2004-06-10  Gert Driesen <[email protected]>

	* SignedXml.cs: API signature fixes

2004-06-04  Atsushi Enomoto <[email protected]>

	  Namespace fixup is required when signing prefixed xml.

2004-06-04  Atsushi Enomoto <[email protected]>

2004-05-13  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Update TODO informations.

2004-05-13  Atsushi Enomoto <[email protected]>

	* XmlDsigBase64Transform.cs :
	  LoadInput() should retrieve all the descendants.
	  GetOutput() should handle nodes without digging into child nodes.

2004-05-05  Atsushi Enomoto <[email protected]>

	* SignedXml.cs,
	  Transform.cs : code cleanup. #if !NET_1_0 -> #if NET_1_1.
	* XmlDsigBase64Transform.cs : Should not output the content of the
	  selected element nodes. Put text content only those text nodes are
	  in the node list.
	* XmlDsigEnvelopedSignatureTransform.cs : removed MonoTODO.
	* XmlDsigXsltTransform.cs : Use XmlResolver to load document and
	  to transform. Throw null reference exception explicitly when
	  the input was not loaded.

2004-04-02  Lluis Sanchez Gual  <[email protected]>

	* XmlDsigEnvelopedSignatureTransform.cs, XmlDsigXPathTransform.cs,
	XmlDsigXsltTransform.cs: Fixed build for net_1_0 profile.

2004-03-30  Sebastien Pouliot  <[email protected]>

	* Reference.cs: Changed code to use CryptoConfig to create transforms.
	This is "the" way to do it (e.g. to allow new transforms to be added)
	but cause problems when using VS.NET for debugging. Old code is still
	present, but commented, for that cause.

2004-03-27  Atsushi Enomoto <[email protected]>

	* SignedXml.cs : namespace nodes also should be supplied for enveloped
	  objects.
	* KeyInfoRetrievalMethod.cs : Keep input element as well as others.

2004-03-27  Atsushi Enomoto <[email protected]>

	* SignedXml.cs : XPath transformation output is not type of Stream.
	  Fix to support them by canonicalizing it.

2004-03-27  Atsushi Enomoto <[email protected]>

	* XmlDsigXsltTransform.cs : GetOutput() now just returns
	  transformation output.

2004-03-27  Atsushi Enomoto <[email protected]>

	* SignedXml.cs : Added xmlns support for Manifest.

2004-03-26  Sebastien Pouliot  <[email protected]>

	* Manifest.cs: New. Support for <Manifest> in Xml Digital Signature.
	This should help us to validate more tests from the Phaos suite.
	Note: Microsoft doesn't support this and we only support it for
	verification (not signature generation).
	* SignedXml.cs: Added support for Manifest, including recursive 
	manifests. Made some changes to reuse existing code as much as 
	possible. Better support for local/remote files - but requires
	catching an Uri exception for local files :-(.
	* XmlSignature.cs: Added constants for Manifest element and URI.

2004-03-26  Atsushi Enomoto <[email protected]>

	* SignedXml.cs :
	  - Use specified (or default) XmlResolver to get external resource,
	    instead of using WebRequest directly. Also modified it easier.
	  - ApplyTransform() : Clone only when it is required. Handle 
	    transformation output other than Stream.
	  - Even if applicable key was not found in GetHash(), don't throw
	    crypto exception every time and just return false (MS does it).
	    Throw an exception only when no key was specified as KeyInfo.
	* XmlDsigEnvelopedSignatureTransform.cs : Fixed get_OutputTypes which
	  incorrectly set InputTypes internally.
	* XmlDsigXPathTransform.cs : Context namespace nodes in loaded 
	  transform parameter (i.e. <XPath>..</XPath>) should be registered
	  to XsltContext. Otherwise prefix binding error occurs.
	  Just filter attribute node, instead of filtering attribute children.

2004-03-25  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Added try/catch in CheckSignatureWithKey to return 
	false on exceptions. Fix signature-rsa-detached-xslt-transform-bad
	-retrieval-method.xml in the Phaos test suite.

2004-03-24  Atsushi Enomoto <[email protected]>

	* Reference.cs, Signature.cs : They should keep input element and hence
	  keep namespace context nodes on LoadXml() as same as SignedInfo.
	* SignedXml.cs : Fixed SignedInfoTransformed() to fill context 
	  namespace nodes into the input document (unlike other classes, there
	  seems no other way to keep ns-nodes here).
	  Now some of W3C phaos xmldsig test passes.

2004-03-23  Atsushi Enomoto <[email protected]>

	* SignedInfo.cs : It holds input element and directly returns it
	  unless the properties are not set.
	  Throw CryptographicException when Reference is empty *and* GetXml()
	  is *created*. (when just returning input element, no exception is
	  thrown).

2004-03-23  Atsushi Enomoto <[email protected]>

	* DataObject.cs : It now holds element instead of each parameters.
	  Avoid loading element content to different document unless its
	  properties were modified (to keep namespace node context).

2004-03-20 Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Removed unused (and commented) ComputeHash method.

