Key Master

    Overview

    Signing keys and certificates are managed in FusionAuth using Key Master. After creating or importing a key, use it with other FusionAuth functionality, such as signing JSON Web Tokens or SAML Requests. This page describes the Admin UI for creating and managing signing keys.

    You can also manage keys via the Keys API. You may also be interested in rotating your keys.

    Create or Manage Keys

    Navigate to Settings → Key Master. Here you will see a list of keys and certificates.

    The default Key Master listing.

    From this page, you can add and import keys and certificates as well as view and remove keys. There are certain default keys that you cannot remove. See the FusionAuth limitations for more.

    Select the operation from the menu on the listing page.

    Importing vs Generating

    You can import keys and certificates. This is useful if you are integrating with an external system. For instance, you may be migrating from another auth system and want to import keys generated by that auth system to ensure anything signed with those keys will continue to work.

    You can generate keys as well. This is useful when FusionAuth is your system of record for such keys.

    Import RSA Key Pair

    Import a RSA key pair.

    Form Fields

    Id Optional

    When this value is omitted, a unique Id will be generated automatically.

    Name Required

    The name of the Key. This must be unique.

    Key Identifier Optional

    The Key identifier. This is used in JWT metadata and, if applicable, the JWKS endpoint, as the kid value. When this value is omitted, one will be generated.

    Algorithm Required

    The particular RSA algorithm used to generate the Key.

    Public key Required

    The PEM encoded public key to import.

    Private key Optional

    The PEM encoded private key to import. If the key is to be used for token validation only, this field may be omitted as only a public key is necessary.
