I2P Easy-Install Bundle for Windows, (Formerly)I2P Browsing Profile for Firefox

Features:

• Automatically select an up-to-date, secure browser from the host platform, with Tor Browser and Firefox preferred.
• Automatically configure a profile for I2P
• Automatically block-list all non-I2P local destinations
• Enable first-party isolation, anti-fingerprinting, letterboxing, fusion, other privacy and security options
• Automatically sandbox I2P, Non-I2P, and I2P-Application cookiestores

Build Dependencies:

SHORTCUT: All the build artifacts can be produced by the description in the .yaml files in .github/workflows. These can be run on Github's infrastructure, or on a local(Windows) PC using https://github.com/nektos/act. Doing things this way deals with all the dependency issues that Windows doesn't really give you a good way to deal with automatically. It also guarantees that the same base container and environment gets used for every build no matter what machine it runs on. I highly recommend you use either Github CI or nektos/act for dev builds of this software, as it automates literally every one of the steps. CI-based builds follow the WSL version of the instructions.

To build this, you will need the following software packages (all available in Debian and Ubuntu, see WSL section below):

• make
• nsis
• dos2unix
• curl
• jq

These need to be installed in the environment where the NSIS Package is build, NOT the environment where the java package is built. These may be different, because you will need to use a system which provides a Unix-like environment on top of a Windows system. You can use WSL or Cygwin, and more detailed instructions are provided below.

Building for Windows target from Linux is not possible unless you obtain a Windows package from my github.

In addition, you will need the NSIS plugin "ShellExecAsUser" which you can get from the NSIS Wiki Page. In order to install the plugin on Debian, Ubuntu, or using WSL, you can download the: 7zip release and copy the content of Plugins to /usr/share/nsis/Plugins.

cp -rv Plugins/* /usr/share/nsis/Plugins/

Including a jpackaged I2P Router

Prerequisites: You need to have OpenJDK 14 or greater installed and configured with your %JAVA_HOME% environment variable configured and %JAVA_HOME%/bin on your %PATH%. You need to have Apache Ant installed and configured with %ANT_HOME% environment variable configured and %ANT_HOME%/bin on your %PATH%. You must have Cygwin installed. You must have NSIS.exe installed and makensis available on your %PATH%. You must have Git for Windows installed. When installing git for Windows, you should select "Checkout as is, commit as is" and leave line-endings alone.

The Windows build tools listed above must be installed on the Windows host machine.

TODO: Add links to the respective instructions for each of these.

Note that after the dependencies are installed, this step is automated with ./buildscripts/build.sh.

In order to include a jpackaged(dependency-free) I2P router in the Profile Bundle you will need to build the jpackaged I2P router as an "App Image" on a Windows system and place it into a directory called I2P in your i2p.firefox checkout. Building without a jpackage is no longer supported.

Assuming a working java and jpackage environment on your Windows system, the following command should generate a suitable "App Image" in a directory called "I2P."

    export I2P_VERSION=0.9.49
    cp -R ../i2p.i2p/pkg-temp/lib build/lib
    jpackage --type app-image --name I2P --app-version "$I2P_VERSION" \
      --verbose \
      --resource-dir build/lib \
      --input build/lib --main-jar router.jar --main-class net.i2p.router.RouterLaunch

Transfer the I2P directory to the machine where you build i2p.firefox if necessary, then complete the regular build instructions. If a jpackaged I2P router isn't present to use at build time, the inclusion will be skipped automatically with a non-fatal warning.

Pre-built app-images are available from my daily releases at:

    https://github.com/eyedeekay/i2p.plugins.firefox/releases/

Windows Build

After installing the dependencies and completing the preparations, just run make. This will produce the install.exe - the windows installer, which sets up the shortcuts to launch Firefox on Windows. Building without a jpackage is no longer supported.

When generating a build it's important to make sure that the licenses for all the bundled softare are included. This should happen automatically. When bundling software, describe the terms and where they are applied in the LICENSE.index, then add the full license to the licenses directory. Then, add the full license to the cat command in the build/licenses make target. The build/licenses target is run automatically during the build process.

End-to-End Windows build process using WSL(Recommended)

See config.sh and i2pversion for instructions on how to tweak the build process. File an issue if you need help.

If you've already done this once, you can just use: ./unsigned.sh in git bash to automatically build an installer. If you are using this method, you may use the makensis and make from Ubuntu in WSL.

1. Set up Windows Subsystem for Linux per Microsoft's instructions

2. Install Ubuntu Focal per Microsoft's instructions

3. Open Git Bash.

4. Install prerequisites wsl sudo apt-get update && sudo apt-get install make nsis nsis-pluginapi dos2unix curl jq

5. Clone i2p.i2p and i2p.firefox

   git clone https://github.com/i2p/i2p.i2p
   git clone https://github.com/i2p/i2p.firefox
   

6. Move to the i2p.i2p directory. Build the .jar files required to build the App Image inside i2p.i2p. Return to home.

   cd i2p.i2p
   ant clean pkg
   cd ..
   

7. Move into the i2p.firefox directory. Run the ./buildscripts/build.sh script.

   cd i2p.firefox
   ./buildscripts/build.sh
   

8. Compile the NSIS installer using WSL.

   wsl make
   

End-to-End Windows build process using Cygwin(More difficult than WSL for now)

I highly recommend you look into the Chocolatey package manager, which makes it much easier to configure these tools and keep them up to date.

Prerequisites: In addition to the other prerequisites, you will need to to have make installed with cygwin. For our purposes, as long as everything else is set up and you're using git bash, that is enough to make the scripts compatible with cygwin. Cygwin builds without git bash are not likely to work.

1. Run the Cygwin setup-$arch.exe for your platform to set up new packages. Select the make jq dos2unix and curl packages.

2. Open a cygwin terminal.

3. Clone i2p.i2p and i2p.firefox

    git clone https://github.com/i2p/i2p.i2p
    git clone https://github.com/i2p/i2p.firefox
   

4. Move to the i2p.i2p directory. Build the .jar files required to build the App Image inside i2p.i2p. Return to home.

    cd i2p.i2p
    ant clean pkg
    cd ..
   

5. Move into the i2p.firefox directory. Run the ./buildscripts/unsigned.sh script.

    cd i2p.firefox
    ./buildscripts/unsigned.sh
   

Doing a Release

Once you have the installer .exe file produced by NSIS, you're almost ready to do a release. As a final step, someone must sign the .exe file using a Certificate which Windows will recognize. The current signer of the Windows bundle is Zlatinb. Standard Windows signing tools are used.

./release.sh

produces the binary and the su3.

Issues

To report issues against this browser profile, please file issues at the official Gitlab or the Github Mirror. Issues pertaining to the plugins may be reported to their upstream maintainers if it's determined that our configuration is not at fault.

This profile manager makes use of a set of browser extensions which are largely the work of others. It makes use of dependencies that are the work of others.
