Openssl等效命令来解密Java加密的base64文件aes

如何解决Openssl等效命令来解密Java加密的base64文件aes

通过引用this无法在Java中实现文件加密。 并加密后使用base64对文件进行编码（注意：我不想使用其他库，例如：Base64InputStream）

原始文件的内容为“ hello” .getBytes（UTF_8）;

使用以下命令无法解密（不包含base64数据）

openssl enc -nosalt -aes-256-cbc -d -in file.crypt -out file.txt -k abcdefghijklmop -md sha1

但是我无法向openssl提供base64编码的文件，请尝试以下命令：

openssl enc -nosalt -aes-256-cbc -d -base64 -in file.base64 -out file.txt -k abcdefghijklmop -md sha1

不良解密

base64 file.base64 | openssl enc -d -a -aes-256-cbc > decrypted -k abcdefghijklmop -md sha1

坏魔术数字

加密Java代码：

 static String password = "abcdefghijklmop";
 public static void encryptNew(String path) {
         try {
             Log.e("test","encrypt start " + path);
             FileInputStream fis = new FileInputStream(path);
            FileOutputStream fos = new FileOutputStream(path.concat(".crypt"));

            byte[] hash = new byte[0];
         byte[] keyAndIv = new byte[0];
          for (int i = 0; i < 3 && keyAndIv.length < 48; i++) {
                final byte[] hashData = array_concat(hash,password.getBytes(UTF_8));
                final MessageDigest md = MessageDigest.getInstance("SHA-1");
                hash = md.digest(hashData);
                keyAndIv = array_concat(keyAndIv,hash);
           }
           final byte[] keyValue = Arrays.copyOfRange(keyAndIv,32);
           final byte[] iv = Arrays.copyOfRange(keyAndIv,32,48);
           final SecretKeySpec secretKeySpec = new SecretKeySpec(keyValue,"AES");
           IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);

           Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
           cipher.init(Cipher.ENCRYPT_MODE,secretKeySpec,ivParameterSpec);
           CipherOutputStream cos = new CipherOutputStream(fos,cipher);
              int b;
            byte[] d = new byte[8];
              while ((b = fis.read(d)) != -1) {
                  cos.write(d,b);
              }
            cos.flush();
           cos.close();
             fis.close();
         } catch (Exception e) {
              e.printStackTrace();
        }
 encodeFile(path.concat(".crypt"));
     }

编码文件代码：

public void encodeFile(String path) {
          FileOutputStream stream = null;
          FileReader fr = null;
          try {
              stream = new FileOutputStream(path.concat(".base64"),true);
              fr = new FileReader(path);
          } catch (FileNotFoundException e) {
             e.printStackTrace();
         }
         try {
              BufferedReader br=new BufferedReader(fr);
              String line;
             while((line=br.readLine())!=null)
              {
                 String encoded = android.util.Base64.encodeToString(line.getBytes(),android.util.Base64.DEFAULT);
                 stream.write(encoded.getBytes());
             }
         } catch (IOException e) { e.printStackTrace(); } finally { try { fr.close(); stream.close(); } catch (IOException e) {e.printStackTrace();}}}
         

请在正确的openssl命令上建议解密java（aes加密-> base64编码）文件。
