用于解密java加密base64文件aes的Openssl等效命令

通过参考，我能够用java实现文件加密。 加密后，我用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）

使用下面的命令，我可以解密（没有base64数据）

但我无法向openssl提供base64编码文件，尝试了以下命令：

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

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, 0, 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, 0, b);
              }
            cos.flush();
           cos.close();
             fis.close();
         } catch (Exception e) {
              e.printStackTrace();
        }
 encodeFile(path.concat(".crypt"));
     }

请建议使用正确的openssl命令来解密java（aes加密->base64编码）文件。

在您的链接问题中@Topaco告知您他的评论“encryptfile（）和openssl（使用-base64选项）提供的结果不兼容。”此加密方法不适用于OpenSSL-由“坏幻数”明确指示。

encodeFile

方法无法可靠工作，因此可能无法使用OpenSSL（或任何其他工具）对结果进行解密。正确的方法是修复

encodeFile

方法。还请注意，从不含盐的密码中派生密钥是一个严重的安全风险。
