Belgium eID Card Reader Application

A friend of mine, Tim, asked me to write up a simple application
that's able to read out the Belgium ID cards.

This is what I ended up with...

A few things you need to know:

• Install the driver/application http://eid.belgium.be/nl/binaries/BeidMW35-Sdk-6193-signed_tcm147-93244_tcm227-114955.msi

• Reference the Interop.EIDLIBCTRLLib.dll
• Target the x86 platform (the dll only exists in a 32bit flavour)

The actual eID Object : were all the “Magic” Happens…

PDF Layer Merger

 

Recently I’ve created a simple .NET tool, to merge 2 PDF files, one as a layer on top of the other.

The reason behind this, was to be able to digitally remark/comment/mark-up on a PDF file using AutoCAD.  People tend to print out a PDF file, use some highlighters and draw some clouds and comments on this PDF, only to re-scan this afterwards.
This is the way we used to work, but today we live in a digital era…

The tool has been built in VB.NET targeting the NET 2.0 framework, with the use of the excellent PDF library iTextSharp (based on iText).

Snippet of the actual transformation function:

  
    ''' 

    ''' Combines two source pdf's to one single pdf.
    ''' 
    ''' The file-location incl. the name of the original pdf.
    ''' The file-location incl. the name of the mark-up pdf.
    ''' The file-location incl. the name of the generated combined pdf.
    ''' The name which the added mark-up layer will have in the new pdf.
    ''' The transformation which is executed on the original pdf: rotation, scaleX, scaleY, offsetX, offsetY
    ''' Return boolean indication whether the combination of the pdf's was successful.
    ''' 
    Public Function PDFCombineLayer(ByVal sourceOriginal As String, ByVal sourceMarkup As String, ByVal destination As String, Optional ByVal NewLayer As String = "SOURCE-DRAWING", Optional ByVal Transform As String = "0;1;1;0;0") As Boolean

Secunia Personal Software Inspector (PSI)

 

Upon stumbling through the web, I found a nice tool to check the installed software for security issues and out-dated programs.
So I thought I’d shared it with you…

They even have an online scanning tool, so you don’t need to install the application http://secunia.com/vulnerability_scanning/online/

FREE PC Security for Home Users

The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Attacks exploiting vulnerable programs and plug-ins are rarely blocked by traditional anti-virus and are therefore increasingly "popular" among criminals.
The only solution to block these kind of attacks is to apply security updates, commonly referred to as patches.
Patches are offered free-of-charge by most software vendors, however, finding all these patches is a tedious and time consuming task.
Secunia PSI automates this and alerts you when your programs and plug-ins require updating to stay secure.
Download the Secunia PSI now and secure your PC today - free-of-charge.
