Keycloak 身份代理：HMACSHA256 签名不可用
Keycloak Identity Broker: HMACSHA256 Signature not available
我是 运行 docker 中的 Keycloak 15.0.2 (jboss/keycloak:15.0.2) 并使用带有外部 OpenId Connect 身份提供商的身份代理
当在 keycloak 上初始化登录时，浏览器被重定向到外部 IDP。通过身份验证后，浏览器将重定向到 keycloaks 代理端点 /broker/oidc/endpoint?code=xxx
但是 Keycloak 抛出一个由
引起的异常
Caused by: java.security.NoSuchAlgorithmException: HMACSHA256 Signature not available
有人知道为什么会这样吗？ HMACSHA256 算法是否应该已经成为 docker 容器中 JRE 的一部分？

我有同样的问题，可以通过将 Keycloak 中身份提供者的“客户端断言签名算法”从 HS256 更改为 RS256 来解决。
我是 运行 docker 中的 Keycloak 15.0.2 (jboss/keycloak:15.0.2) 并使用带有外部 OpenId Connect 身份提供商的身份代理
当在 keycloak 上初始化登录时，浏览器被重定向到外部 IDP。通过身份验证后，浏览器将重定向到 keycloaks 代理端点 /broker/oidc/endpoint?code=xxx
但是 Keycloak 抛出一个由
引起的异常Caused by: java.security.NoSuchAlgorithmException: HMACSHA256 Signature not available
有人知道为什么会这样吗？ HMACSHA256 算法是否应该已经成为 docker 容器中 JRE 的一部分？
