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.

    Table 1. Response Codes
    Code Description

    200

    The request was successful. 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

    URI

    PUT /api/key/{keyId}

    Request Parameters

    keyId [UUID] Required

    The unique Id of the Key to update.

    Request Body

    key.name [String] Required

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

    Example Request JSON

    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
