The keystore `adservices_untrusted_test_server.p12` has been generated with the following commands
and using the password `adservices_test`.
The cert file `adservices_untrusted_test_server.crt` is then NOT copied under `res/raw` to use for
testing localhost support on user-builds.

```shell
openssl req -new -x509 -nodes -sha1 -days 3650 \
    -subj "/CN=AdServicesTests" \
    -addext "subjectAltName=DNS:localhost,IP:127.0.0.1" \
    -out /tmp/adservices_untrusted_test_server.crt \
    -keyout /tmp/adservices_untrusted_test_server.key
```

Generate P12 with passcode: `adservices_test`
```shell
openssl pkcs12 -export -keypbe pbeWithSHA1And3-KeyTripleDES-CBC \
-certpbe pbeWithSHA1And3-KeyTripleDES-CBC  -macalg sha1 \
-in /tmp/adservices_untrusted_test_server.crt -inkey /tmp/adservices_untrusted_test_server.key \
-out adservices_untrusted_test_server.p12
```
