Key store set up
create the client keystore with the client certificate
openssl pkcs12 -export -in /srv/certs/selfsigned/cert.pem -inkey /srv/certs/selfsigned/key-nopass.pem -out certs.p12 -name client
keytool -importkeystore -deststorepass password -destkeypass password -destkeystore keystore.jks -srckeystore certs.p12 -srcstoretype PKCS12 -srcstorepass password -alias client
add the director ca to the keystore
keytool -import -file auth1.pem -keystore keystore.jks
Admin tool set up
specify the follwing configuration parameters in the admin tool, at <app_root>/admin/admin.py
# set configuration parameters
datastore = '/tmp/agora_elections/datastore'
shared_secret = 'hohoho'
db_user = 'agora_elections'
db_password = 'agora_elections'
db_name = 'agora_elections'
app_host = 'localhost'
app_port = 9000
node = '/usr/local/bin/node'
set the executable permissions if not already set for several admin scripts
chmod u+x admin.py
chmod u+x cycle.py
chmod u+x batch.py
chmod u+x encrypt.sh
chmod u+x results.sh
Create a virtualenv for the admin script and install admin script requirements:
mkvirtualenv agora_elections -p $(which python2)
workon agora_elections
cd agora_elections/admin
pip install -r requirements.txt
Agora-Results set up
Clone and install agora-results
git clone https://github.com/agoravoting/agora-results.git
mkvirtualenv agora-results -p $(which python3)
workon agora-results
cd agora-results
pip install -r requirements.txt
you must also configure these two settings in results.sh, found in agora-elections/admin
AGORA_RESULTS=/tmp/agora-results
VENV=/root/.virtualenvs
Local vote encryption set up
If you want to encrypt votes locally (for testing purposes, see below), you must configure these settings in admin/encrypt.sh
IVY=/root/.ivy2/cache/
you must also make sure that the software is packaged from the activator console, with
[agora-elections] $ package
which will generate the required jar in the target directory (note that encrypt.sh assumes scala v2.11)
Postgresql parameters
Some tuning changes can be made in /etc/postgresql//main/postgresql.conf
max_connections = 200
checkpoint_segments = 16
checkpoint_completion_target = 0.7
restart the server
service restart postgresql
You can run units tests with
activator
test
Note that for tests to pass the datastore directory structure specified in test.local.conf must exist and be writable.
An election cycle can be run with the admin.py tool in the admin directory
You must first create an election config json file. Here's an example
{
"id": 66,
"title": "My vote",
"description": "choose stuff",
"director": "my_director",
"authorities": ["my_authority"],
"layout": "pcandidates-election",
"presentation": {
"share_text": "share this",
"theme": "foo",
"urls": [
{
"title": "",
"url": ""
}
],
"theme_css": "whatever"
},
"end_date": "2013-12-09T18:17:14.457000",
"start_date": "2013-12-06T18:17:14.457000",
"questions": [
{
"description": "",
"layout": "pcandidates-election",
"max": 1,
"min": 0,
"num_winners": 1,
"title": "My question",
"extra_options": {
"shuffle_categories": true,
"shuffle_all_options": true,
"shuffle_category_list": []
}
"tally_type": "plurality-at-large",
"answer_total_votes_percentage": "over-total-valid-votes",
"answers": [
{
"id": 0,
"category": "Cat A",
"details": "",
"sort_order": 1,
"urls": [
{
"title": "",
"url": ""
}
],
"text": "Option A"
},
{
"id": 1,
"category": "Cat B",
"details": "",
"sort_order": 1,
"urls": [
{
"title": "",
"url": ""
}
],
"text": "Option B"
}
]
}
]
}
Register the election (config must be named 50.json here)
./admin.py register 50
create the election
./admin.py create 50
dump the pks
./admin.py dump_pks 50
encrypt votes (normally only used for testing; you need an votes.json file to do this)
./admin.py encrypt 50
start the election
./admin.py start 50
cast votes (normally only used for testing, votes are generated with encrypt)
./admin cast_votes 50
stop the election
./admin.py stop 50
tally the election
./admin.py tally 50
calculate results
./admin results 50 --results-config config.json
publish results
./admin.py publish_results 50
You can also carry out administration commands in batch mode, with batch.py. batch.py expects a directory with configuration files for both election definition and agora-results set up. The files must be in this format
<id>.results.json
for election configuration files, and
<id>.config.results.json
for agora-results configuration files. batch.py will run the command for all the configuration files found in the given directory, in increasing order of id. For example
./batch.py -c create -d json_files
will register, create and start elections for all configuration files in directory 'json_files'. If you only want to operate on a range, you can use this form
./batch.py -c create -d json_files -s 1000 -e 2000
which will create elections with id beginning with 1000 up to 2000 (both inclusive)
You can do automated tests with the cycle.py tool in the admin directory. This requires correctly setting up admin.py first, as described earlier. You need an election configuration as base, you can use one like the one above. cycle.py looks for such a file with default name 'election.json'. You also need an agora-results configuration file to calculate results. cycle.py looks for such a file at 'config.json'. Here's an example agora-results configuration file
[
[
"agora_results.pipes.results.do_tallies",
{"ignore_invalid_votes": true}
],
[
"agora_results.pipes.results.to_files",
{"paths": ["results.json"]}
]
]
To run 5 cycles serially, starting with id 50
./cycle.py -t 5 -i 50
to run 5 cycles serially, casting 100 votes in each (votes duplicated)
./cycle.py -t 5 -i 50 -e 100
to run 10 cycles in parallel, using election.json as election config, config.json as agora-results config, casting 100 votes and starting at id 50:
./cycle.py -t 10 -i 50 -e 100 -c election.json -r config.json -p
You can cast test votes into the ballotbox with the following steps. First, edit the encrypt.sh file and specify the correct value for variables
IVY=/root/.ivy2/cache
AGORA_HOME=..
In order to cast votes for an election, that election must be in the correct state, which is 'started'. This state implies the existence of public keys with which to encrypt votes, and also that the ballotbox will accept incoming votes. Casting votes is done in three steps, first dump the public keys
./admin.py dump_pks <election_id>
then encrypt some votes
./admin.py encrypt <election_id>
This command will look for plaintexts in the file 'votes.json' in the same directory, otherwise override with
./admin.py encrypt <election_id> --plaintexts myvotes.json
The votes.json file must be in json array following format, for example to encrypt the values '1' and '2'
[1, 2]
Once this command completes it will have placed a file 'ciphertexts_electionid' in the same directory. To cast the ciphertexts into the ballotbox run
./admin.py cast_votes <election_id>
which will automatically look for the ciphertexts file generated above in the same directory. You can override this location in both commands with the '--ciphertexts' switch.

you probably want to pass in a configuration file
target/universal/stage/bin/agora-elections -Dconfig.file=/full/path/to/conf/application-prod.conf
the log will be found in
