A port of the whole gnupg 2.1 suite to Android.
We would like to target as many Android platforms as possible. Currently there are two limiting APIs:
- regex: provided in Android 2.2, SDK android-8 and above
- pthread_rwlock*: provided in Android 2.3, SDK android-9 and above
regex could easily be included in the build, pthread_rwlock* would be more difficult.
On Debian/Ubuntu/Mint/etc.:
sudo apt-get install autoconf automake libtool transfig wget patch \
texinfo ant gettext build-essential ia32-libs bison
On Fedora 17 x64:
sudo yum install ncurses-libs.i686 libstdc++.i686 libgcc.i686 zlib.i686 gcc.i686
Install the Android NDK for the command line version, and the Android SDK for the Android app version:
SDK: http://developer.android.com/sdk/ NDK: http://developer.android.com/sdk/ndk/
Update the git submodules:
git submodule --init update
To compile the components individually you can use commands like:
make -C external/ gnupg-install
make -C external/ gnupg-static
make -C external/ gpgme-install
The results will be in external/data/data/info.guardianproject.gpg
make -C external/ android-assets
make -C external/ tests
ndk-build
android update project --path . --target android-8 \
--name GnuPrivacyGuard
ant clean debug
make -C external/
ndk-build
android update project --path . --target android-8 \
--name GnuPrivacyGuard
ant clean debug
Testing pinentry is easiest on a rooted device
adb shell
$ su
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/data/info.guardianproject.gpg/app_opt/lib
export PATH=$PATH:/data/data/info.guardianproject.gpg/app_opt/bin
export HOME=/data/data/info.guardianproject.gpg/app_home
export GNUPGHOME=/data/data/info.guardianproject.gpg/app_home
# to test pinentry we want to import a secret key
# start adb logcat in another terminal so you dont miss the action
gpg2 --import /data/data/info.guardianproject.gpg/app_opt/tests/pinentry/secret-keys.gpg
