XML Encrypting/ Compression

[Guest]

Hello,

We are developing a CF application that uses a web service to return xml. Does anyone know of a tool that can compress, encrypt and encode the xml so that it can be sent via a web service, and then decompressed, decrypted and decoded at the client app?

There seem to be plenty of components that either compress, encrypt, or encode but not one that does all three.

Thanks in advance,

Simon

You can use SharpZipLib to compress/decompres the data. If you want an example (webservice+client) drop me an email ([email protected])

We use compression at either end using Sharp Zip Lib and an HttpModule.
Our preferred approach to encryption is to use SSL.

Cheers
Chris

if you really want Xml-Encryption with a Web Service,
then you would use WS-Security.
the server would use WSE 2.0 and the client would use the CF WSE bits.

these are getting moved into OpenNETCF, and are updated for WSE 2.0 RTM.

i dont know of any Web Service compression specification yet.

instead you might use DIME.
then you could compress the XML, and then encrypt that.
OpenNETCF.org has the System.Security.Cryptography namespace for encryption.

Thanks,
