SAML 未能验证签名

Question

我正在使用PySaml2 来实现一个 SAML 服务提供者。

当我收到有效负载 (base64 SAMLResponse) 时，我的服务器无法接受它并出现错误 SignatureError('Failed to verify signature')。

失败的部分是对 XMLSec 库的调用：xmlsec1 --verify --enabled-reference-uris empty,same-doc --enabled-key-data raw-x509-cert --pubkey-cert-pem /path/to/cert.pem --id-attr:ID urn:oasis:names:tc:SAML:2.0:assertion:Assertion --node-id ... --output /path/to/out.xml /path/to/payload.xml。

但是，我使用的是 IdP 发送给我的证书，我可以在传递给上述调用的 cert.pem 中看到它确实是传递给 xmlsec1 的正确证书（与有效载荷本身）。

Answer 1

这很难调试，因为您发布的 XML 不包含证书、摘要并且已修改。

XML 在发布到网站时可能很难检查。修改后是不可能的。请从测试系统生成另一个文件并再次发送。在附加之前先对其进行 Base64 编码也很好。

您也可以尝试 --trusted-pem /path/to/cert.pem 选项

更新：

使用新的 base64

使用https://samltool.io/ 表明响应已签名而不是断言，因此以下将起作用：

xmlsec1 --verify --trusted-pem cert.pem --enabled-reference-uris empty,same-doc --enabled-key-data raw-x509-cert --pubkey-cert-pem cert.pem - -id-attr:ID 响应 --output out.xml tmp.xml

这也适用于 XML::Sig 和 https://tools.chilkat.io/xmlDsigVerify.cshtml

我没有使用 PySaml2，所以它可能有错误，但如果没有，它现在应该使用正确的证书来验证
