doh-client is a DNS over HTTPS client, which opens a local UDP (DNS) port and forwards all DNS queries to a remote HTTP/2.0 server.
By default the client will connect to the Cloudflare DNS service.
It uses Tokio for all asynchronous IO operations and Rustls to connect to the HTTPS server.
doh-client is written in Rust. To build it you need the Rust compiler and build system cargo.
$ cargo build
or to build it as release build
$ cargo build --release
To run the binary, you need one option (see Options)
$ ./doh-client --cafile /path/to/the/ca/file.pem
For example if you use Arch Linux then the following command uses the system cert store:
```
```
doh-client has one required option, --cafile which sets path to a pem file, which contains the trusted CA certificates.
```
$ ./doh-client --help
