; Demonstrates how to create a JWT using an certificate's private key.

$oCert = ObjCreate("Chilkat.Cert")

; Load an ECC private key from a PEM file.
Local $bSuccess = $oCert.LoadPfxFile("c:/temp/myPfx.pfx","pfxPassword")
If ($bSuccess <> True) Then

    Exit
EndIf

$oJwt = ObjCreate("Chilkat.Jwt")

; Build the JOSE header
$oJose = ObjCreate("Chilkat.JsonObject")
; Note: The IsEcdsa function was added in Chilkat v10.1.0
If ($oCert.IsEcdsa() = True) Then
    ; Use ES256.  Pass the string "ES384" or "ES512" to use ECC with SHA-384 or SHA-512.
    $oJose.AppendString("alg","ES256")
Else
    ; Probably RSA...
    ; Use RS256.  Pass the string "RS384" or "RS512" to use RSA with SHA-384 or SHA-512.
    $oJose.AppendString("alg","RS256")
EndIf

$oJose.AppendString("typ","JWT")

; Now build the JWT claims (also known as the payload)
$oClaims = ObjCreate("Chilkat.JsonObject")
$oClaims.AppendString("iss","http://example.org")
$oClaims.AppendString("sub","John")
$oClaims.AppendString("aud","http://example.com")

; Set the timestamp of when the JWT was created to now.
Local $iCurDateTime = $oJwt.GenNumericDate(0)
$oClaims.AddIntAt(-1,"iat",$iCurDateTime)

; Set the "not process before" timestamp to now.
$oClaims.AddIntAt(-1,"nbf",$iCurDateTime)

; Set the timestamp defining an expiration time (end time) for the token
; to be now + 1 hour (3600 seconds)
$oClaims.AddIntAt(-1,"exp",$iCurDateTime + 3600)

; Produce the smallest possible JWT:
$oJwt.AutoCompact = True

; Create the JWT token.
Local $sToken = $oJwt.CreateJwtCert($oJose.Emit(),$oClaims.Emit(),$oCert)

ConsoleWrite($sToken & @CRLF)
