dnscrypt-proxy-static

This is a fork of dnscrypt-proxy with libsodium source code bundled in, removing the need to compile it separately when cross-compiling dnscrypt-proxy for android and other platforms.

Android compile instructions

First things first, download Android NDK from here and unpack it somewhere. I'll assume you unpacked it into $HOME/android-ndk-r14b.

You will also need autoconf, automake, libtool and pkg-config to run autoreconf.

git clone https://github.com/AdguardTeam/dnscrypt-proxy-static
cd dnscrypt-proxy-static
export ANDROID_NDK_HOME=$HOME/android-ndk-r14b ## location of android NDK
autoreconf -f -i -v
dist-build/android-arm.sh
dist-build/android-armv7-a.sh
dist-build/android-armv8-a.sh
dist-build/android-mips32.sh
dist-build/android-mips64.sh
dist-build/android-x86.sh
dist-build/android-x86-64.sh

After everything compiles, there will be .zip files for each android architecture in current directory.

Original readme is kept below to avoid merge conflicts with upstream

DNSCrypt is a protocol for securing communications between a client and a DNS resolver, using high-speed high-security elliptic-curve cryptography.

While not providing end-to-end security, it protects the local network, which is often the weakest point of the chain, against man-in-the-middle attacks.

dnscrypt-proxy is a client-implementation of the protocol. It requires a DNSCrypt server on the other end.

Plugins

Aside from implementing the protocol, dnscrypt-proxy can be extended with plug-ins, and gives a lot of control on the local DNS traffic:

• Review the DNS traffic originating from your network in real time, and detect compromised hosts and applications phoning home.
• Locally block ads, trackers, malware, spam, and any website whose domain names or IP addresses match a set of rules you define.
• Prevent queries for local zones from being leaked.
• Reduce latency by caching resposes and avoiding requesting IPv6 addresses on IPv4-only networks.
• Force traffic to use TCP, to route it through TCP-only tunnels or Tor.