2004-03-19  Atsushi Enomoto <[email protected]>

	* XmlDsigXPathTransform.cs : just found stupid bug.

2004-03-19  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Lot of small changes to complete TODOs and to match 
	the new unit tests.

2004-03-17  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: The old method was working for creating signature -
	so it was reintroduced for (only) this case.

2004-03-17  Atsushi Enomoto <[email protected]>

	* SignedXml.cs : the result from enveloped signature transform should
	  be canonicalized before getting its hash.
	* XmlDsigEnvelopedSignatureTransform.cs : in XPath selection,
	  if the node is Signature itself it is not allowed.
	  PreserveWhitespace is required.

2004-03-16  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Changed (again). This time we use the Stream when 
	loading the document. We now pass 14 out of 15 of the Merlin's
	tests (including one that MS fails). The only failing test is the
	one that use the EnvelopedTransform (unfinished).

2004-03-16  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Commented my last changes to SignedXml as it made other
	unis tests fail (in the c14n-izer).

2004-03-16  Atsushi Enomoto <[email protected]>

	* XmlDsigNodeList.cs : removed BOM from code file.

2004-03-16  Atsushi Enomoto <[email protected]>

	* XmlDsigNodeList.cs : added.
	* XmlDsigXPathTransform.cs : removed XmlDsigNodeList class.
	* XmlDsigEnvelopedSignatureTransform.cs :
	  Implemented GetOutput(). However, it is totally MS behavior
	  dependent and not based on the spec (we can reimplement it based on
	  improved XmlDsigXPathTransform).
	* SignedXml.cs : in GetOutput(), accept XmlNodeList input too.

2004-03-15  Sebastien Pouliot  <[email protected]>

	* SignedXml.cs: Now use the original Signature element before applying
	the C14N transformation. Added a check for null in LoadXml.

2004-03-14  Atsushi Enomoto <[email protected]>

	* XmlDsigXPathTransform.cs : implemented GetOutput() (with some 
	  internal XPath context classes).

2004-03-13  Atsushi Enomoto <[email protected]>

	* XmlDsigXsltTransform.cs : LoadInnerXml() should just load stylesheet
	  and LoadInput() should just load transformed document.
	  Transformation should be done in GetOutput() because either of the
	  stylesheet or input can be loaded in prior. Adjusted code format.

2004-03-12  Sebastien Pouliot  <[email protected]>

	* Signature.cs: KeyInfo isn't required in schema.
	* SignedInfo.cs: Added support for missing HMACOutputLength.
	* SignedXml.cs: Added support to download a reference (experimental).
	Now throw exception for unknown hash algorithm or canonicalization 
	methods. Changed GetPublicKey to iterate all available keys (not just
	the first one).

2004-03-09  Atsushi Enomoto <[email protected]>

	* KeyInfo.cs : Attribute Id was not handlded.
	* KeyInfoX509Data.cs : all array members return null when there are
	  no such contents. Just find child elements, not descendants.
	* SignedXml.cs : key is not always required when CheckSignature() is
	  called.
	* XmlDsigXsltTransform.cs : LoadInput should allow node list.
	* XmlSignature.cs : added GetChildElements().

2004-03-09  Atsushi Enomoto <[email protected]>

	* KeyInfoX509Data.cs : trivial local var name fix.

2004-03-09  Atsushi Enomoto <[email protected]>

	* KeyInfoX509Data.cs,
	  Reference.cs,
	  SignedInfo.cs,
	  XmlSignature.cs : GetElementsByTagName() should be eliminated or
	  at least should use namespace URI.

2004-03-04  Atsushi Enomoto <[email protected]>

	* KeyInfo.cs :
	  Fixed LoadXml() to skip text nodes as MS.NET does.
	  Uncommented out RSAKeyValue.
	* Signature.cs : Fixed LoadXml(). Don't use GetElementsByTagName()
	  that incorrectly acquires descendants. Throw CryptographicException
	  if required elements were not found.
	* Transform.cs : added internal GetResolver().
	* XmlDsigXPathTransform.cs,
	  XmlDsigXsltTransform.cs : use XmlResolver.

2004-02-19  Tim Coleman <[email protected]>
	* SymmetricKeyWrap.cs:
		Add AES Key Wrap
	* EncryptedXml.cs:
		Add calls to SymmetricKeyWrap

2004-02-11  Sebastien Pouliot  <[email protected]>

	* Reference.cs: Added LoadInnerXml to transforms. Removed unused 
	variable.
	* Transform.cs: Import GetInnerXml in GetXml.
	* XmlDsigBase64Transform.cs: Now use a StreamWriter to avoid multiple
	allocations.
	* XmlDsigC14NTransform.cs: Added Stream support to LoadInput
	* XmlDsigXPathTransform.cs: Fixed GetInnerXml to include xpath 
	expression and LoadInput. It nows match MS implementation but doesn't
	work like I think it should (but neither is MS implementation).

2004-02-10  Tim Coleman <[email protected]>
