Obtaining and registering a key
Generating JWT grant
A generator can be downloaded here: https://github.com/felleslosninger/jwt-grant-generator
Then create a JKS store using your company cerfificate (Virksomhetssertifikat, auth cert), you can use KeyStore Explorer for this: https://keystore-explorer.org/downloads.html
Follow instructions in the jwt-grant-generator repo, and create a myclient.properties
file.
Example for production:
issuer=<the client id for your self service client>
# Can be found here:
# https://sjolvbetjening.samarbeid.digdir.no/integrations
audience=https://maskinporten.no/
scope=idporten:dcr.read idporten:dcr.write
keystore.type=JKS
keystore.file=<filename for key store file in JKS format you created eralier>
keystore.password=<key store password>
keystore.alias=<alias in JKS store, called Entry Name in KeyStore Explorer>
keystore.alias.password=<password for alias>
token.endpoint=https://maskinporten.no/token
Then run java -jar target/jwt-grant-generator-1.1.0-SNAPSHOT-jar-with-dependencies.jar myclient.properties
Copy the access_token
from the output, this can be used to read and write to the allowed keys for the DSF client.
Read current and add new jwks keys
client id is the id for your DFS client (typically a uuid).
GET https://integrasjon.difi.no/clients/<clientid>/jwks
Add the access token from the previous step as a Bearer token.
To update/set new keys do a POST to the same endpoint with the ENTIRE key set, so if you want to add a new one and keep the existing one you will need to send both keys in the body.
{ keys:
[
{ key1 (from the GET) },
{ key2 (newly generated public key) }
]
}
A newly uploaded key will be valid for 1 year.
You can generate a key using an online tool like this: https://mkjwk.org/ (Or the offline CLI provided at their GitHub account). The public part is what should be prodived to the jwks endpoint above. While the public+private keypair should be kept secret and is what tibber-dsf should be initialized with (either as JSON or a Base64 encoded string).
Usage
import dsf from 'tibber-dsf';
const queryDsf = dsf({ env: 'prod or test ', clientId: 'the clientId assigned to you in Maskinporten', privateKey: 'a jwk containing the private key registered to your client in maskinporten' })
const result = await queryDsf({ lastName: 'Normann', postalCode: "6812", firstName:'Ola', birthDate : '1977-01-13' });
//To read more about what queries are allowed and which combinations of parameters are required, go to: https://skatteetaten.github.io/folkeregisteret-api-dokumentasjon/oppslag/
//success result
