xmldsig | PHP Implementation of XML Digital Signature recomendation

Official answer from Google support: "Google doesn't currently implement Single Log out/account reauthentication, for SAML authorized services. You may alternatively have the use of "session lengths"".

If you take that approach then you would have to declare the namespaces in all extract() clauses, e.g.:

So after a bit more experimenting, I realised that indeed, ippsRSAVerify_PCKS1v15 and RSA_Verify expect different data for their respective pMsg and m arguments. The Intel function wants to be given the entire message to sign/verify, and computes the SHA1 digest (or other digest) internally, whereas the OpenSSL function expects to be given the digest of the message to sign/verify, not the original message itself.

The creation of an XML signature, i.e. the signing of an XML document (XMLDSig), is more complex than the creation of an ordinary signature, since one and the same XML can be serialized differently, i.e. the different serializations are logically identical. Therefore, the XML must be normalized beforehand, i.e. converted into a unique format (Canonicalization). Similarly, the same applies to verification.

.NET largely encapsulates these processes. Thereby, signing is more complex than verifying, since for the latter the parameters (e.g. the canonicalization variant) are contained in the signed XML.
In the signed XML posted in the question, the key (i.e. the certificate) used for verification is already embedded. In this case, a possible implementation of the verification is:

Core does not support Wshttpbinding, wcf only supports BasicHttpBinding, CustomBinding, NetHttpBinding, NetTcpBinding：

I suggest you continue to use the .net framework or modify the server-side binding.

For more information about WCF Features in core, you can refer to this link.

I changed a few things and it started working. Firstly the AsymmetricSecurityBindingElement;

• Set EnableUnsecuredResponse to false.
• Added SecurityHeaderLayout that defaults to "Strict" and set it to "SecurityHeaderLayout.LaxTimestampLast".

Then, I added a custom MessageEncodingBindingElement that implements a custom MessageEncoder. This encoder adds the To and MessageID headers although I do not think this was the problem.

When you create azure app server, the default options of Publish is Code which use sandbox environment.

So the webapp created by default not support Registration-free Com.

But Azure App Service supports Windows Containers, you can customize the container.

You don't want the attribute's namespace, you want the attribute value.

Instead of

You could use an XML Catalog to define where the schema exists locally.

But if you can't do that then you might simply use any URI, according to the spec of to locate and import that schema.

For example, if your schemas are in the same directory then you could do this:
