Frank Denis 2d1dd7eaab Add Stretch-Hash-and-Truncate option for extreme DNS privacy
This works over DNSCrypt and DoH, but requires a specifically configured
server.

Instead of sending the actual DNS queries, the SH-T system works as follows:

Step 1: the client query is evaluated through Argon2id, a military-grade,
memory-hard, CPU-hard stretching function. This makes it very expensive
for an attacker to find the original query, even using GPUs and ASICs.
For post-quantum resistance, we use it to generate a 1024-bit key.

Step 2: in case the Argon2id algorithm has a vulnerability, or, since this
is a popular function used for hashing passwords and for cryptocurrencices,
and people may have built rainbow tables already, we use a hash function over
the result of the previous function. This immediately defeats rainbow tables.

Step 3: the output of the hash function is truncated to 64-bit.
Due to a property of this operation known as collision-misresistance, and even
if the previous steps fail due to a nation-state actor, it is impossible for a
server operator to prove what exact query was originally sent by a client.

This feature is experimental.

dnscrypt-proxy 2

DNSCrypt-Proxy Release Build Status #dnscrypt-proxy:matrix.org

Overview

A flexible DNS proxy, with support for modern encrypted DNS protocols such as DNSCrypt v2 and DNS-over-HTTPS.

Download the latest release

Available as source code and pre-built binaries for most operating systems and architectures (see below).

Features

  • DNS traffic encryption and authentication. Supports DNS-over-HTTPS (DoH) using TLS 1.3, and DNSCrypt.
  • DNS query monitoring, with separate log files for regular and suspicious queries
  • Filtering: block ads, malware, and other unwanted content. Compatible with all DNS services
  • Time-based filtering, with a flexible weekly schedule
  • Transparent redirection of specific domains to specific resolvers
  • DNS caching, to reduce latency and improve privacy
  • Local IPv6 blocking to reduce latency on IPv4-only networks
  • Load balancing: pick a set of resolvers, dnscrypt-proxy will automatically measure and keep track of their speed, and balance the traffic across the fastest available ones.
  • Cloaking: like a HOSTS file on steroids, that can return preconfigured addresses for specific names, or resolve and return the IP address of other names. This can be used for local development as well as to enforce safe search results on Google, Yahoo and Bing.
  • Automatic background updates of resolvers lists
  • Can force outgoing connections to use TCP
  • Supports SOCKS proxies
  • Compatible with DNSSEC
