I2P-Bote is a plugin for I2P that allows users to send and receive emails while preserving privacy. It does not need a mail server because emails are stored in a distributed hash table. They are automatically encrypted and digitally signed, which ensures no one but the intended recipient can read the email, and third parties cannot forge them.

• Themeable webmail interface
• User interface translated in many languages
• One-click creation of email accounts (called email identities)
• Emails can be sent under a sender identity, or anonymously
• ElGamal, Elliptic Curve, and NTRU Encryption
• Encryption and signing is transparent, without the need to know about PGP
• Delivery confirmation
• Basic support for short recipient names
• IMAP / SMTP

• Custom folders
• Sending and receiving via relays, similar to Mixmaster
• Lots of small improvements

• Java SDK (preferably Oracle/Sun or OpenJDK) 1.7.0 or higher
• Gradle 5.6.4 or higher

The build system is based on Gradle. There are several methods for setting Gradle up:

• It can be downloaded from the Gradle website.

• Most distributions will have Gradle packages. Be careful to check the provided version; Debian and Ubuntu have old versions in their main repositories. There is a PPA for Ubuntu with the latest version of Gradle.

• A Gradle wrapper is provided in the codebase. It takes all the same commands as the regular gradle command. The first time that any command is run, it will automatically download, cache and use the correct version of Gradle. This is the simplest way to get started with the codebase. To use it, replace gradle with ./gradlew (or ./gradlew.bat on Windows) in the commands below.

Gradle will pull dependencies over the clearnet by default. To use Tor, create a gradle.properties file in i2p.android.base containing:

```
systemProp.socksProxyHost=localhost
systemProp.socksProxyPort=9150
```

gradle :webapp:plugin

The plugin will be placed in i2p.i2p-bote/webapp/build/plugin.

gradle :webapp:war

The WAR will be placed in i2p.i2p-bote/webapp/build/libs.

Ensure you have an I2P router running locally with an I2CP server port open (on port 7654). Then run:

gradle :webapp:tomcatRunWar

This will build and run the WAR. (Jetty currently does not work.)

The data directory will be placed in i2p.i2p-bote/webapp/i2pbote; logs will be in i2p.i2p-bote/webapp/logs.

• I2P source
• Android SDK 29 or higher
• Android Build Tools 30.0.0 or higher
• Android Support Repository

Currently, the I2P upstream does not provide the latest I2P Android Client Library for some unknown reason. You have to build it by yourself. See the i2p.android.base repo for detail.

1. Download the Android SDK. The simplest method is to download Android Studio.

2. Create a local.properties file in i2p.i2p-bote/android containing:

   i2psrc=/path/to/i2p.i2p
   

3. If you want to use a local copy of the I2P Android client library, install it in your local Maven repository with:

   cd path/to/i2p.android.base
   ./gradlew client:installArchives
   

1. Create a local.properties file in i2p.i2p-bote containing:

   sdk.dir=/path/to/android-studio/sdk
   

2. gradle :android:assembleDebug

3. The APK will be placed in i2p.i2p-bote/android/build/outputs/apk.

1. Import i2p.i2p-bote into Android Studio. (This creates the local.properties file automatically).

2. Build and run the app (Shift+F10).

1. Create a signing.properties file in i2p.i2p-bote containing:

   STORE_FILE=/path/to/android.keystore
   STORE_PASSWORD=store.password
   KEY_ALIAS=key.alias
   KEY_PASSWORD=key.password
   

2. gradle assembleRelease

The links below only work within I2P, i.e., make sure you are running I2P and your browser is using the proxy at localhost:4444.
