My nature of work involves debugging and creating Windows Services for my product. This makes me often run into issues with my SEP which screams that a few input files and temporary content that it manipulates are sometimes harmful content. And in such cases I normally use the False Positive Submission tool in this URL ( to get SEP team alerted regarding the same.

The False Positive Report Collector needs the MD5 hash of the file which we are intending to submit to the SEP team. Whilst on the internet we have a number of MD5 calculators that come bundled with other things a simple tool intended only for file hash generation and quicker tool to the webpage would be really helpful. With this intent I have a small tool hand-coded myself using System.Security.Cryptography namespace of .NET framework.

It has a quick File Selector button to access the file, quickly calculate the MD5 hash of the file, display it and optionally (if desired by the user) place the calculated hash to the system clipboard so that the user can directly paste it into the textbox of False Positive Report Collector.

Sample Screenshots of the tool:

SHA 512 hash:

Do send me your feedback on the tool.
