Onion Wrapper

A Java library providing a wrapper for running a Tor client on Android, Unix and Windows. The wrapper can be used for running hidden services.

The library supports the obfs4, meek_lite and snowflake pluggable transports.

Binaries for Tor and pluggable transports are not included. They can be found in the following Maven artifacts: org.briarproject:{tor,obfs4proxy,snowflake}-{android,linux,windows}. The obfs4proxy artifact provides obfs4 and meek_lite.

On Android, the library uses dont-kill-me-lib to hold a wake lock whenever Tor's network connection is enabled. The helper classes in dont-kill-me-lib can be used to work around certain manufacturer-specific power management restrictions that would prevent Tor from running in the background for long periods.
