Encrypt a JWE with a Symmetric Wrapping Key

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetWrappingKey, which sets the symmetric key-wrapping key for a recipient. The key bytes are supplied in a named encoding such as hex or base64.

Local $bSuccess = False

;  Protected header: AES key-wrap with AES-256-GCM content encryption.
$oHeader = ObjCreate("Chilkat.JsonObject")
$oHeader.UpdateString("alg","A256KW")
$oHeader.UpdateString("enc","A256GCM")
$bSuccess = $oJwe.SetProtectedHeader($oHeader)
If ($bSuccess = False) Then
    ConsoleWrite($oJwe.LastErrorText & @CRLF)
    Exit
EndIf

;  Set the symmetric key-wrapping key for recipient 0.  The key bytes are provided in the named
;  encoding (here base64).  In production, obtain the key from a secure source rather than hard-coding
;  it.
