(VBScript) Iterate Keys and Certs in PEMDemonstrates how to access each of the private keys and certs contained within a PEM. Note: This example requires Chilkat v11.0.0 or greater.
Dim fso, outFile Set fso = CreateObject("Scripting.FileSystemObject") 'Create a Unicode (utf-16) output text file. Set outFile = fso.CreateTextFile("output.txt", True, True) success = 0 ' This example assumes the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. set pem = CreateObject("Chilkat.Pem") ' Load the PEM from a file. ' If the PEM is encrypted, provide a password. Otherwise pass an empty string for the password. password = "myPassword" success = pem.LoadPemFile("../myPemFiles/myPem.pem",password) If (success = 0) Then outFile.WriteLine(pem.LastErrorText) WScript.Quit End If ' Note: If the app already has the PEM pre-loaded in a string variable, then load it ' by calling LoadPem instead. pemContent = "... the PEM contents ..." success = pem.LoadPem(pemContent,password) ' Check for success as before..
