when a saml document needs to prove the integrity of part of the content of that document it uses the XML standard way of signing the content which is known as an enveloped XML digital signature here is an example of the assertion portion of an SML response note that this is not the whole response just the assertion portion and we want to prove the integrity of this assertion so we will apply some algorithms to this block of characters we begin by applying the exclusive canonical algorithm this defines how to treat whitespace and divine characters and non utf-8 encoded characters among other things then we will hash that result in this example we will use the sha-1 algorithm this will produce this hexadecimal value which we will convert to base64 and then save for later use next we need to make some room to insert an enveloped signature and then add the blank signing information we can see that there are three elements shown in red that do not have values yet the first value that we

XML Signatures can be applied to any digital content (data object), including XML. An XML Signature may be applied to the content of one or more resources. Enveloped or enveloping signatures are over data within the same XML document as the signature; detached signatures are over data external to the signature element.
To digitally sign an XML document Create a CspParameters object and specify the name of the key container. Generate an asymmetric key using the RSACryptoServiceProvider class. Create an XmlDocument object by loading an XML file from disk. Create a new SignedXml object and pass the XmlDocument object to it.
An XML digital signature (XML DSIG) is an electronic, encrypted, stamp of authentication on digital information such as messages. The digital signature confirms that the information originated from the signer and was not altered in transmission.
The digital signature confirms the integrity of the message. This signature ensures that the information originated from the signer and was not altered, which proves the identity of the organization that created the digital signature. Any change made to the signed data invalidates the whole signature.
The SignatureValue property represents the element of an XML digital signature using an array of bytes contained within the property. The element is a subelement of the element.
The value in the element is calculated by hashing the data in the element using the SHA1 hashing algorithm, encrypting the hash with the users private key (which corresponds to the public key in the certificate attached to the message), and converting the result to Base64 encoding. Note.
To verify the digital signature of an XML document To verify the document, you must use the same asymmetric key that was used for signing. Retrieve the public key using the RSACryptoServiceProvider class. Create an XmlDocument object by loading an XML file from disk.
How to Create an XML Signature Determine which resources are to be signed. This will take the form of identifying the resources through a Uniform Resource Identifier (URI). Calculate the digest of each resource. Collect the Reference elements. Signing. Add key information. Enclose in a Signature element.
