Spring saml:密钥太长，无法解包:invalidkeyexception [英] Spring saml: Key is too long for unwrapping: invalidkeyexception
本文介绍了Spring saml:密钥太长，无法解包:invalidkeyexception的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的机器上仅安装了一个JDK，并且代码指向相同的JDK.我在两个文件夹(C:\ Program Files \ Java \ jdk1.6.0_25 \ jre \ lib \ security和C:\ Program Files \ Java \ jre6 \ lib \ security)中都安装了强度不受限制的加密库.
I have only one JDK installed in my machine and the code is pointing to the same JDK. I have installed unlimited strength cryptography library in both the folders(C:\Program Files\Java\jdk1.6.0_25\jre\lib\security and C:\Program Files\Java\jre6\lib\security).
即使添加了上述无限强度库，我仍然收到相同的异常.这是其他票证的延续链接
I keep getting the same exception even after adding the above mentioned unlimited strength library. This is in continuation to other ticket link

任何人都可以调查我面临的这个问题并提供解决方案吗?
Can anyone look into this issue which I am facing and provide a solution?
推荐答案
您最有可能尝试使用错误的密钥解密加密的内容.换句话说，IDP可能使用与SP中的私钥不对应的公钥来加密数据.您可以在公共密钥密码学维基百科文章中找到有关这些概念的详细信息.
You are most likely trying to decrypt the encrypted content with wrong key. In other words, IDP is likely encrypting data with a public key which does not correspond to the private key in your SP. You can find details on these concepts in public key cryptography wikipedia article.
一旦为服务提供商实例(= Spring SAML安装)生成了私钥+公钥+证书，则必须将生成的公钥提供给IDP.通常，这是通过创建描述您的SP的元数据文档(默认情况下会自动生成，从scheme://host:port/appcontext/saml/metadata，例如http://localhost:8080/spring_saml/saml/metadata下载)并将其提供给IDP来完成的.元数据文档包含带有SP的X509证书和公共密钥，IDP使用该元数据对发送到SP的数据进行加密.
Once you generate private key + public key + certificate for your Service Provider instance (= Spring SAML installation), you must provide the generated public key to your IDP. This is typically done by creating metadata document describing your SP (which is by default auto-generated, download it from scheme://host:port/appcontext/saml/metadata, e.g. http://localhost:8080/spring_saml/saml/metadata) and providing it to the IDP. The metadata document contains the X509 certificate with public key for your SP and is used by IDP to encrypt data sent to your SP.
