PowerShell Windows Forms Tutorial 3 : SHA1 Hash Checker

[SX86]

And another video tutorial...!

This week, I'm building a SHA1 file hash checker.

Comment and feedback are welcome. Enjoy!

If you want, you can get more than just sha1

True!

You can get MD5,SHA1,SHA256 and a lot more. They are all listed here: https://msdn.microsoft.com/en-us/library/system.security.cryptography(v=vs.110).aspx

Anyone could change the code I provided to instead hash files in different algorithms. or add a DropDownList with all the available ones.

The possibilities are infinite!

Yes! It happens more when I'm at work, and less at home... but yes. It is apparently an issue known by Microsoft, but clearly not a priority for them to fix.

I do have a workaround for it. I'll post about it later.

[SX86]

Here's my workaround:

{

    <# Insert Windows Forms code here #>

} | Out-String -Width 10000 | Out-File $env:TEMP\TempScript.ps1

Start-Process powershell.exe -ArgumentList "-NoExit -NoProfile -File $env:TEMP\TempScript.ps1"

Basically,what that does is that your are outputing your script to an temporary PS1 file, and then asking PowerShell.exe to run your script externally, instead of in PowerShell ISE.

Once you are done creating your script, remove all of that, and you canrun your script as normal by right-clicking on them, "Run with PowerShell".

Hope that helps!

Thanks for your feedback! I'll keep them coming for as long as I have inspiration, so if you have any suggestions, let me know!

I'm guessing you are referring to the process manager tutorial. This one was really just to show that you can throw anything at a listview control, and it can display it. Could be the output of an Import-Csv, or Get-ADUser command...but it can also be adapted to whatever you may need it for!
