This fork is the last commit prior to making dnscrypt run as a "service", which caused dnsmasq to restart whenever dnscrypt was started.

To resolve all problems associated with installing Dnscrypt-Proxy with Entware (or similar) along with setting up various scripts to handle dnscrypt-proxy starting up including the ntp issue, this installer of dnscrypt-proxy resolves all these concerns... The only requirement is an Asus Router flashed with custom Asuswrt-Merlin Firmware.

Requirements:

• ARM based ASUS routers that use Asuswrt-Merlin Firmware
• JFFS support and enabled

Incompatibilities:

• No known issue

Current features:

• dnscrypt-proxy version 2 with ODoH, DoH, and DNSCrypt version 2 protocols, multiple resolvers, and other features
• Running as nobody through nonroot binary (using --user requires change to passwd)
• Support ARM based routers
• Support OpenDNS dynamic IP update by entering your OpenDNS account information
• Handling ntp update at router boot up by starting dnscrypt-proxy with cert_ignore_timestamp option
• Redirect all DNS queries on your network to dnscrypt if user chooses to using DNS Filter Option
• Install haveged/rngd for better speed with dnscrypt and other cryptographic applications
• Support various HW RNG such as TrueRNG (tested with v3), TrueRNGpro, OneRNG, EntropyKey
• Ability to setup a swap file
• Ability to setup timezone file (/etc/localtime) used by dnscrypt-proxy and other apps
• Ability to reconfigure dnscrypt-proxy without reinstalling unlike previous installer for dnscrypt-proxy version 1.x.x
• Ability to configure anonymized relay support per Dnscrypt server through menu option or Wildcard Relay Support to cover all dnscrypt servers when automatic is selected.
• Support for NextDNS.io Account SDNS stamp as Static server.
• Support for addition of multiple static servers using SDNS Stamp and Custom Server Naming that can be mixed with servers on the resolvers list.
• Improved Installer/Update/Backup Functions.

Install/Update/Reconfig/Uninstall:

Run this command from ssh shell and following the prompt for dnscrypt-proxy version 2:

curl -L -s -k -O https://raw.githubusercontent.com/rugabunda/dnscrypt-asuswrt-installer/master/installer && sh installer ; rm installer

User can safely update from dnscrypt-proxy version 1 to version 2 with above command.

How to check if it works

If you use OpenDNS, run this command on Windows cmd

nslookup -type=txt debug.opendns.com

You should see something like

"dnscrypt enabled (717473654A614970)"

in result.

Otherwise running this command:

pidof dnscrypt-proxy

will return a number.

How I made this:

• Use dnscrypt-proxy binary packages from https://github.com/jedisct1/dnscrypt-proxy
• Compiling and stripping required binaries using firmware building toolchain from asuswrt-merlin
• I wrote the installer script with stuff inspired from entware-setup.sh from asuswrt-merlin
• You can look at all the stuff here https://github.com/thuantran/dnscrypt-asuswrt-installer
