xmlsec无法验证签名

我试图用xmlsec1实用程序验证 XML(附在问题的底部)签名.但是,在执行命令时

xmlsec1 --verify test.xml

我正在跟踪堆栈跟踪：

“`

基于堆栈跟踪,我认为ID有问题.经过一番挖掘,我发现了执行

xmlsec1 --verify --id-attr:ID 
"urn:oasis:names:tc:SAML:2.0:protocol:Response" test.xml

产生以下堆栈跟踪

func=xmlSecopenSSLEvpDigestVerify:file=digests.c:line=249:obj=sha1:subj=unkNown:error=12:invalid data:data and digest do not match
FAIL
SignedInfo References (ok/all): 0/1
Manifests References (ok/all): 0/0
Error: Failed to verify file “test.xml”

这是test.xml文件的修剪内容：

你能解释一下我在这里做错了什么吗？如何使用xmlsec验证签名的XML文件？

解决方法

我找到了一种正确的方法来验证这一点,所以这里是如何：

首先,必须指定ID属性：

xmlsec1 –verify –id-attr：ID
“urn：oasis：names：tc：SAML：2.0：protocol：Response”test.xml

对我的XML文件执行此命令导致错误无效数据：数据和摘要不匹配.

我一直在针对格式化XML的SAML Tracer(Firefox插件)返回的输出调用此命令 – 这会更改签名,因此xmlsec1会输出错误.

对原始(解密)内容调用xmlsec1工作正常.
