我已經成功部署並運行了spring saml示例。從SAML響應者(IdP - > SP)如下所示,可以將其識別是否:SAML響應和斷言是否已簽名/未簽名?

  1. SAML響應是符號或無符號?
  2. 斷言是否加密? (我猜是加密的)
  3. 斷言是有符號還是無符號?

我從SP服務器的調試日誌,上面的SAML響應被解析之後,如下所示。這使我很困惑,消息和/或斷言是否沒有被簽名。

- Evaluating security policy of type 'org.opensaml.ws.security.provider.BasicSecurityPolicy' for decoded message 
- Evaluating simple signature rule of type: org.opensaml.saml2.binding.security.SAML2HTTPPostSimpleSignRule 
- HTTP request was not signed via simple signature mechanism, skipping 
- SAML protocol message was not signed, skipping XML signature processing 
- Successfully decoded message.

  1. SAML迴應未簽名。
  2. SAML聲明已加密。 (你可以看到「EncryptedAssertion」)
  3. SAML斷言沒有被簽名。

嘗試在您的SP元數據中設置WantAssertionsSigned =「true」,與IdP交換並檢查您是否收到簽名的SAML響應。

參見:http://docs.spring.io/spring-security-saml/docs/current/reference/html/configuration-metadata.html

上IDP改變的配置,現在後的後的反應溶液。但是,這個簽名是否適用於響應和斷言或者只是響應?我如何知道與消息的這種不同? – cole

當設置WantAssertionsSigned =「true」時,收到的簽名對應於斷言部分。嘗試僅簽署收到的斷言部分,並檢查收到的簽名,它必須相同。 – Zeigeist
