Done.

CMSSignedData csd = new CMSSignedData(byteArr);

if (csd.getSignedContent() == null) {
            byte[] contentBytes;
            if (!isIE) {
                contentBytes = data.getBytes();
            } else {
                //UnicodeLittleUnmarked = Sixteen-bit Unicode Transformation Format, little-endian byte order 
                contentBytes = data.getBytes("UnicodeLittleUnmarked");
            }
            CMSProcessable cmsProcesableContent = new CMSProcessableByteArray(contentBytes);
            csd = new CMSSignedData(cmsProcesableContent, byteArr);
        }
