🔒 Certificate conversion with openssl

Also certificate signing requests and certificate export

I bought a wildcard certificate for use with multiple servers and subdomains. The file was a PKCS#7 certificate file (p7b). I needed different formats with and without separate key files (pem, pfx, and crt).

Word to PDF Batch Conversion

I needed to convert a bunch of Word files to pdf. I found this visual basic code that basically opens all files one after another in Word and saves a pdf version.

'Convert .doc or .docx to .pdf files via Send To menu
Set fso = CreateObject("Scripting.FileSystemObject")
For i= 0 To WScript.Arguments.Count -1
   docPath = WScript.Arguments(i)
   docPath = fso.GetAbsolutePathName(docPath)
   If LCase(Right(docPath, 4)) = ".doc" Or LCase(Right(docPath, 5)) = ".docx" Then
      Set objWord = CreateObject("Word.Application")
      pdfPath = fso.GetParentFolderName(docPath) & "\" & _
	fso.GetBaseName(docpath) & ".pdf"
      objWord.Visible = False
      Set objDoc = objWord.documents.open(docPath)
      objDoc.saveas pdfPath, 17
      objDoc.Close
      objWord.Quit   
   End If   
Next

Just save it as a vbs somewhere and add a ahortcut to the context menu.

C:\Users\%username%\AppData\Roaming\Microsoft\Windows\SendTo

You can select multiple files at once and they get converted one by one.

ISO8601 Timestamps in Batch Files

Sometimes you just need the date and time for something.

Simple manual Backup with robocopy

I wanted to have a “simple” solution for an (external) backup of my USB stick. The simplest way would be copy and paste, but I wanted something more robust. So what gets you robust copying of files in Windows? Robust File Copy – robocopy –, of course.

I use this manually, but for internal or permanently attached drives etc. this could be automated with task planning and removing the user promts.
