Keys

Overview

This API has been available since 1.6.0

Cryptographic keys are used in signing and verifying JWTs and verifying responses for third party identity providers. It is more likely you will interact with keys using the FusionAuth UI in the Key Master menu. If you do have a need to retrieve or manage keys using the API the following APIs have been provided.

Retrieve a Key

This API is used to retrieve a single Key by unique Id or all of the configured Keys.

Request

Retrieve all of the Keys

GET /api/key

Retrieve a Key by Id

GET /api/key/{keyId}

Request Parameters

keyIdUUIDrequired

The unique Id of the Key to retrieve.

Response

The response for this API contains either a single Key or all of the Keys. When you call this API with an Id the response will contain a single Key. When you call this API without an Id the response will contain all of the Keys. Both response types are defined below along with an example JSON response.

Response Codes

Code	Description
200	The request was successful. The response will contain a JSON body.
400	The request was invalid and/or malformed. The response will contain an Errors JSON Object with the specific errors. This status will also be returned if a paid FusionAuth license is required and is not present.
401	You did not supply a valid Authorization header. The header was omitted or your API key was not valid. The response will be empty. See Authentication.
404	The object you requested doesn't exist. The response will be empty.
500	There was an internal error. A stack trace is provided and logged in the FusionAuth log files. The response will be empty.
503	The search index is not available or encountered an exception so the request cannot be completed. The response will contain a JSON body.

Update a Key

This API method is used to update an existing Key.

Only the name of the Key may be changed; all other fields will remain the same. If you need to update a Key with a new certificate, algorithm or other attributes, please Import a Key.

For example, if you have a Key with an associated expiring certificate, you’ll need to follow the steps similar to those outlined in the JWT signing key rotation documentation:

Import this key, keypair or certificate into FusionAuth. This will create a new Key entity in FusionAuth.
Update the appropriate configuration with this new Key (JWT signing configuration, SAML validation configuration, etc).
Once the new Key is configured for use, remove the expired, previous Key.

Note that validation rules will prevent you from removing an in-use key.

Update the Key with the given Id

PUT /api/key/{keyId}

Request Parameters

keyIdUUIDrequired

The unique Id of the Key to update.

Request Body

key.nameStringrequired

The name of the Key. It must be unique among all Keys.

Example Request JSON

{
  "key": {
    "name": "OpenID Connect compliant HMAC using SHA-256"
  }
}

Search for Keys

This API has been available since 1.45.0

This API is used to search for Keys and may be called using the GET or POST HTTP methods. Examples of each are provided below. The POST method is provided to allow for a richer request object without worrying about exceeding the maximum length of a URL. Calling this API with either the GET or POST HTTP method will provide the same search results given the same query parameters.

Request

Search for Keys

GET /api/key/search?algorithm=RS256&name={name}&type=RSA

Request Parameters

algorithmString

The algorithm used to generate the key.

The possible values are:

ES256 - ECDSA using P-256 curve and SHA-256 hash algorithm
ES384 - ECDSA using P-384 curve and SHA-384 hash algorithm
ES512 - ECDSA using P-521 curve and SHA-512 hash algorithm

HS512 - HMAC using SHA-512 hash algorithm

nameString

The case-insensitive string to search for in the Key name. This can contain wildcards using the asterisk character (*). If no wildcards are present, the search criteria will be interpreted as *value*.

numberOfResultsIntegerDefaults to 25

The number of results to return from the search.

orderByStringDefaults to name ASC

The field to order the search results as well as an order direction.

The possible values are:

algorithm - the algorithm used to generate the Key. ** Not all keys have an algorithm, null values are treated as smaller than all other values. ** The possible values are: See algorithm .
expiration - the expiration instant of the Key. ** Not all keys have an expiration value, null values are treated as smaller than all other values.
id - the UUID of the Key
insertInstant - the instant when the Key was created
name - the Key name
type - the Key type ** The possible values are: See type .

The order direction is optional. Possible values of the order direction are ASC or DESC. If omitted, the default sort order is ASC.

For example, to order the results by the insert instant in a descending order, use insertInstant DESC.

startRowIntegerDefaults to 0

The offset into the total results. In order to paginate the results, increment this value by the numberOfResults for subsequent requests.

For example, if the total search results are greater than the page size designated by numberOfResults , set this value to 25 to retrieve results 26-50, assuming the default page size.

typeString

The key type. The possible values are:

EC
RSA
HMAC

This API is used to import an existing Key into FusionAuth.

For RSA pairs, possible key lengths are: 1024 (only valid when importing a public key for signature verification), 2048, 3072 or 4096.

For EC pairs, possible key lengths are: 256, 384, or 521.

Import an existing Key with a randomly generated Id

POST /api/key/import

Import an existing Key with the provided unique Id

POST /api/key/import/{keyId}

Request Parameters

keyIdUUID

The unique Id of the Key. Use if you want to specify a known UUID. This is useful if you are migrating from an existing system or will otherwise depend on having a known key Id.

Request Body

key.algorithmString

The algorithm used to generate the Key. The algorithm will be inferred if it is not passed explicitly. The following values represent algorithms supported by FusionAuth:

ES256 - ECDSA using P-256 curve and SHA-256 hash algorithm
ES384 - ECDSA using P-384 curve and SHA-384 hash algorithm
ES512 - ECDSA using P-521 curve and SHA-512 hash algorithm
RS256 - RSA using SHA-256 hash algorithm
RS384 - RSA using SHA-384 hash algorithm
RS512 - RSA using SHA-512 hash algorithm
HS256 - HMAC using SHA-256 hash algorithm
HS384 - HMAC using SHA-384 hash algorithm
HS512 - HMAC using SHA-512 hash algorithm

key.certificateString

The certificate to import. The publicKey will be extracted from the certificate.

key.kidString

The Key identifier ‘kid’. When this value is omitted, one will be generated.

key.nameStringrequired

The name of the Key. It must be unique among all Keys.

key.publicKeyString

The Key public key. Required if importing an RSA or EC key and a certificate is not provided.

key.privateKeyString

The Key private key. Optional if importing an RSA or EC key. If the key is only to be used for token validation, only a public key is necessary and this field may be omitted.

key.secretString

The Key secret. This field is required if importing an HMAC key type.

key.typeString

The Key type. This field is required if importing an HMAC key type, or if importing a public key / private key pair. The possible values are:

EC
RSA
HMAC

Response

The response for this API contains the Key that was imported.

Response Codes

Code	Description
200	The request was successful. The response will contain a JSON body.
400	The request was invalid and/or malformed. The response will contain an Errors JSON Object with the specific errors. This status will also be returned if a paid FusionAuth license is required and is not present.
401	You did not supply a valid Authorization header. The header was omitted or your API key was not valid. The response will be empty. See Authentication.
500	There was an internal error. A stack trace is provided and logged in the FusionAuth log files. The response will be empty.
503	The search index is not available or encountered an exception so the request cannot be completed. The response will contain a JSON body.

Response Body
