我参考了 Spring SAML 手册来创建私钥和导入公共证书。但我仍然面临加密/解密问题。

我已经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 的公共证书的命令

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都定义为“changeit”

我已将 securityContext 配置如下

<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>

我可以看到可以选择 IDP 的 idpDiscovery 页面。我也可以查看 IDP 的登录页面。但是当我提供用户凭据时，我得到了以下异常。

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了？？

替代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，则会收到另一个异常，称为InvalidKeyException: Key is too long for unwrapping。

谁能帮我解决这个问题？？

问题是由于在应用程序中使用的密钥库与使用以下命令生成的密钥库不同：

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