This is a reference implementation of the FDO v1.1 Proposed Standard published by the FIDO Alliance. It provides production-ready implementation for the protocol defined by the specification. It also provides example implementation for different components to demonstrate end-to-end execution of the protocol. Appropriate security measures should be taken while deploying the example implementation for these components.

NOTE: FDO service require strong random number generation in order to perform the required cryptographic functions. The FDO servers will hang on startup waiting for sufficient entropy unless the system continuously supplied random data.
sudo apt-get install -y haveged
will ensure the system fdo services are running on have sufficient entropy.
For the instructions in this document, <fdo-pri-src>
refers to the path of the FDO PRI folder 'pri-fidoiot'.
FDO PRI source code is organized into the following sub-folders.
-
component-samples
: It contains all the normative and non-normative server and client implementation with all specifications listed in the base profile. -
protocol
: It contains implementations related to protocol message processing.
FDO PRI source is written in Java 17 and uses the Apache Maven* software.
The list of ports that are used for unit tests and sample code:
Port | Description |
---|---|
8038 | manufacturer https port |
8039 | manufacturer http port |
8040 | rv http port |
8041 | rv https port |
8042 | owner http port |
8043 | owner https port |
3306 | PRI Service Database port |
8070 | reseller http port |
8072 | reseller https port |
8080 | aio http port |
8082 | aio H2 Console port |
8083 | manufacturer H2 Console port |
8084 | rv H2 Console port |
8085 | owner H2 Console port |
8073 | reseller H2 Console port |
8443 | aio https port |
Use the following commands to build FDO PRI source.
$ cd <fdo-pri-src>
$ mvn clean install
or FDO PRI source can be built using docker container. REFER
The build creates artifacts which will be used in the rest of this guide.
The runnable artifacts can be found in <fdo-pri-src>/component-samples/demo/
.
NOTE: Export the following variable JDK_JAVA_OPTIONS="--add-opens java.base/java.lang=ALL-UNNAMED"
, if you are facing ClassFormatError exception while building using maven.
NOTE: If build is taking a lot of time in RHEL*, check the entropy of machine using cat /proc/sys/kernel/random/entropy_avail
and make sure it's a multiple of 1000. If it's not a multiple of 1000, then run the following commands: sudo yum install rng-tools -y
and sudo service rngd start
.
NOTE: Before starting the container on an open network, ensure that all the proxy settings are disabled, if any, and then proceed with starting the container.
Credentials are defined in the <fdo-pri-src>/component-samples/demo/{component}/service.env
for each service and will be made available as environment variables to each docker/podman container.
aio/service.env manufacturer/service.env owner/service.env reseller/service.env rv/service.env
The following passwords are defined in each service.env:
Environment Variable | Description |
---|---|
db_user | database user account. |
db_password | database password |
api_password | defines the DIGEST REST API password |
encrypt_password | keystore encryption password |
ssl_password | Https/web server keystore password |
user-cert | File containing Client keypair (mTLS) |
ssl-ca | File containing the CA certificate of Server (mTLS) |
api_user | Field containing Client's certificate details (mTLS) |
useSSL | Boolean value specifying SSL connection with Database |
requireSSL | Boolean value specifying SSL connection with Hibernate ORM |
Keystores containing private keys can be stored in the database - <fdo-pri-src>/component-samples/demo/{component}/app-data/emdb.mv.db
as well as in the mounted file system. During runtime, the deployer can decide the mode of Keystore IO by activating the required worker class.
keys_gen.sh can be used to generate random passwords for each service.env.
NOTE: Changing the database password after the H2 database has been created requires the database file to be deleted and recreated.

