Editing XML Signature (section)

{{short description|XML syntax for digital signatures}}
'''XML Signature''' (also called ''XMLDSig'', ''XML-DSig'', ''XML-Sig'') defines an [[XML]] syntax for [[digital signatures]] and is defined in the [[W3C recommendation]] [http://www.w3.org/TR/xmldsig-core/ XML Signature Syntax and Processing]. Functionally, it has much in common with [[PKCS 7|PKCS #7]] but is more extensible and geared towards signing XML documents. It is used by various [[World Wide Web|Web]] technologies such as [[SOAP]], [[Security Assertion Markup Language|SAML]], and others.

XML signatures can be used to sign data&ndash;a '''resource'''&ndash;of any [[MIME#Content-Type|type]], typically XML documents, but anything that is accessible via a [[Uniform Resource Locator|URL]] can be signed. An XML signature used to sign a resource outside its containing XML document is called a [[detached signature]]; if it is used to sign some part of its containing document, it is called an '''enveloped''' signature;<ref>{{cite web | url=https://www.w3.org/TR/xmldsig-core/#def-SignatureEnveloped | title=XML Signature Syntax and Processing Version 1.1 }}</ref> if it contains the signed data within itself it is called an '''enveloping''' signature.<ref>{{cite web | url=https://www.w3.org/TR/xmldsig-core/#def-SignatureEnveloping | title=XML Signature Syntax and Processing Version 1.1 }}</ref>
