Question

我已提及Spring SAML手册来创建私钥并导入公共证书。但我仍然面临加密/解密问题。

我使用手册中提到的以下命令创建了一个JKS文件，如下所示

用于导入IDP公共证书的命令

keytool -importcert -alias adfssigning -keystore samlKeystore.jks -file testIdp.cer

用于私钥的命令

keytool -genkeypair -alias myprivatealias -keypass changeit -keystore samlKeystore.jks

私钥和密钥库的密码定义为＆＃39; changeit＆＃39;

我已经按如下方式配置了securityContext

<bean id="keyManager" class="org.springframework.security.saml.key.JKSKeyManager">
    <constructor-arg value="classpath:security/samlKeystore.jks"/>
    <constructor-arg type="java.lang.String" value="changeit"/>
    <constructor-arg>
        <map>
            <entry key="myprivatealias" value="changeit"/>
        </map>
    </constructor-arg>
    <constructor-arg type="java.lang.String" value="myprivatealias"/>
</bean>

我可以看到idpDiscovery页面，我可以在其中选择IDP。我也可以查看IDP的登录页面。但是，当我提供用户凭据时，我收到以下异常。

当saml2：EncryptedAssertion与SAML响应中的saml2p：Status一起发送时，会发生此异常。（类：Spring-saml jar的WebSSOProfileConsumerImpl）

谁能让我知道我哪里出错？

备用命令使用私钥生成而不是上面提到的

keytool -genkey -alias privatekeyalias -keyalg RSA -keystore samlKeystore.jks

如果我使用此命令并更新JKS文件，那么我会得到一个不同的异常，因为 InvalidKeyException：Key太长而无法展开。

任何人都可以帮我解决这个问题吗？

Answer 1

问题是由于在应用程序中使用不同的密钥库而不是使用：

生成的密钥库

keytool -genkeypair -alias privatekeyalias -keypass samplePrivateKeyPass -keystore samlKeystore.jks -keyalg RSA -sigalg SHA1WithRSA

Spring SAML：解密加密密钥时出错，没有安装的提供程序支持此密钥
