DNSCrypt Client Usage

Please get your own DNSCrypt fingerprint first:

$ cat $DNSCRYPT_KEY_PATH/fingerprint
Provider public key fingerprint : 4365:1587:E7A0:8C7C:1759:D300:6218:89AE:5999:42CA:562E:CB00:03E5:2147:A850:E191

ATTENTION: It would show a different fingerprint, please replace the fingerprint below with your own one.
Then, run dnscrypt-proxy on the client side, for example:

dnscrypt-proxy --local-address=127.0.0.1:53 --resolver-address=$DNS_SERVER:443 --provider-name=2.dnscrypt-cert.example.org --provider-key=4365:1587:E7A0:8C7C:1759:D300:6218:89AE:5999:42CA:562E:CB00:03E5:2147:A850:E191

NOTE: You need to replace $DNS_SERVER with your server IP address.
