- `SetDigestMethod(DigestMethod: Text)`: Sets the digest method Uniform Resource Identifier (URI) of the current Reference.
- `AddXmlDsigC14NTransformToReference(IncludeComments: Boolean)`: Adds a XmlDsigC14NTransform object to the list of transforms to be performed on the data before passing it to the digest algorithm.
- `AddXmlDsigExcC14NTransformToReference(InclusiveNamespacesPrefixList: Text)`: Adds a XmlDsigExcC14NTransform object to the list of transforms to be performed on the data before passing it to the digest algorithm.
- `SetCanonicalizationMethod(CanonicalizationMethod: Text)`: Sets the canonicalization algorithm that is used before signing for the current SignedInfo object.
- `SetXmlDsigExcC14NTransformAsCanonicalizationMethod(InclusiveNamespacesPrefixList: Text)`: Sets the XmlDsigExcC14NTransform as canonicalization algorithm that is used before signing for the current SignedInfo object.
- `SetSignatureMethod(SignatureMethod: Text)`: Sets the name of the algorithm used for signature generation and validation for the current SignedInfo object.
- `InitializeKeyInfo()`: Initializes a new instance of the KeyInfo class.
- `AddClause(KeyInfoNodeXmlElement: XmlElement)`: Adds a xml element of KeyInfoNode to the collection of KeyInfoClause.
- `AddKeyInfoClauseFromX509Certificate(X509CertBase64Value: Text; CertPassword: SecretText)`: Adds key information from an X509 certificate to the collection of KeyInfoClause.
- `LoadXml(SignatureElement: XmlElement)`: Loads a SignedXml state from an XML element.
- `InitializeDataObject()`: Initializes a new instance of the DataObject class.
- `AddObject(DataObjectXmlElement: XmlElement)`: Adds a xml element of DataObject object to the list of objects to be signed.
- `AddXmlDsigExcC14NTransformToReference()`: Adds a AddXmlDsigExcC14NTransformToReference object to the list of transforms to be performed on the data before passing it to the digest algorithm.
- `AddXmlDsigEnvelopedSignatureTransform()`: Adds a AddXmlDsigEnvelopedSignatureTransform object to the list of transforms to be performed on the data before passing it to the digest algorithm.
- `AddReferenceToSignedXML()`: Adds a Reference object to the Signed XML and clears Reference object.
- `ComputeSignature()`: Computes an Xml digital signature from Xml document.
- `CheckSignature(): Boolean`: Determines whether the signature verifies using the public key in the signature.
- `CheckSignature(XmlString: SecretText): Boolean`: Determines whether the Signature property verifies for the specified key.
- `CheckSignature(X509CertBase64Value: Text; X509CertPassword: SecretText; VerifySignatureOnly: Boolean): Boolean`: Determines whether the signature verifies for the specified X509Certificate2 and, optionally, whether the certificate is valid.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 1461 "SignedXml Impl."](../codeunit/1461.md) (32 calls: `AddClause → AddClause`, `AddKeyInfoClauseFromX509Certificate → AddKeyInfoClauseFromX509Certificate`, `AddObject → AddObject`, …)

## Recent changes

- 2026-10-07 [#10212 Add SetReferenceType method to SignedXml and SignedXmlImpl (#10139)](../../changes/bcapps/10212.md) (main, BC30, feature)

## Across versions

- Present in: BC23-30

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "SignedXml")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
