Keys APIs

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

URI

GET/api/key
Retrieve a Key by Id

URI

GET/api/key/{keyId}

Request Parameters

keyId[UUID]required

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.

CodeDescription
200The 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.
503The search index is not available or encountered an exception so the request cannot be completed. The response will contain a JSON body.

Response 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:

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

This API does not return a JSON response body.

CodeDescription
200The 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.

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

URI

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

Request Parameters

truealgorithm[String]optional

The algorithm used to generate the key.

The possible values are:

  • ES256 - ECDSA using P-256 curve and SHA-256 hash algorithm

  • HS384 - HMAC using SHA-384 hash algorithm
  • HS512 - HMAC using SHA-512 hash algorithm
truename[String]optional

truenumberOfResults[Integer]optionalDefaults to 25

The number of results to return from the search.

trueorderBy[String]optionalDefaults to name ASC

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

The possible values are:

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

truestartRow[Integer]optionalDefaults 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.

truetype[String]optional

The key type. The possible values are:

  • EC

Import a Key

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

URI

POST/api/key/import
Import an existing Key with the provided unique Id

URI

POST/api/key/import/{keyId}

Request Parameters

keyId[UUID]optional

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.algorithm[String]optional

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.certificate[String]optional

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

key.kid[String]optional

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

key.name[String]required

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

key.publicKey[String]optional

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

key.privateKey[String]optional

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.secret[String]optional

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

key.type[String]optional

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
CodeDescription
200The 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.
503The search index is not available or encountered an exception so the request cannot be completed. The response will contain a JSON body.
