3 years ago a friend of mine asked me about how to enhance FCIV.exe utility functionality with PowerShell. Microsoft is not developing this tool anymore and you have to write your own tools or wrappers for fciv.exe to get required functionality.

I decided to write completely new tool from scratch by using only native PowerShell code. First version of PsFCIV was released about 3 years ago only for Russian-language audience. However there are many requests from English-language visitors. For example, users request new hashing algorithm support (SHA2 family) and other checking options, like file size and last modification timestamp checking. I made a lot of performance and reliability improvements, so new version works much faster than PsFCIV 1.0. Also I added support for SHA2 hashing algorithms. As the result, I was able to release a new updated PsFCIV 2.0 tool on TechNet Gallery:

PowerShell File Checksum Integrity Verifier (PsFCIV).
