Question

我想将我的密钥库对象从我的服务器传输到客户端应用程序：

我正在做以下事情：

 response.reset();
 response.setBufferSize(10240);
 response.setContentType(contentType);
 response.setHeader("Content-Length", String.valueOf(keystoreFile.length()));
 response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
 BufferedInputStream input = null;
 BufferedOutputStream output = null;
 try{


 input = new BufferedInputStream(new FileInputStream(keystoreFile), DEFAULT_BUFFER_SIZE);
 output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);

 output.write(KeyStoreUtil.getFileByteArray(input));
 }finally{
     input.close();
     output.close();
 }

但是文件在客户端损坏并且在获取密钥库时收到错误：

java.io.EOFException
        at java.io.DataInputStream.readInt(DataInputStream.ja
        at com.sun.crypto.provider.JceKeyStore.engineLoad(Jce
        at java.security.KeyStore.load(KeyStore.java:1214)

实际上我看到的是，文件正在创建：如果我从命令提示符运行命令：

keytool -list -storetype jceks -keystore aeskeystore.jck
Enter keystore password:

我收到错误：

keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

getFileByteArray如下：

public static byte[] getFileByteArray(InputStream fileInputStream) {
    if (fileInputStream != null) {
        int readLine = 0;
        byte[] data = new byte[16384];
        ByteArrayOutputStream fileBuffer = new ByteArrayOutputStream();

        try {
            while ((readLine = fileInputStream.read(data, 0, data.length)) != -1) {
                fileBuffer.write(data, 0, readLine);
            }

            return fileBuffer.toByteArray();
        } catch (IOException e) {
            logger.error("Error occurred while reading keyfile::::"
                    + e.getMessage());
        }
    }
    return null;
}

无法发送密钥
