%description
The tpm2-0-tss package provides a TPM 2.0 TSS implementation. This
implementation is developed by INTEL. This package contains the libraries,
see the tpm2.0-abrmd package for the resource manager daemon, tpm2.0-tools for
utilities.

%package -n libtss2-esys0
Summary:        TPM2 Enhanced System API (ESAPI)
Group:          System/Libraries

%description -n libtss2-esys0
This API is a 1-to-1 mapping of the TPM2 commands documented in Part 3 of the
TPM2 specification. Additionally there are asynchronous versions of each
command. In addition to SAPI, the ESAPI performs tracking of meta data for
TPM object and automatic calculation of session based authorization and
encryption values. Both the synchronous and asynchronous API are exposed
through this library.

%package -n libtss2-sys0
Summary:        TPM2 System API (SAPI)
Group:          System/Libraries

%description -n libtss2-sys0
System API (SAPI) as described in the system level API and TPM command
transmission interface specification. This API is a 1-to-1 mapping of the TPM2
commands documented in Part 3 of the TPM2 specification. Additionally there
are asynchronous versions of each command. These asynchronous variants may be
useful for integration into event-driven programming environments. Both the
synchronous and asynchronous API are exposed through this library.

%package -n libtss2-mu0
Summary:        TPM2 marshaling/unmarshaling library
Group:          System/Libraries

%description -n libtss2-mu0
Marshaling/Unmarshaling (MU) as described in the TCG TSS 2.0
Marshaling/Unmarshaling API Specification. This API provides a set of
marshaling and unmarshaling functions for all data types defined by the TPM
library specification.

%package -n libtss2-tcti-device0
Summary:        TCTI interface library for using a native TPM device node
Group:          System/Libraries

%description -n libtss2-tcti-device0
TPM Command Transmission Interface library for communicating with a
TPM device node. This provides direct access to the TPM through the Linux
kernel driver.

%package -n libtss2-tcti-mssim0
Summary:        TCTI interface library for Microsoft software TPM2 simulator
Group:          System/Libraries

%description -n libtss2-tcti-mssim0
TPM Command Transmission Interface library for communicating using the
protocol exposed by the Microsoft software TPM2 simulator.

# the same user is employed by trousers (and was employed by the old
# resourcemgr shipped with the tpm2-0-tss package):
#
# trousers just needs those accounts for dropping privileges to. The service
# starts as root and uses set*id to drop to tss, after the tpm device has been
# opened.
#
# tpm2-abrmd has no set*id handling and thus requires /dev/tpm to be owned
# by the tss user. Therefore we also need to install a udev rule file.
#
# trousers was here first and created the user like this, also giving it a
# home in /var/lib/tpm. I don't think the home directory is used by any of
# both packages ATM. Trousers is keeping state there, but the directory is
# owned by root and files are opened before dropping privileges. The passwd
# entry seems not to be evaluated.
#
# so I guess we can share the account between the two packages for now.
