XML signatures are a standard for digital signatures in the XML data format, and they allow you to authenticate and protect the integrity of data in XML and web service transactions. This article will give you an overview of XML signatures and show you how to use the API in your applications. RFC 2828 defines a digital signature as “a value computed with a cryptographic algorithm and appended to a data object in such a way that any recipient of the data can use the signature to verify the data’s origin and integrity. An XML signature is a digital signature with several key properties. It defines a process and a format for generating digital signatures in the XML format, and it has many additional features.

For instance, it allows you to sign more than one piece of data — in binary or XML — and to use any underlying cryptographic signature algorithm. An XML signature can sign arbitrary data, whether it is XML or binary. It can also sign only a portion or a subset of an XML document rather than the entire document. A detached signature is over data that is external to the Signature element. This could be data outside of the document, such as a web page retrieved by way of HTTP, but it could also be data that is in the same document, such as a sibling element of the signature.
