Software Tool Updates

I've updated several tools today. The changes include a bug fix and a small expansion of capability as listed below. :)

Oh, and an update to the Secure Parcel Delivery program is on the way.



MyCryptInfo -> version 1.4

The tool is expanded to detect more block cipher modes of operation. That is, the algorithms employed to make a block cipher encrypt a chunk of data bigger than the native block size. I noticed that some new modes had been added in the Microsoft header files since last I looked. Although these modes don't seem to be available with the Microsoft native Cryptographic Service Providers (CSPs), they must be available in some third party CSPs. The modes added are:

  • CBCI - ANSI CBC Interleaved
  • CFBP - ANSI CFB Pipelined
  • OFBP - ANSI OFB Pipelined
  • CBCOFM - ANSI CBC + OF Masking
  • CBCOFMI - ANSI CBC + OFM Interleaved

MyNetwork -> version 1.3

Fixed a bug in the formatting of the lease times for interfaces with DHCP enabled. This turned out to be a 32-bit to 64-bit portability issue on windows.

MTFileTransfer -> version 1.3

Fixed the same bug in the formatting of the lease times for interfaces with DHCP enabled.


Open Sourcing Some Example Code

In order to make some examples of thread and TCP/IP server management clearer I decided to clean up the full, standalone project and post it here for your download. The project files build with Visual Studio 2008 (VC9) for Release and Debug mode on both x86 and x64 systems. Note that this project is simply a demonstration of thread and TCP/IP server management on an MS Windows system. A full-fledged application would have much more in the way of error checking, unit tests, and other infrastructure. :)

These are all plain source code files, not executables, and I'm making them available under the Mozilla trifecta license.



Updated Software Tools

OK! :) After too much time I have completed updating several tools. The updates include fixing some bugs, modifying the code to run on 64-bit Windows systems, and general stuff like that. The tools updated in this batch include

I'm still working on the IP Packet Sniffer and IP Packet Filter Configurator tools. The Windows OS has had enough changes that their usefulness is in question -- I need to evaluate that. I have hope that I can work out just how munged raw sockets have become.

I'm still working, so come back later. ;)
