在使用符号加密然后解密和验证时，我在验证时不断在流中获取未知对象。消息完整性检查已通过，但是当我尝试在解密后的下一行进行验证时，出现上述错误。

    private static void encryptFile(
    String outFileName,
    OutputStream out,
    String fileName,
    PGPPublicKey encKey,
    String sKeyFileName,
    char[] passPhrase,
    boolean armor,
    boolean withIntegrityCheck)
    throws Exception
{
    if (armor)
    {
        out = new ArmoredOutputStream(out);
    }

    try
    {


        byte[] bytes = PGPKeyUtil.compressFile(fileName, CompressionAlgorithmTags.ZIP);


        PGPEncryptedDataGenerator encGen = new PGPEncryptedDataGenerator(
            PGPEncryptedData.CAST5, withIntegrityCheck, new SecureRandom(), "BC");
        encGen.addMethod(encKey);

        OutputStream cOut = encGen.open(out, bytes.length);

        cOut.write(bytes);
        cOut.close();
        out.close();

        cOut.close();


        if (armor)
        {
            out.close();
        }

        encGen.close();

    }
    catch (PGPException e)
    {
        System.err.println(e);
        if (e.getUnderlyingException() != null)
        {
            e.getUnderlyingException().printStackTrace();
        }
    }
} …

它说List.nub超出范围......

import Data.List
  main=do
    line <- getLine
    putStrLn (List.nub words line)

我对如何克服这个问题一无所知.
