# Introduction
DroidFS relies on modified versions of the original encrypted filesystems programs to open volumes. [CryFS](https://github.com/cryfs/cryfs) is written in C++ while [gocryptfs](https://github.com/rfjakob/gocryptfs) is written in [Go](https://golang.org). Thus, building DroidFS requires the compilation of native code. However, for the sake of simplicity, the application has been designed in a modular way: you can build a version of DroidFS that supports both Gocryptfs and CryFS, or only one of the two.
Moreover, DroidFS aims to be accessible to as many people as possible. If you encounter any problems or need help with the build, feel free to open an issue, a discussion, or contact me by [email](mailto:hardcore.sushi@disroot.org) or on [Matrix](https://matrix.org): @hardcoresushi:matrix.underworld.fr
# Setup
Install required packages:
```
$ sudo apt-get install openjdk-11-jdk-headless build-essential pkg-config git gnupg2 wget apksigner
```
You also need to manually install the [Android SDK](https://developer.android.com/studio/index.html#command-tools) and the [Android Native Development Kit (NDK)](https://developer.android.com/ndk/downloads) (r23 versions are recommended).
If you want a support for Gocryptfs volumes, you must install [Go](https://golang.org/doc/install) and libssl:
```
$ sudo apt-get install golang-go libssl-dev
```
The code should be authenticated before being built. To verify the signatures, you will need my PGP key:
```
$ gpg --keyserver hkps://keyserver.ubuntu.com --recv-keys AFE384344A45E13A
```
Fingerprint: `B64E FE86 CEE1 D054 F082 1711 AFE3 8434 4A45 E13A` \

# Download sources
Download DroidFS source code:
```
$ git clone --depth=1 https://github.com/hardcore-sushi/DroidFS.git
```
Verify sources:
```
$ cd DroidFS
$ git verify-commit HEAD
```
__Don't continue if the verification fails!__
Initialize submodules:
```
$ git submodule update --depth=1 --init
```
[FFmpeg](https://ffmpeg.org) is needed to record encrypted video:
```
$ cd app/ffmpeg
$ git clone --depth=1 https://git.ffmpeg.org/ffmpeg.git
```
If you want Gocryptfs support, you need to download OpenSSL:
```
$ cd ../libgocryptfs
$ wget https://www.openssl.org/source/openssl-1.1.1p.tar.gz
```
Verify OpenSSL signature:
```
$ wget https://www.openssl.org/source/openssl-1.1.1p.tar.gz.asc
$ gpg --verify openssl-1.1.1p.tar.gz.asc openssl-1.1.1p.tar.gz
```
Continue **ONLY** if the signature is **VALID**.
```
$ tar -xzf openssl-1.1.1p.tar.gz
```
If you want CryFS support, initialize libcryfs:
```
$ cd app/libcryfs
$ git submodule update --depth=1 --init
```
# Build
Retrieve your Android NDK installation path, usually something like `/home/\<user\>/Android/SDK/ndk/\<NDK version\>`. Then, make it available in your shell:
```
$ export ANDROID_NDK_HOME="<your ndk path>"
```
Start by compiling FFmpeg:
```
$ cd app/ffmpeg
$ ./build.sh ffmpeg
```
## libgocryptfs
This step is only required if you want Gocryptfs support.
```
$ cd app/libgocryptfs
$ OPENSSL_PATH="./openssl-1.1.1p" ./build.sh
```
## Compile APKs
Gradle build libgocryptfs and libcryfs by default.
To build DroidFS without Gocryptfs support, run:
```
$ ./gradlew assembleRelease -PdisableGocryptfs=true
```
To build DroidFS without CryFS support, run:
```
$ ./gradlew assembleRelease -PdisableCryFS=true
```
If you want to build DroidFS with support for both Gocryptfs and CryFS, just run:
```
$ ./gradlew assembleRelease
```
# Sign APKs
If the build succeeds, you will find the unsigned APKs in `app/build/outputs/apk/release/`. These APKs need to be signed in order to be installed on an Android device.
If you don't already have a keystore, you can create a new one by running:
```
$ keytool -genkey -keystore <output file> -alias <key alias> -keyalg EC -validity 10000
```
Then, sign the APK with:
```
$ apksigner sign --out droidfs.apk -v --ks <keystore> app/build/outputs/apk/release/<unsigned apk file>
```
Now you can install `droidfs.apk` on your device.

# DroidFS
DroidFS is an alternative way to use encrypted overlay filesystems on Android that uses its own internal file explorer instead of mounting virtual volumes.
It currently only works with [gocryptfs](https://github.com/rfjakob/gocryptfs) but support for [CryFS](https://github.com/cryfs/cryfs) could be added in the future.
It currently supports [gocryptfs](https://github.com/rfjakob/gocryptfs) and [CryFS](https://github.com/cryfs/cryfs) (alpha).

