java.security.InvalidKeyException:错误算法：AES或Rijndael必需错误

我在Java/Tomcat应用程序中遇到以下错误

尝试更改java JRM和JDK中的安全策略文件，但仍然相同

Tomcat控制台输出：

java.security.InvalidKeyException: Wrong algorithm: AES or Rijndael required

此函数产生错误：

public static synchronized byte[] encryptPrivateKey(
        ElGamalPrivateKey privateKey, byte[] hashedAnsBytes)
        throws NoSuchAlgorithmException, NoSuchPaddingException,
        InvalidKeyException, IllegalBlockSizeException,
        BadPaddingException, NoSuchProviderException, IOException {
    Cipher c = Cipher.getInstance("AES");
    SecretKeySpec key = new SecretKeySpec(hashedAnsBytes, "SHA256");
    c.init(Cipher.ENCRYPT_MODE, key);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ObjectOutput out = new ObjectOutputStream(bos);
    out.writeObject(privateKey);
    out.close();
    bos.close();
    byte[] pvtKeyBytes = c.doFinal(bos.toByteArray());
    return pvtKeyBytes;
}

有什么建议吗？有趣的是，这段代码在CentOS机器上运行良好。。。这个有Ubuntu。

你需要无限强度的加密。请注意，我只修复了许多编程错误，实际执行了哈希运算，实际将生成的密文写入流，并使用CBC模式和随机IV

public static synchronized byte[] encryptPrivateKey(
        ElGamalPrivateKey privateKey, byte[] hashedAnsBytes)
        throws GeneralSecurityException, IOException {
    Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
    MessageDigest digest = MessageDigest.getInstance("SHA256");
    final byte[] reallyHashed = digest.digest(hashedAnsBytes);
    System.out.println(reallyHashed.length);
    SecretKeySpec key = new SecretKeySpec(reallyHashed, "AES");
    SecureRandom rnd = SecureRandom.getInstance("SHA1PRNG");
    final byte[] iv = new byte[c.getBlockSize()];
    rnd.nextBytes(iv);
    IvParameterSpec spec = new IvParameterSpec(iv);
    c.init(Cipher.ENCRYPT_MODE, key, spec);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ObjectOutput out = new ObjectOutputStream(bos);
    out.write(iv);
    out.write(c.doFinal(privateKey.getEncoded()));
    out.close();
    bos.close();
    byte[] pvtKeyBytes = c.doFinal(bos.toByteArray());
    return pvtKeyBytes;
}

阅读此问题添加了以下库：import javax.crypto.*；导入javax.crypto.spec.*；导入java.security.*；而且真的成功了！谢谢我的朋友！不客气，不过在继续之前不要忘记尝试反转算法。
