Convert Certificate from PEM to DER

Convert a PEM formatted certificate file (.cer, .crt, .pem) to DER format (.cer, .der). The Chilkat certificate class/object is a freeware component that is included in many of the Chilkat downloads.

Dim cert As New ChilkatCert

Dim success As Long

'  LoadFromFile will load either PEM and DER formatted files.
'  It automatically recognizes the file format based on the
'  file contents.
success = cert.LoadFromFile("chilkat.crt")
If (success <> 1) Then
    MsgBox cert.LastErrorText
    Exit Sub
End If

MsgBox cert.SubjectDN

success = cert.ExportCertDerFile("chilkat.der")
If (success <> 1) Then
    MsgBox cert.LastErrorText
    Exit Sub
End If

MsgBox "success!"
