2. use it

   import fs from 'fs';
   
   import { FileEncrypt } from 'node-file-encrypt';
   
   let filePath = '/home/breeze/Develop/fast2array.tar'; // source file path
   let encryptPath = '';
   
   {   // encrypt file
       // to FileEncrypt can be passed 4 Arguments
       // filePath     - the path of the file that should be encrypted
       // outPath      - this is optional  - the Path for the encrypted file
       // fileEnding   - this is optional  - a custom fileEnding like '.myFile', default is '.crypt'
       // cryptFileName - this is optional - boolean if the filename should be hashed, default is true
       let f = new FileEncrypt(filePath);
       f.openSourceFile();
       f.encrypt('111111');
       encryptPath = f.encryptFilePath;
       console.log("encrypt sync done");
   }
   
   { // decrypt file
       fs.unlink(filePath, function() {});
       let f = new FileEncrypt(encryptPath);
       f.openSourceFile();
       f.decrypt('111111');
       console.log("decrypt sync done");
   }
   
   { // get original file name from encrypted file
       let f = new FileEncrypt(encryptPath);
       f.openSourceFile();
       console.log(f.info('111111'));
   }
   
   { // encrypt & decrypt file async
       let f = new FileEncrypt(filePath);
       f.openSourceFile();
       f.encryptAsync('111111').then(function() {
           encryptPath = f.encryptFilePath;
           console.log("encrypt async done");
           fs.unlink(filePath, function() {});
           let d = new FileEncrypt(encryptPath);
           d.openSourceFile();
           d.decryptAsync('111111').then(function() {
               console.log("decrypt async done");
           });
       });
   }
