I'm not a paranoiac, and I certainly don't feel inclined to /hide/ from anyone, but that's not a reason not to protect my DNS queries from a simple snoop by unscrupulous ISPs. I simply prefer good network topology and security to convenience. With OpenBSD, I can have both security AND convenience with only a minimal amount of fuss. Why use anything else?
There are some caveats here, but the scope of those is beyond the point of this writing.
First, you'll need to install dnscrypt-proxy. If you don't have PKG_PATH defined, you can simply pull it directly like this:
pkg_add -v http://ftp.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -m`/dnscrypt-proxy
If you find you want the latest version of dnscrypt-proxy (1.9.4 as of this writing), follow this script:
# groupadd -g 688 _dnscrypt-proxy
# useradd -g _dnscrypt-proxy -s /sbin/nologin -u 688 -d /var/empty -c "dnscrypt-proxy user" -L daemon _dnscrypt-proxy
# cd /tmp
# ftp https://download.dnscrypt.org/dnscrypt-proxy/dnscrypt-proxy-1.9.4.tar.gz
# tar -zxvpf dnscrypt-proxy-1.9.4.tar.gz
# cd dnscrypt-proxy-1.9.4
# ./configure
# make
# make install
Next, you'll need to decide which DNS server you'd like to use. A CSV list can be found in /usr/local/share/dnscrypt-proxy/dnscrypt-resolvers.csv. For the sake of this discussion, I'm going to use the first one in the list, adamas. (No particular reason, it was simply first)
Next, start dnscrypt-proxy as user _dnscrypt-proxy (automatically added via pkg installation or script above) with the following command:
/usr/local/sbin/dnscrypt-proxy -l /var/log/dnscrypt-proxy.log -u _dnscrypt-proxy -d -a 127.0.0.1:54 -R adamas
This will allow us to monitor /var/log/dnscrypt-proxy.log for errors during the testing sequences. Once any errors have been located and resolved, you can switch the -l to /dev/null. Personally, I prefer to keep a log file, but that's your decision to make.
Now edit the default unbound configuration at /var/unbound/etc/unbound.conf, you'll obviously need to change your local interface IP if you plan to allow the rest of your network to access it. Mine is 172.16.18.1/24.
server:
interface: 172.16.18.1
interface: 127.0.0.1
access-control: 172.16.18.0/24 allow
do-not-query-localhost: no
hide-identity: yes
hide-version: yes
forward-zone:
name: "."
forward-addr: 127.0.0.1@54
Edit your /etc/resolv.conf to point to 127.0.0.1, then start unbound (/etc/rc.d/unbound -f).
To test, I use tcpdump to examine outbound packets on port 5678 (you'll need to examine the line in the CSV file mentioned above to find the correct port). If you make a DNS request, and see traffic on that port to the server listed in the /var/log/dnscrypt-proxy.log, you're probably set. (as long as the request returns a valid lookup, naturally!)

[NOTICE] Proxying from 127.0.0.1:54 to 80.90.43.162:5678
You can also monitor /var/log/messages to ensure that unbound started, or at least isn't complaining about one or more of your configuration directives.
To prevent all other outbound DNS queries, a few PF rules might not hurt, but that is, once again, beyond the scope of this unilaterally-focused discussion.
For those who want to round-robin amongst a group of encrypted DNS transports, this is what I've found works well:
Start 6 instances of dnscrypt-proxy, each on lo0 with a unique port:
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:54 -R adamas
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:55 -R opendns
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:56 -R cypherpunk
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:57 -R dnscrypt.org-fr
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:58 -R okturtles
/usr/local/sbin/dnscrypt-proxy -l /dev/null -u _dnscrypt-proxy -d -a 127.0.0.1:59 -R opennic-ca-ns3
Then simply modify your /var/unbound/etc/unbound.conf and list all 6 under the forward-zone as forward-addr you previously configured:
forward-zone:
name: "."
forward-addr: 127.0.0.1@54
forward-addr: 127.0.0.1@55
forward-addr: 127.0.0.1@56
forward-addr: 127.0.0.1@57
forward-addr: 127.0.0.1@58
forward-addr: 127.0.0.1@59
Reload unbound:
/etc/rc.d/unbound -f reload
To confirm, you can tcpdump on ports 443 and 5678 to see which servers are getting distributed hits. This should offer a level of redundancy/reliability to the process, as long as unbound remains running.
Enjoy!
Continued... Since I got a few (ha!) replies to this shortly after posting the previous information, I thought I'd go ahead and wrap up a DNSSEC unbound config while I'm at it.
You'll first need to run /usr/sbin/unbound-anchor, I do it as follows - this MUST be writable by the _unbound user:
# sudo -u _unbound /usr/sbin/unbound-anchor -vvvv -F

success: the anchor has been updated using the cert
This will create /var/unbound/db/root.key. You should probably run unbound-anchor once a week or in /etc/rc.local on every reboot. It's your choice.
Next, modify /var/unbound/etc/unbound.conf and uncomment the following line:
auto-trust-anchor-file: "/db/root.key"
We may as well also grab the latest root.hints file from Internic... You can configure this to pull once a month in root's crontab for good measure.
# ftp -o /var/unbound/db/root.hints "ftp://ftp.internic.net/domain/named.cache"
Place this in your /var/unbound/etc/unbound.conf:
root-hints: "/db/root.hints"
Finally, restart unbound:
# /etc/rc.d/unbound -f restart
To test, dig a few domains. I start with a root and go from there. You're looking for the 'ad' flag as follows:
# dig . SOA +dnssec
; <<>> DiG 9.4.2-P2 <<>> . SOA +dnssec

Ad blocking: Yes, I'll add this soon as well. I've seen so many inept ways to do it that I'd rather take a little more time to make a few scripts I personally use take on a more readable shape.
Where most fail are pointing ad servers DNS records to localhost (do I really need to explain why that doesn't work on a firewall?), force downloads of software or modules /not/ included in the base operating system, or enabling unprotected, unvetted network services to serve the single pixel file, i.e. some socket-based perl/php/python/etc.. script that runs as root from the base system. I'll avoid all that, you should as well.
