Wildfly standalone.xml - 从 elytron 凭证存储向 KeyCloak SPI 传递机密信息

我正在将 KeyCloak v15（WildFly v23）密码从旧保险库迁移到 elytron 凭证存储。它对于标准用例来说运行良好。在 中standalone.xml，我有 /server/extensions/extension：：

<extension module="org.wildfly.extension.elytron"/>

/server/profile/subsystem：

<subsystem xmlns="urn:wildfly:elytron:13.0" final-providers="elytron" disallowed-providers="OracleUcrypto">
    <providers>
        <provider-loader name="elytron" module="org.wildfly.security.elytron"/>
    </providers>
    <audit-logging>
        <file-audit-log name="local-audit" path="audit-log.log" relative-to="jboss.server.log.dir" format="JSON"/>
    </audit-logging>
    <credential-stores>
        <credential-store name="credStore" location="/data/credStore.jceks">
            <implementation-properties>
                <property name="keyStoreType" value="JCEKS"/>
            </implementation-properties>
            <credential-reference clear-text="MASK-123456789;salt123;42"/>
        </credential-store>
    </credential-stores>
</subsystem>

我使用以下方法访问密码 /server/profile/subsystem[@xmlns="urn:jboss:domain:jgroups:8.0"]/stacks/stack[@name="tcp"]/auth-protocol/digest-token/shared-secret-reference：

<shared-secret-reference store="credStore" alias="myBlock::mySecret"/>

但是，我需要将一个秘密传递给属性中的 SPI。你知道怎么做吗？这是旧的保险库方式：

/server/system-properties/property：

<property name="secret" value="${VAULT::myBlock::mySecret::1}"/>

/server/profile/subsystem[@xmlns="urn:jboss:domain:keycloak-server:1.1"]/spi：

<spi name="mySpi">
    <provider name="file" enabled="true">
        <properties>
            <property name="password" value="${secret}"/>
        </properties>
    </provider>
</spi>

答案1

我发现了两种可能性：

  1. 重写 SPI 以使用 Java 直接从 Elytron 凭证存储中检索机密
  2. 预先设置一个环境变量（export SECRET="$(secret-getter-script)"）并在以下情况下使用该变量standalone.xml：
<spi name="mySpi">
    <provider name="file" enabled="true">
        <properties>
            <property name="password" value="${env.SECRET}"/>
        </properties>
    </provider>
</spi>

我必须重写我们的 SPI 来读取 Elytron 凭证存储内容：

import org.jboss.as.server.CurrentServiceContainer;
import org.jboss.msc.service.ServiceController;
import org.jboss.msc.service.ServiceName;
import org.jboss.msc.service.ServiceRegistry;
import org.wildfly.security.credential.PasswordCredential;
import org.wildfly.security.credential.store.CredentialStore;
import org.wildfly.security.credential.store.CredentialStoreException;
import org.wildfly.security.password.Password;
import org.wildfly.security.password.interfaces.ClearPassword;

  private static String getClientSecret(String credentialStore, String secretAlias) {
    final ServiceName SERVICE_NAME_CRED_STORE = ServiceName.of("org", "wildfly", "security", "credential-store");
    final ServiceName sn = ServiceName.of(SERVICE_NAME_CRED_STORE, credentialStore);
    final ServiceRegistry registry = CurrentServiceContainer.getServiceContainer();
    final ServiceController<?> credStoreService = registry.getService(sn);
    final CredentialStore cs = (CredentialStore) credStoreService.getValue();
//    if (!cs.exists(secretAlias, PasswordCredential.class)) {
//      throw new CredentialStoreException("Alias " + secretAlias + " not found in credential store.");
//    }
    final Password password;
    try {
      password = cs.retrieve(secretAlias, PasswordCredential.class).getPassword();
    } catch (CredentialStoreException e) {
      e.printStackTrace();
      return null;
    }
    if (!(password instanceof ClearPassword)) {
      throw new ClassCastException("Password is not of type ClearPassword");
    }
    return new String(((ClearPassword) password).getPassword());
  }
