Demonstrates Jwe.GetProtectedHeader, which copies the decoded shared JWE protected header into a JsonObject.

Dim success As Long
success = 0

Dim jwe As New ChilkatJwe

'  Load the JWE.
Dim jweCompact As String
jweCompact = "eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>"
success = jwe.LoadJwe(jweCompact)
If (success = 0) Then
    Debug.Print jwe.LastErrorText
    Exit Sub
End If

'  Copy the decoded shared JWE protected header into a JsonObject.  Only the protected header is
'  returned; it is not merged with the unprotected or per-recipient headers.
Dim json As New ChilkatJsonObject
success = jwe.GetProtectedHeader(json)
If (success = 0) Then
    Debug.Print jwe.LastErrorText
    Exit Sub
End If

json.EmitCompact = 0
Debug.Print json.Emit()
