In terms of calling the tss from java you might then want to look at tpm2-swig
for bindings: https://github.com/tpm2-software/tpm2-swig

Cheers,
Andreas

Hi Phani,

after a quick research, I have found the following: https://android.googlesource.com/platform/external/tpm2-tss/
I would be curious to get to know if that fits to your request.

Best,
Florian

Hello All,

We are trying to use  TPM2.0 on Android, would like to port TPM2 TSS on to it,
could any of you suggest any tutorials on the NDK Build compilation of TPM2 TSS and relevant details to use TPM2 TSS on Android

Regards
Phani Srinivas S

But I guess all my ramblings about NDK builds are pointless, because unless something has changed,
You won't have access to the TPM chip anyways from applications.

[tpm2] Re: TPM2 TSS on Android

[Roberts, William C]

There are some other things to be aware of here. The first being that Android-NDK has pretty clean
And documented integration now with autoconf projects, so it's pretty simple to build the:
  - tss2-sys
  - tss2-tcti-*
  - tss2-tctildr
  - tss2-mu
  - tss2-rc

Libraries by following the section on autoconf:
https://developer.android.com/ndk/guides/other_build_systems#autoconf

Then configuring the project like so:
./configure --host=$TARGET --disable-esys --disable-fapi

make -j$(nproc)
<snip>
  CCLD     libutil.la
  CCLD     src/tss2-mu/libtss2-mu.la
  CCLD     src/tss2-tcti/libtss2-tctildr.la
  CCLD     src/tss2-rc/libtss2-rc.la
  CCLD     src/tss2-tcti/libtss2-tcti-device.la
  CCLD     src/tss2-tcti/libtss2-tcti-swtpm.la
  CCLD     src/tss2-tcti/libtss2-tcti-pcap.la
  CCLD     src/tss2-tcti/libtss2-tcti-mssim.la
  CCLD     src/tss2-tcti/libtss2-tcti-cmd.la
  CCLD     src/tss2-sys/libtss2-sys.la

readelf -h ./src/tss2-sys/.libs/libtss2-sys.so | grep -i Machine
  Machine:                           AArch64

You can download the NDK from here:
https://developer.android.com/ndk/downloads

It get's tricky in that in order to use the ESYS or FAPI libraries, you need to satisfy the openssl dependency.
For Android in-tree, they have Boring OSSL and are carrying patches on our project for integrating with
Boring SSL.

For mainline, you can build OSSL against the NDK and then configure tpm2-tss project using normal
autoconf idioms to use that OSSL:
https://wiki.openssl.org/index.php/Android

You would set CFLAGS and LDFLAGS to point to the needed include dirs and library paths for OSSL, something
Like what is mentioned in the " Install the OpenSSL Library" and " Compile and Link against the Library" in
The aforementioned OpenSSL Android instructions link.

The example Andreas shows is built using a "Blueprint" file. It was part of the switch that occurred
to in-aosp-tree projects when they went to this Ninja Kata build system. However, AFAIK, the NDK
has stayed Make. So that example, won't really be a drop in for an NDK build. I can throw together
a proper Android.mk and add it to the project. We can probably setup a built in Github Actions for
it as well.

Hello All,

We are trying to use  TPM2.0 on Android, would like to port TPM2 TSS on to it,
could any of you suggest any tutorials on the NDK Build compilation of TPM2 TSS and relevant details to use TPM2 TSS on Android
