DNSCrypt Setup

Update

These days instead of the below, I recommend using my setup-dns script from my dotfiles which will setup encrypted DNS for you automatically.

DNSCrypt

MacOS

Install DNSCrypt:

brew install dnscrypt-proxy

Use my DNSCrypt configuration:

wget -O /usr/local/etc/dnscrypt-proxy.toml -N https://gist.githubusercontent.com/balupton/48057270a67d70e2ac984fdfa475ad29/raw/dnscrypt-proxy.toml

Or setup your DNSCrypt configuration manually:

edit /usr/local/etc/dnscrypt-proxy.toml 

Test the configuration:

sudo dnscrypt-proxy -config /usr/local/etc/dnscrypt-proxy.toml

Register and start the service:

sudo brew services start dnscrypt-proxy

iOS, Android

Purchase AdGuard Pro for iOS or AdGuard for Android, which functions as a VPN tunnel, uses your chosen DNSCrypt servers regardless of WiFi network, while blocking ads.

## This is an example configuration file.
## You should adjust it to your needs, and save it as "dnscrypt-proxy.toml"

## List of servers to use
## If this line is commented, all registered servers matching the require_* filters

## The proxy will automatically pick the fastest, working servers from the list.
## Remove the leading # first to enable this; lines starting with # are ignored.
# If you are thinking of disabling family filtering, think of your future
# an hour will be lost in search for happiness
# then several hours will be felt feeling icky and smelly with a sore back from poor posture
# write in your journal instead to address the causes for why you are seeking this escape

## List of local addresses and ports to listen to. Can be IPv4 and/or IPv6.
## To only use systemd activation sockets, use an empty set: []

## Maximum number of simultaneous client connections to accept
max_clients = 250
## Require servers (from static + remote sources) to satisfy specific properties

## Fallback resolver
## This is a normal, non-encrypted DNS resolver, that will be only used
## for one-shot queries when retrieving the initial resolvers list, and
## only if the system DNS configuration doesn't work.
## No user application queries will ever be leaked through this resolver,
## and it will not be used after IP addresses of resolvers URLs have been found.
## It will never be used if lists have already been cached, and if stamps
## don't include host names without IP addresses.
## It will not be used if the configured system DNS works.
## A resolver supporting DNSSEC is recommended. This may become mandatory.
fallback_resolver = '9.9.9.9:53'
## Never try to use the system DNS settings; unconditionally use the
## fallback resolver.

#########################
# Filters #
#########################
## Immediately respond to IPv6-related queries with an empty response
## This makes things faster when there is no IPv6 connectivity, but can
## also cause reliability issues with some stub resolvers. In
## particular, enabling this on macOS is not recommended.

# Route queries for specific domains to a dedicated set of servers #
##################################################################################
## Example map entries (one entry per line):
## example.com 9.9.9.9
## example.net 9.9.9.9,8.8.8.8
# forwarding_rules = 'forwarding-rules.txt'
###############################
# Cloaking rules #
###############################
## Cloaking returns a predefined address for a specific name.
## In addition to acting as a HOSTS file, it can also return the IP address
## of a different name. It will also do CNAME flattening.
##
## Example map entries (one entry per line)
## example.com 10.1.1.1
## www.google.com forcesafesearch.google.com
# cloaking_rules = 'cloaking-rules.txt'

## Enable a DNS cache to reduce latency and outgoing traffic

## Maximum TTL for cached entries

# Query logging #
###############################
## Log client queries to a file
[query_log]
## Path to the query log file (absolute, or relative to the same directory as the executable file)
# file = 'query.log'
## Query log format (currently supported: tsv and ltsv)
format = 'tsv'
## Do not log these query types, to reduce verbosity. Keep empty to log everything.
# ignored_qtypes = ['DNSKEY', 'NS']
############################################
# Suspicious queries logging #
############################################
## Log queries for nonexistent zones
## These queries can reveal the presence of malware, broken/obsolete applications,
## and devices signaling their presence to 3rd parties.
[nx_log]
## Path to the query log file (absolute, or relative to the same directory as the executable file)
# file = 'nx.log'
## Query log format (currently supported: tsv and ltsv)
format = 'tsv'
######################################################
# Pattern-based blocking (blacklists) #
######################################################
## Blacklists are made of one pattern per line. Example of valid patterns:
##
## example.com
## *sex*
## ads.*
## ads*.example.*
## ads*.example[0-9]*.com
##
## Example blacklist files can be found at https://download.dnscrypt.info/blacklists/
## A script to build blacklists from public feeds can be found in the
## `utils/generate-domains-blacklists` directory of the dnscrypt-proxy source code.
[blacklist]
## Path to the file of blocking rules (absolute, or relative to the same directory as the executable file)
# blacklist_file = 'blacklist.txt'
## Optional path to a file logging blocked queries
# log_file = 'blocked.log'
## Optional log format: tsv or ltsv (default: tsv)
# log_format = 'tsv'
###########################################################
# Pattern-based IP blocking (IP blacklists) #
###########################################################
## IP blacklists are made of one pattern per line. Example of valid patterns:
##
## 127.*
## fe80:abcd:*
## 192.168.1.4
[ip_blacklist]
## Path to the file of blocking rules (absolute, or relative to the same directory as the executable file)
# blacklist_file = 'ip-blacklist.txt'
## Optional path to a file logging blocked queries
# log_file = 'ip-blocked.log'
## Optional log format: tsv or ltsv (default: tsv)
# log_format = 'tsv'
##########################################
# Time access restrictions #
##########################################
## One or more weekly schedules can be defined here.
## Patterns in the name-based blocklist can optionally be followed with @schedule_name
## to apply the pattern 'schedule_name' only when it matches a time range of that schedule.
##
## For example, the following rule in a blacklist file:
## *.youtube.* @time-to-sleep
## would block access to Youtube only during the days, and period of the days
## define by the 'time-to-sleep' schedule.
##
## {after='21:00', before= '7:00'} matches 0:00-7:00 and 21:00-0:00
## {after= '9:00', before='18:00'} matches 9:00-18:00

# thu = [{after='21:00', before='7:00'}]
# fri = [{after='23:00', before='7:00'}]
# sat = [{after='23:00', before='7:00'}]

# fri = [{after='9:00', before='17:00'}]
#########################
# Servers #
#########################
## Remote lists of available servers
## Multiple sources can be used simultaneously, but every source
## requires a dedicated cache file.
##
## Refer to the documentation for URLs of public sources.
##
## A prefix can be prepended to server names in order to
## avoid collisions if different sources share the same for
## different servers. In that case, names listed in `server_names`
## must include the prefixes.
##
## If the `url` property is missing, cache files and valid signatures
## must be already present; This doesn't prevent these cache files from
## expiring after `refresh_delay` hours.
[sources]
## An example of a remote source
[sources.'public-resolvers']
url = 'https://download.dnscrypt.info/resolvers-list/v2/public-resolvers.md'
cache_file = 'public-resolvers.md'
minisign_key = 'RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3'
refresh_delay = 72
prefix = ''
## Another example source, with resolvers censoring some websites not appropriate for children
## This is a subset of the `public-resolvers` list, so enabling both is useless
# [sources.'parental-control']
# url = 'https://download.dnscrypt.info/resolvers-list/v2/parental-control.md'
# cache_file = 'parental-control.md'
# minisign_key = 'RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3'
## Optional, local, static list of additional servers
## Mostly useful for testing your own servers.
[static]
# [static.'google']
