Get the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

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

var
success: Integer;
jwe: TChilkatJwe;
jweCompact: WideString;
json: TChilkatJsonObject;

begin
success := 0;

//  Load the JWE.
jweCompact := 'eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>';
success := jwe.LoadJwe(jweCompact);
if (success = 0) then
  begin
    Memo1.Lines.Add(jwe.LastErrorText);
    Exit;
  end;

//  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.
json := TChilkatJsonObject.Create(Self);
success := jwe.GetProtectedHeader(json.ControlInterface);
if (success = 0) then
