- `PS512` - RSASSA-PSS using SHA-512

  &#xA;&#xA;RSASSA-PSS signing algorithms require a Java 8 or Java 11 runtime environment, or an integration with a hardware security module (HSM) and a static-key configuration for OAuth and OpenID Connect. For more information on HSM integration and static keys, see Supported hardware security modules and Keys for OAuth and OpenID Connect, respectively.When this parameter is not provided, the client can use any of the supported signing algorithms.For more information about request objects, see [RFC 9101: JWT Secured Authorization Request (JAR)](https://datatracker.ietf.org/doc/rfc9101/).                                                                                                                                                                                                                                                                                                                                                                                                                                                      |
