Although issuer name and certificate should be sufficient to identify + the certificate the implementation in XMLSec is broken, both for Windows and mozilla. + The reason is that they use functions to find the certificate which take as parameter + the DER encoded ASN.1 issuer name. The issuer name is a DName, where most attributes + are of type DirectoryName, which is a choice of 5 string types. This information is + not contained in the issuer string and while it is converted to the ASN.1 name the + conversion function must assume a particular type, which is often wrong. For example, + the Windows function CertStrToName will use a T.61 string if the string does not contain + special characters. So if the certificate uses simple characters but encodes the + issuer attributes in Utf8, then CertStrToName will use T.61. The resulting DER encoded + ASN.1 name now contains different bytes which indicate the string type. The functions + for finding the certificate apparently use memcmp - hence they fail to find the + certificate. + */ + void setX509Certificate( + sal_Int32 nSecurityId, + const OUString& ouX509IssuerName, + const OUString& ouX509SerialNumber, + const OUString& ouX509Cert, + const OUString& ouX509CertDigest, + svl::crypto::SignatureMethodAlgorithm eAlgorithmID); + + void addEncapsulatedX509Certificate(const OUString& rEncapsulatedX509Certificate); + + void setGpgCertificate( + sal_Int32 nSecurityId, + const OUString& ouCertDigest, + const OUString& ouCert, + const OUString& ouOwner); + + void setDate( + sal_Int32 nSecurityId, + const css::util::DateTime& rDateTime ); + void setDescription(sal_Int32 nSecurityId, const OUString& rDescription); + void setSignatureLineId(sal_Int32 nSecurityId, const OUString& rSignatureLineId); + void + setSignatureLineValidGraphic(sal_Int32 nSecurityId, + const css::uno::Reference& xValidGraphic); + void setSignatureLineInvalidGraphic( + sal_Int32 nSecurityId, const css::uno::Reference& xInvalidGraphic); + + bool WriteSignature( + const css::uno::Reference< css::xml::sax::XDocumentHandler >& xDocumentHandler, + bool bXAdESCompliantIfODF); + + /* + * For signature verification + */ + void collectToVerify( const OUString& referenceId ); + void addSignature( sal_Int32 nSignatureId ); + css::uno::Reference< css::xml::sax::XDocumentHandler > const & createSignatureReader(XMLSignatureHelper& rXMLSignatureHelper, sal_Int32 nType = 0); + void releaseSignatureReader(); + +public: + /* Interface methods */ + + /* + * XSAXEventKeeperStatusChangeListener + */ + virtual void SAL_CALL blockingStatusChanged( sal_Bool isBlocking ) override; + virtual void SAL_CALL collectionStatusChanged( + sal_Bool isInsideCollectedElement ) override; + virtual void SAL_CALL bufferStatusChanged( sal_Bool isBufferEmpty ) override; + + /* + * XSignatureCreationResultListener + */ + virtual void SAL_CALL signatureCreated( sal_Int32 securityId, css::xml::crypto::SecurityOperationStatus nResult ) override; + + /* + * XSignatureVerifyResultListener + */ + virtual void SAL_CALL signatureVerified( sal_Int32 securityId, css::xml::crypto::SecurityOperationStatus nResult ) override; + + /// Writes XML elements inside a single OOXML signature's element. + bool WriteOOXMLSignature(const css::uno::Reference& xRootStorage, const css::uno::Reference& xDocumentHandler); + /// Exports an OOXML signature, called by WriteOOXMLSignature(). + void exportOOXMLSignature(const css::uno::Reference& xRootStorage, const css::uno::Reference& xDocumentHandler, const SignatureInformation& rInformation); +}; + +#endif + +/* vim:set shiftwidth=4 softtabstop=4 expandtab: */ -- cgit v1.2.3
