IOCipher: Encrypted Virtual Disk -------------------------------- IOCipher is a virtual encrypted disk for apps without requiring the device to be rooted. It uses a clone of the standard java.io API for working with files. Just password handling & opening the virtual disk are what stand between developers and fully encrypted file storage. It is based on libsqlfs and SQLCipher. If you are using this in your app, we'd love to hear about it! Please send us an email at root@guardianproject.info Getting Supporting Libraries ---------------------------- IOCipher is built upon SQLCipher, which is required in order to use this library. You can get SQLCipher-for-Android here: http://sqlcipher.net/open-source For example, SQLCipher for Android v3.1.0 binary is available here: https://s3.amazonaws.com/sqlcipher/SQLCipher+for+Android+v3.1.0.zip And the signature is here: https://s3.amazonaws.com/sqlcipher/SQLCipher+for+Android+v3.1.0.zip.sig The releases should be signed by this key: ``` $ gpg --recv-keys D1FA3A2A97ED25C2 $ gpg --fingerprint support@zetetic.net pub 4096R/97ED25C2 2014-04-22 [expires: 2017-04-21] Key fingerprint = D83F 5F9E B811 D6E6 B4A0 D9C5 D1FA 3A2A 97ED 25C2 uid Zetetic LLC sub 3072R/67FD0322 2014-04-22 [expires: 2015-04-22] sub 3072R/D4DFEDA7 2014-04-22 [expires: 2015-04-22] sub 3072R/B1C49DF6 2014-04-22 [expires: 2015-04-22] ``` Building -------- This app relies on OpenSSL libcrypto, sqlcipher, and libsqlfs, which are all "native" C code that needs to be built before working with the Java. First, make sure you have the build prerequisites: apt-get install tcl libtool automake autoconf gawk libssl-dev Point `ant` to where your Android NDK is installed, either by setting `ndk.dir` in your local.properties or setting the environment variable: export ANDROID_NDK=/opt/android-ndk Now build everything: git clone https://github.com/guardianproject/IOCipher git submodule update --init --recursive android update lib-project --path . ant clean debug The iocipher.jar is in bin/. The shared library .so files are in libs/armeabi and the libsqlfs.a static library is in external/libsqlfs/.libs/libsqlfs.a. Building Native Bits for Eclipse -------------------------------- If you are using Eclipse with this library, you can have the NDK parts built as part of the Eclipse build process. You just need to set ANDROID_NDK in the "String Substitution" section of your Eclipse's workspace preferences. Otherwise, you can build the native bits from the Terminal using: make -C external ndk-build License ------- When taken as a whole, this project is under the the LGPLv3 license since it is the only license that is compatible with the licenses of all the components. The source code for this comes from a few different places, so there are a number of licenses for different chunks. * Apache 2.0 (Android Internals): Much of the code here is taken from the Android internals, so it has an Apache 2.0 license. * OpenSSL License: It is linked to the OpenSSL that is provided with Android, so it should be covered under Android's handling of the advertisement clause. * LGPL 2.1 (libsqlfs) * BSD-style (sqlcipher) Included shared library files ----------------------------- In `external/libs` are some binary .so files, these are all binaries pulled from other sources so that the C code can have something link against. `libcrypto.so` comes from Android emulators. They are included here so that the C code can link against openssl's libcrypto, which Android includes but does not expose in the NDK. If you want to build this library from source, then do this: ``` git clone https://github.com/guardianproject/openssl-android cd openssl-android ndk-build -j4 ``` These shared libraries _must_ not be included in any real app. Android provides `/system/lib/libcrypto.so` and you should get SQLCipher directly from the source, listed above.
