Adds new JSON Web key (JWK)#

To add a new key, we can use post-config-jwks-key operation id. As shown in the output for --info command, the post-config-jwks-key operation requires data to be sent according to JSONWebKey schema.

To see the schema, use the command below:

Command
jans cli --schema JSONWebKey
The Janssen Server also provides an example of data that adheres to the above schema. To fetch the example, use the command below.

Command
jans cli --schema-sample JSONWebKey
Using the schema and the example above, we have added below key data to the file /tmp/jwk.json.

Now let's post this key to the Janssen Server to be added to the existing set:

Command
jans cli --operation-id post-config-jwks-key --data /tmp/jwk.json

Replace JSON Web Key Set#

To replace the current JWKS configuration, use the put-config-jwks operation. This operation replaces the current set of JWK with the provided set.

 Operation ID: put-config-jwks
 Description: Replaces JSON Web Keys
 Schema: WebKeysConfiguration

To get the schema file:

Command
 jans cli --schema WebKeysConfiguration

As suggested in the schema, we have to provide an array of keys in a json file containing key-value pairs. The properties in the key are defined by the JWK specification RFC 7517, and for algorithm-specific properties, in RFC 7518.

Properties#

name Description
kid It's a unique identifier for the key configuration.
kty It's used to define the type of the specific cryptographic algorithms
use This parameter identifies the intended use of the public key. sig for signature and enc for encryption
alg The specific algorithm used with the key
crv
exp The exponent for the RSA public key.
x5c The x5c parameter contains a chain of one or more PKIX certificates RFC5280
n The modulus for the RSA public key.
e The "e" (exponent) parameter contains the exponent value for the RSA public key. It is represented as a Base64urlUInt-encoded value.
x The "x" (x coordinate) parameter contains the x coordinate for the Elliptic Curve point.
y The "y" (y coordinate) parameter contains the y coordinate for the Elliptic Curve point.

Let's update the json file to create a new key configuration.

Now let's put the new keys into the Janssen server.

Command
 jans cli --operation-id put-config-jwks --data /tmp/path-jwk.json

Please remember that this operation replaces all JWKs in the Janssen server with new ones. So, in this case, if you want to keep old JWKs, you have to put them as well in the input file.

Get a JSON Web Key Based on kid#

With get-jwk-by-kid operation-id, we can get any specific jwk matched with kid. If we know the kid, we can simply use the below command:

Command
jans cli --operation-id get-jwk/janssen-server/config-guide/auth-server-config/json-web-key-config-by-kid \
--url-suffix kid:dd550214-7969-41b9-b919-2a0cfa36047b_enc_rsa1_5

It returns the details as below:

Patch JSON Web Key (JWK) by kid#

Using patch-config-jwks operation, we can modify JSON Web Keys partially for its properties.

Operation ID: patch-config-jwks
 Description: Patches JSON Web Keys
 Schema: Array of JsonPatch

To use this operation, specify the id of the key that needs to be updated using the --url-suffix and the property and the new value using the JSON Patch . Refer here to know more about schema.

In this example; We will change the value of the property use from enc to sig.

Input
[
{
  "op": "replace",
  "path": "use",
  "value": "sig"
}
]

Now let's do the operation with the command line.

Command
jans cli --operation-id patch-config-jwk-kid \
--url-suffix kid:dd550214-7969-41b9-b919-2a0cfa36047b_enc_rsa1_5 --data /tmp/schema.json

Updated Json Web Key:

We see it has replaced the value of the use property from enc to sig.

Please read about patch method, You can get some idea of how this patch method works to modify particular properties of any task.

Delete Json Web Key using kid#

It's pretty simple to delete json web key using its kid. The command line is:

Command
jans cli --operation-id delete-config-jwk-kid \
--url-suffix kid:dd550214-7969-41b9-b919-2a0cfa36047b_enc_rsa1_5

It will delete the jwk if it matches with the given kid.

Using Text-based UI#

In Janssen, you can view the JSON web keys using the Text-Based UI also.

You can start TUI using the command below:

Command
jans tui

JSON Web Key (JWK) Screen#

Navigate to Auth Server -> Keys to open the JSON Web Key screen as shown in the image below.

  • After clicking on Get keys, You can view Key's list on this page. You cannot perform any operations in text-based UI.

  • Only you can perform operations using the command line.
