Document and reference integrity
Inspect each reference URI, transform chain, digest algorithm, and calculated digest result.
XML digital signatures
Sign, verify, and diagnose XMLDSIG workflows.
Use XML ValidatorBuddy Desktop or ValBuddy to work with XML signatures and understand failed verification with document, reference, digest, key, and certificate context.
Specialist workflow
Go beyond a pass-or-fail message.
Signature verification can fail at several layers. Grouped diagnostics help you determine whether the problem is in a reference, digest, transform, key, certificate, or signature value.
Key and certificate context
Review the available KeyInfo material and the certificate or key used by the workflow.
Desktop and CLI execution
Use interactive diagnostics in XML ValidatorBuddy and repeatable signing or verification through ValBuddy.
Actionable failure detail
Find the failing layer before changing the document.
- Reference URI and target information
- Digest and signature algorithms
- Transform and canonicalization context
- KeyInfo and certificate findings
- Source location for the affected signature
Web API boundary: the API verifies only the documented whole-document enveloped safe profile. It does not sign XML or establish certificate trust, signer identity, or general XMLDSIG support.
Make XML signature failures explainable.
Use XML ValidatorBuddy Desktop and ValBuddy on Windows.
Signature diagnostics in automation
Return focused verification evidence.
ValBuddy can verify XML Digital Signatures with -dsigverify and write expert diagnostics as JSON, XML, or HTML. An agent can use those reports to focus on certificate, key, KeyInfo, reference, transform, digest, or verification findings. Signature capabilities depend on the installed edition.
An agent may still send selected content or diagnostics to its model provider. XML processing may use network access when related resources resolve remote references.

Download and use XML ValidatorBuddy+ as your XML signature tool:
Get complete and affordable support for XML digital signatures and increase the security of your XML documents with the easy-to-use functionality provided by XML ValidatorBuddy+ Edition. Use the same Windows desktop tool to create signatures, verify signed XML documents, inspect failed XMLDSIG operations, and prepare diagnostic details for support or audit workflows.
XML Validator Buddy supports SHA-1, SHA-2 (SHA-256, SHA-384 and SHA-512) hash algorithms, together with RSA and HMAC keys. It is possible to create XML signatures using Windows® certificates, an arbitrary password or loaded from a standard PFX file.
Save time and run sign or verify batch tasks for digital signatures on any number of XML documents using the command line tool which is included in all installations of XML Validator Buddy. Learn more
