使用KNIME 4.1.2，Windows 10，x64，JDK 1.8，Java编辑代码段
我正在尝试使用Java代码段读取CSV文件，然后使用公共密钥pgp对其加密，然后将生成的文件保存到临时文件夹中
我一直在尝试使用BounceCastle库v1.65

        try {
        encryptFile(    
                  "encryptedfile.csv.pgp",
                  "original.csv",
                  "/key/pub.asc",
                  false,
                  false);
       } catch(Exception e) {
        out_result = "fail";
       }

挑战是，我在控制台中间歇性地收到以下错误，并且我不清楚我在错误地提供给库的内容（不包括）。造成混淆的原因是它是间歇性的，有时会产生正确加密的文件。
