What is CanonicalizationMethod algorithm?

What is CanonicalizationMethod algorithm?

The required CanonicalizationMethod element defines the algorithm used to canonicalize the SignedInfo element before it is signed or validated. Canonicalization is the process of converting XML content to a canonical form, to take into account changes that can invalidate a signature over that data.

What is SignatureValue in XML signature?

The SignatureValue element contains the Base64 encoded signature result – the signature generated with the parameters specified in the SignatureMethod element – of the SignedInfo element after applying the algorithm specified by the CanonicalizationMethod .

What is the purpose of XML signature?

XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere.

How do I create an XML signature?

How to Create an XML Signature

1. Determine which resources are to be signed. This will take the form of identifying the resources through a Uniform Resource Identifier (URI).
2. Calculate the digest of each resource.
3. Collect the Reference elements.
4. Signing.
5. Add key information.
6. Enclose in a Signature element.

How do I validate an XML signature?

Create a new SignedXml object and pass the XmlDocument object to it. Find the < signature > element and create a new XmlNodeList object. Load the XML of the first < signature > element into the SignedXml object. Check the signature using the CheckSignature method and the RSA public key.

What are the elements in XML Signature?

Understanding XML Digital Signature Elements

• Element. Each signed resource (the transmitted XML document, in this case) that the signature authenticates has to be enclosed within the elements.
• Element.
• Element.
• Element.
• Element.

What is a URI API?

A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource. Each URI begins with a scheme name, as defined in Section 3.1, that refers to a specification for assigning identifiers within that scheme.
