我有这种加密方法：

private byte[] encrypt(byte[] data) throws NoSuchAlgorithmException,NoSuchPaddingException,InvalidKeyException,IllegalBlockSizeException,BadPaddingException {
    Cipher cipher = Cipher.getInstance("RSA/ECB/pkcs1Padding");
    cipher.init(Cipher.ENCRYPT_MODE,myPublicKey);
    ByteArrayInputStream input = new ByteArrayInputStream(data);
    ByteArrayOutputStream output = new ByteArrayOutputStream();
    byte[] buffer = new byte[64];
    int bytes;
    ByteArrayOutputStream aux;
    try {
        while ((bytes = input.read(buffer)) != -1) {
            aux = new ByteArrayOutputStream();
            aux.write(buffer,bytes);
            byte[] fragment = aux.toByteArray();
            byte[] encryptedFragment = cipher.doFinal(fragment);
            output.write(encryptedFragment);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    byte[] result = output.toByteArray();
    return result;
}

还有一个用于解密：

public static String decrypt(byte[] data) throws NoSuchPaddingException,NoSuchAlgorithmException,BadPaddingException,IOException {
    Cipher cipher = Cipher.getInstance("RSA/ECB/pkcs1Padding");
    cipher.init(Cipher.DECRYPT_MODE,myPrivateKey);
    int bitLenght = ((java.security.interfaces.RSAPrivateKey) privateKey).getmodulus().bitLength();
    int blockSize = bitLenght / 8;
    byte[] buffer = new byte[blockSize];
    int bytes;
    byte[] decrypted;
    ByteArrayOutputStream aux;
    ByteArrayInputStream input = new ByteArrayInputStream(data);
    ByteArrayOutputStream output = new ByteArrayOutputStream();
    while ((bytes = input.read(buffer)) != -1) {
        aux = new ByteArrayOutputStream();
        aux.write(buffer,bytes);
        byte[] fragment = aux.toByteArray();

        byte[] decryptedFragment = cipher.doFinal(fragment);
        output.write(decryptedFragment);
    }
    decrypted = output.toByteArray();

    return new String(decrypted);
}

但是我遇到了这个异常：

  

javax.crypto.BadPaddingException：解密错误

正如我所看到的，我已将密码配置为具有相同的pkcs1Padding，所以我不知道为什么会收到该错误。

我已如下创建我的私钥：

openssl genrsa -out myPrivateKey.key 2048

和公众一个：

openssl rsa -in myPrivateKey.pem -pubout -out myPublicKey.key

据我所见，它们都是pkcs1，实际上我的私钥以-----BEGIN RSA PRIVATE KEY-----开头。

我想念什么？

注意：我也尝试过blockSize = 64，结果也一样。
