 3.8
Features
We support the FAPI, ESAPI, and marshalling library.
Dependencies
This has been tested against TPM2 TSS 2.4.0, SWIG 3 and SWIG 4.
tpm2-tss
You need to install tpm2-tss prior to installing this, INSTALL.md.
pkg-config
You need to install pkg-config
swig
You need to install swig
Ubuntu
$ sudo apt-get -y install swig pkg-config
ldconfig
When you ran ./configure for tpm2-tss if you didn't supply a prefix it usually
defaults to /usr/local/. When you ran make install it then installed the
libraries under that path. Your pacakge manager usually installs libraries to
/usr. If you properly configure the ldconfig tool, it'll make the libraries
you just installed available from within /usr/local (which means they won't
clash with things your package manager installs). If you don't configure it then
you might get this error:
ImportError: libtss2-esys.so.0: cannot open shared object file: No such file or directory
We make a config file that tells ldconfig to look in /usr/local/lib for
shared libraries, then we run ldconfig.
$ sudo mkdir -p /etc/ld.so.conf.d/
$ echo 'include /etc/ld.so.conf.d/*.conf' | sudo tee -a /etc/ld.so.conf
$ echo '/usr/local/lib' | sudo tee -a /etc/ld.so.conf.d/libc.conf
$ sudo ldconfig

Install
Install from PyPi.
$ python3 -m pip install tpm2-pytss
Or install from the Git repo
$ git clone --depth 1 --recurse-submodules -b ${TPM2_PYTSS_VERSION} \
https://github.com/tpm2-software/tpm2-pytss
$ cd tpm2-pytss
$ python3 -m pip install -e .
Examples
See tests/ folder for example usage.
Testing
You need to have tpm_server installed in your path to run the tests.
Download the latest version from https://sourceforge.net/projects/ibmswtpm2/files/
and put it somewher in your $PATH.
$ python3 setup.py test
Logging
To get traces of all calls into the TSS, use the TPM2_PYTSS_LOG_LEVEL
environment variable.
$ export TPM2_PYTSS_LOG_LEVEL=debug
