The program that I am working on saves the snapshot of the current state

  • 0

The program that I am working on saves the snapshot of the current state to a xml file. I would like to store this in database (as blob) instead of xml.

Firstly, I think xml files are quite space-consuming and redundant, so we would like to compress the string in some way before storing in in the database. In addition, we would also like to introduce a simple cryptography so that people won’t be able to figure out what it means without at least a simple key/password.

Note that I want to store it in the database as blob, so zipping it and then encrypting the zip file won’t do, I guess.

How can I go about doing this?

    Compress the XML data with DeflateStream and write it’s output to a MemoryStream. Then call .ToArray() method to obtain your blob data. You can also do encryption with .NET in a similar way as well (after compression of course). If you believe deflate is not enough to save space, then try this library: XWRT.
