Get the JWS Payload into BinData

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetPayloadBd, which writes the payload of a loaded JWS as raw bytes into a BinData.

var
success: Integer;
jws: TChilkatJws;
jwsCompact: WideString;
bdPayload: TChilkatBinData;

begin
success := 0;

jws := TChilkatJws.Create(Self);

//  Load the JWS compact serialization.
jwsCompact := 'eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>';
success := jws.LoadJws(jwsCompact);
if (success = 0) then
  begin
    Memo1.Lines.Add(jws.LastErrorText);
    Exit;
  end;

//  Get the JWS payload as raw bytes into a BinData.
