- `doh_servers = false` (disable servers implementing the `DNS-over-HTTPS` protocol)

- `require_dnssec = true` (server must support `DNSSEC` security extension)

- `force_tcp = true` (fix for mobile data intial connection random issues if `routes` have been set and `skip_incompatible = true`, see [DNSCrypt/dnscrypt-proxy/discussions/2020](https://github.com/DNSCrypt/dnscrypt-proxy/discussions/2020))

- `timeout = 1000` (set the max. response time of a single DNS query from `5000` to `1000` ms.)

- `blocked_query_response = 'refused'` (set `refused` response to blocked queries)

- `# log_level = 0` (set the log level of the `dnscrypt-proxy.log` file to very verbose, but keep it disabled by default)

- `dnscrypt_ephemeral_keys = true` (create a new, unique key for every single DNS query)

- `bootstrap_resolvers = ['91.239.100.100:53', '89.233.43.71:53']` (use [UncensoredDNS (Anycast & Unicast)](https://blog.uncensoreddns.org/) instead [CloudFlare](https://archive.fo/tS1Ln))

- `netprobe_address = '91.239.100.100:53'` (use [UncensoredDNS (Anycast)](https://blog.uncensoreddns.org/) instead [CloudFlare](https://archive.fo/tS1Ln))

- `block_ipv6 = true` (immediately respond to IPv6-related queries with an empty response)

- `blocked-names.txt`, `blocked-ips.txt`, `allowed-names.txt` and `allowed-ips.txt` files enabled. (to know more specifics about this, please refer to the [Filters (optional)](https://github.com/quindecim/dnscrypt-proxy-android#filters-optional) section below)

- `anonymized_dns` feature enabled. (`routes` are indirect ways to reach DNSCrypt servers, each resolver has 2 relays assigned)

- `skip_incompatible = true` (skip resolvers incompatible with anonymization instead of using them directly)

- `direct_cert_fallback = false` (prevent direct connections through the resolvers for failed certificate retrieved via relay)


## Installation

**1.** Download the latest `dnscrypt-proxy-android-*.zip` file from the [Releases](https://github.com/quindecim/dnscrypt-proxy-android/releases/latest) page or from my [dnscrypt-proxy-android | CHANNEL](https://t.me/dnscrypt_proxy) on [Telegram](https://telegram.org/) and flash it with [Magisk](https://github.com/topjohnwu/Magisk):

```
Magisk > Modules > Install from storage > dnscrypt-proxy-android-*.zip
```

**2.** Reboot your device.

**3.** Test your DNS at https://dnsleaktest.com/


### Configuration (optional)

You can edit the `dnscrypt-proxy.toml` file as you wish located on `storage/emulated/0/dnscrypt-proxy` path.

For a more detailed configuration you can refer to the [official documentation](https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Configuration) or simply join our group on [Telegram](https://telegram.org/), at [dnscrypt-proxy-android | CHAT](https://t.me/qd_invitations).


### Filters (optional)

Filters are a powerful set of built-in features, that let you control exactly what domain names and IP addresses your device are allowed to connect to. This can be used to block ads, trackers, malware, or anything you don't want your device to load.
The module comes with the [filtering](https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Filters) feature enabled by default, that's why you can see some files, needed for this operation, inside the `/storage/emulated/0/dnscrypt-proxy` folder. The files are empty, out of the box they work as a placeholder, but they can be used to use dnscrypt-proxy as a blocking tool. To know more about it you can consult the official [documentation](https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Filters), or in a simpler way through my [repository](https://github.com/quindecim/block).

I'm also providing the `allowed-names.txt` and `blocked-names.txt` files regularly updated at [dnscrypt-proxy-filters | CHANNEL](https://t.me/dnscrypt_proxy_filters). The [sources](https://github.com/quindecim/block#sources) used for this merge are among the hardest on the web.

You can contribute to this blocklist at anytime, opening an [Issue](https://github.com/quindecim/dnscrypt-proxy-android/issues) here or simply reporting the issue at [dnscrypt-proxy-filters | CHAT](https://t.me/qd_invitations) on [Telegram](https://telegram.org/).
