Struct SignContext 

pub struct SignContext<'a> { /* private fields */ }

XMLDSig signing context.

Implementations

impl<'a> SignContext<'a>

pub fn new(signing_key: &'a dyn SigningKey) -> Self

Create a signing context using the supplied private key.

pub fn key_info_writer(self, writer: &'a dyn KeyInfoWriter) -> Self

Configure signing to populate the direct <Signature>/<KeyInfo> placeholder.

pub fn xpath_here_semantics(self, semantics: XPathHereSemantics) -> Self

Select the node returned by XPath’s here() extension function.

The default follows XMLDSig and returns the <XPath> parameter. XPathHereSemantics::XmlSecLegacy is available only for producing signatures compatible with libxmlsec1’s <Transform> interpretation.

pub fn sign_template(&self, xml: &str) -> Result<String, SigningError>

Sign XML that already contains a <Signature> template.

The template must include empty <DigestValue> and <SignatureValue> targets. The pipeline fills reference digests, reparses the result, canonicalizes <SignedInfo>, signs those canonical bytes, and fills the base64 <SignatureValue>.

pub fn sign_with_builder( &self, xml: &str, builder: &SignatureBuilder, ) -> Result<String, SigningError>

Build a signature template, append it to the source root, then sign it.