Generating demo certificate authority KeyPair and certificate
cd <fdo-pri-src>/component-samples/demo/scripts bash demo_ca.sh
NOTE: Configure the properties of
demo-CA
by updatingroot-ca.conf
. -
Generating Server and Client Keypair and certificates.
cd <fdo-pri-src>/component-samples/demo/scripts bash web_csr_req.sh bash user_csr_req.sh
NOTE: Both Server and Client certificates are signed by the previously generated demo-CA. Moreover, we can configure the properties of Server and Client certificates by updating
web-server.conf
andclient.conf
respectively. Learn how to configure Server and Client Certificates. -
Running keys_gen.sh will generate random passwords for the all http servers and creates
secrets
folder containing all the required.pem
files of Client, CA and Server component.$ cd <fdo-pri-src>/component-samples/demo/scripts $ ./keys_gen.sh
A message "Key generation completed." will be displayed on the console.
Credentials will be stored in the
secrets
directory within<fdo-pri-src>/component-samples/demo/scripts
.NOTE: Execute the following command to add hosted rendezvous certificates to the java client trust stores.
$ echo | openssl s_client -proxy ${https_proxy_host}:${https_proxy_port} -showcerts -connect fdorv.com:443 2>/dev/null | sed -n '/-----BEGIN CERTIFICATE-----/, /-----END CERTIFICATE-----/p' >> ./secrets/ca-cert.pem
-
Copy both
secrets/
andservice.env
file from<fdo-pri-src>/component-samples/demo/scripts
folder to the individual components.NOTE: Don't replace
service.env
present in the database component with generatedservice.env
inscripts
folder.$ cd <fdo-pri-src>/component-samples/demo/scripts $ cp -r ./secrets/. ../<component> $ cp service.env ../<component>
NOTE: Component refers to the individual FDO services like aio, manufacturer, rv , owner and reseller.
NOTE: Docker secrets are only available to swarm services, not to standalone containers. To use this feature, consider adapting your container to run as a service. Stateful containers can typically run with a scale of 1 without changing the container code.
NOTE: Make sure to clean
api-user.pem
of the owner component at<fdo-pri-src>/component-samples/demo/owner/secrets/
and restart owner service, if connections to the external Rendezvous service are failing. With certificates present inapi-user.pem
the owner component tries to perform an mTLS connection with the external Rendezvous component.
When the http server starts for the first time it will generate a self-signed certificate for https protocol.
The subject name of the self-signed certificate is defined in the web-server.conf
and client.conf
.
Uncomment subjectAltName
and allowed list of IP and DNS in [alt_names]
section. Example:
#[ req_ext ]
subjectAltName = @alt_names
[ alt_names ]
#Replace or add new DNS and IP entries with the ones required by the HTTPs/Web Service.
DNS.1 = www.example.com
DNS.2 = test.example.com
DNS.3 = mail.example.com
DNS.4 = www.example.net
IP.1 = 127.0.0.1
IP.2 = 200.200.200.200
IP.3 = 2001:DB8::1
NOTE: Self-signed certificates created using the script is not recommended for use in production environments.

Start the Database service
cd <fdo-pri-src>/component-samples/demo/db
docker-compose up --build -d/ podman-compose up --build -d
NOTE: By default, Database uses mTLS connection for jdbc. MariaDB* is used as the default database. For non-mTLS jdbc connection, set use_ssl
and require_ssl
property to false
in service.yml
of individual services.
NOTE: Follow the steps to Enable embedded H2 database
To start the server as a docker/podman container.

$ docker-compose up --build -d/ podman-compose up --build -d
To start the server as a standalone java application.
$ cd <fdo-pri-src>/component-samples/demo/manufacturer
$ java -jar aio.jar
The server will listen for FDO PRI HTTP & HTTPS messages on port 8039 and 8038 respectively.
NOTE: By default the device is configured to run with the All-In-One (AIO) ports. You must edit the service.yml in the demo device directory to run with the manufacturer demo.
$ cd <fdo-pri-src>/component-samples/demo/device
$ docker-compose up --build -d
To start the Client as a standalone java application.
$ cd <fdo-pri-src>/component-samples/demo/device
$ java -jar device.jar
Running the device for the first time will result in device keys being generated and the device keys are stored in the app-data
directory.
Once device keys are generated the device will run the DI protocol and store the DI credentials in a file called credentials.bin
.
Running device for a second time will result in the device performing TO1/TO2 protocols.
Deleting the credentials.bin
file will force the device to re-run DI protocol.
<fdo-pri-src>/component-samples/demo/device/service.yml
contains the configuration of the device.
Before running the device for the first time start the demo aio server.
Run the demo device
As auto injection of ownership voucher is enabled in AIO by default; the ownership voucher is extended and stored in ONBOARDING_CONFIG
table and the device is ready for TO1/2.
