How to output the public part of a private key:
Demonstrates how to duplicate this OpenSSL command:
openssl pkey -in private.pem -pubout -out pubkey.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
set pkey = CreateObject("Chilkat.PrivateKey")
' Load the private key from an PEM file:
success = pkey.LoadPemFile("private.pem")
If (success = 0) Then
outFile.WriteLine(pkey.LastErrorText)
WScript.Quit
End If
set pubKey = CreateObject("Chilkat.PublicKey")
success = pkey.ToPublicKey(pubKey)
success = pubKey.SavePemFile(0,"pubKey.pem")
If (success <> 1) Then
outFile.WriteLine(pubKey.LastErrorText)
WScript.Quit
End If
outFile.WriteLine("Success.")
outFile.Close