# Limitations
DroidFS use some parts of the original gocryptfs code, which is designed to run on Linux x86 systems: it accesses the underlying file system with file paths and syscalls. However in Android, you can't access other apps files with file paths. Instead, you must use the [ContentProvider](https://developer.android.com/guide/topics/providers/content-providers) API. And obviously, the original gocryptfs code doesn't work with this API. This is why DroidFS can't open volumes provided by other applications, such as cloud storage clients. You can only use DroidFS with volumes located on shared storage or in the app's internal storage (hidden volumes). External storage such as SD cards are only supported in read-only access for now.
DroidFS works as a wrapper around modified versions of the original encrypted container implementations ([libgocryptfs](https://forge.chapril.org/hardcoresushi/libgocryptfs) and [libcryfs](https://forge.chapril.org/hardcoresushi/libcryfs)). These programs were designed to run on standard x86 Linux systems: they access the underlying file system with file paths and syscalls. However, on Android, you can't access files from other applications using file paths. Instead, one has to use the [ContentProvider](https://developer.android.com/guide/topics/providers/content-providers) API. Obviously, neither Gocryptfs nor CryFS support this API. As a result, DroidFS cannot open volumes provided by other applications (such as cloud storage clients), nor can it allow other applications to access encrypted volumes once opened.
# Build
Most of the original gocryptfs code was used as is (written in Go) and compiled to native code. That's why you need [Go](https://golang.org) and the [Android Native Development Kit (NDK)](https://developer.android.com/ndk/) to build DroidFS from source.
Due to Android's storage restrictions, encrypted volumes located on SD cards must be placed under `/Android/data/sushi.hardcore.droidfs/` if you want DroidFS to be able to modify them.
#### Install dependencies
On debian:
```
$ sudo apt-get install build-essential pkg-config libssl-dev
```
Install [Go](https://golang.org/doc/install):
```
$ sudo apt-get install golang-go
```
You also need to install the Android SDK build tools and the [Android NDK](https://developer.android.com/studio/projects/install-ndk).
#### Download Sources
```
$ git clone --recurse-submodules https://github.com/hardcore-sushi/DroidFS.git
$ cd DroidFS
```
[libgocryptfs](https://forge.chapril.org/hardcoresushi/libgocryptfs) needs OpenSSL:
```
$ cd app/libgocryptfs
$ wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz
```
Verify OpenSSL signature:
```
$ wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz.asc
$ gpg --verify openssl-1.1.1n.tar.gz.asc openssl-1.1.1n.tar.gz
```
Continue **ONLY** if the signature is **VALID**.
```
$ tar -xvzf openssl-1.1.1n.tar.gz
```
DroidFS also need [FFmpeg](https://ffmpeg.org) to record encrypted video:
```
$ cd app/ffmpeg
$ git clone --depth=1 https://git.ffmpeg.org/ffmpeg.git
```
#### Generate a keystore
APKs must be signed to be installed on an Android device. If you don't already have a keystore, you can generate one by running:
```
$ keytool -genkey -keystore <output file> -alias <key alias> -keyalg EC -validity 10000
```
#### Build
Retrieve your Android NDK installation path, usually something like "/home/\<user\>/Android/SDK/ndk/\<NDK version\>". Now you can build libgocryptfs:
```
$ cd DroidFS/app/libgocryptfs
$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1n" ./build.sh
```
Then FFmpeg:
```
$ cd app/ffmpeg
$ env ANDROID_NDK_HOME="<your ndk path>" ./build.sh ffmpeg
```
Finally, compile the app:
```
$ ./gradlew assembleRelease
```
If the build succeeds, you will find the unsigned APKs in `app/build/outputs/apk/release/`. You need to sign them in order to install the app:
```
$ apksigner sign --out droidfs.apk -v --ks <keystore> app/build/outputs/apk/release/<unsigned apk file>
```
Now you can install `droidfs.apk` on your device.

DroidFS is an alternative way to use encrypted overlay file-systems on Android that uses its own internal file explorer instead of mounting virtual volumes. This allows you to store files in encrypted virtual volumes that other apps can't decrypt.
Currently, DroidFS supports only <b>gocryptfs</b>. This algorithm protects file contents and file names but doesn't hide directory structure or file sizes. If you want more details, take a look at their GitHub repository: https://github.com/rfjakob/gocryptfs
Currently, DroidFS supports the following encrypted containers:
- gocryptfs (https://github.com/rfjakob/gocryptfs): encrypts file contents and file names but doesn't hide directory structure or file sizes.
- CryFS (https://github.com/cryfs/cryfs): slower, but encrypts everything and obfuscates file sizes.
<b>Features:</b>
- Volumes fully compatibles with their original algorithm implementation
- Internal opening of images, videos, audios and text files
- Common file and folder operations: copy, move, rename, delete
- Volume password changing
- Volumes fully compatibles with their original implementations
- Internal opening of images, videos, audios, PDF and text files
- Common file manager operations: copy, move, rename, create, delete
- Internal and shared storage support
- Cross-volume imports
- Internal camera to take encrypted pictures or videos
- Theme color fully customizable
- Internal camera to take encrypted pictures and videos
<b>Permissions:</b>
<b>Read & write access to shared storage:</b> required to create, open and modify volumes and import/export files to/from volumes.
