About Virchk

Virchk.cs is a file scanner utility, which traverses the files in a directory and all it's sub directories, to generate a MD5 hash signature footprint of the targeted extensions file.

This utility is authored by me (Ashish Banerjee). This utility is the C# avatar of a Java utility, also authored by me a couple of years back.

I re-wrote this utility from Java to C#, to gain insights into similarities and disparities between the two languages.

I found the Java utility (which uses similar algo. to this C# utility) useful for ensuring my virus scanner is not hood winked by emerging viruses. It has saved my day on more than one occasions.

I have also found this utility for version control of documents and source codes. To protect them against accidental or intentional changes.
