## What is  MicroSteemit

**MicroSteemit is developed based on the wechat micro application which is maintained by the tencent company.**

> wechat micro application is an application that doesn't need to be downloaded and installed. It implements the dream of "reach within reach", and users scan or search can open the micro application through the wechat application. It also reflects the idea of "running away", and users don't have to worry about installing too many apps. Micro Applications will be ubiquitous, readily available, without installing uninstall. Suitable for life service offline shops and non-new low-frequency conversion. The micro application can realize seven functions such as message notification, offline scan code and public number association. Among them, the user can realize the mutual jump between the wechat public account and the micro application through wechat association.

In a word , MicroSteemit is an application which can be used without downloading while chatting with friends in wechat easily. Just by scanning the MicroSteemit QR code  can we commodiously surf on  the steemit community.

**But now , the MicroSteemit is still in developed phase .Of course you also can test the project in the wechat application tool .See the github project in detail.**

## What feature(s) did you add?

- use aes Encrypt account password in the login page
- check account password whether is valid or not
- add operation module in the  back-end server
- identify whether the post has been approved or not and showing different icons

---

## How did you implement it/them?

- Encrypt account password with AES in the login page

  firstly set the 128 bit key and Hexadecimal number as the secret key offset

  ```
  // length of key is 16 of 128 bit. JUST for test the Decrypt
  const key = ''****************''
  // Hexadecimal number as the secret key offset. JUST for test the Decrypt
  const iv = '****************'
  ```

  Encrypt  the password

  ```
   Encrypt: function (word) {
      var srcs = fun_aes.CryptoJS.enc.Utf8.parse(word);
      var encrypted = fun_aes.CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: fun_aes.CryptoJS.mode.CBC, padding: fun_aes.CryptoJS.pad.Pkcs7 });
      return encrypted.ciphertext.toString().toUpperCase();
    },
  ```

- Decrypt account password in back-end server

  ```
  const aesDecrypt = function(data, secretKey, iv) {
      const cipherEncoding = 'hex'
      const clearEncoding = 'utf8'
      const cipher = crypto.createDecipheriv('aes-128-cbc',secretKey, iv)
      return  cipher.update(data,cipherEncoding,clearEncoding) + cipher.final(clearEncoding)
   }
  ```

- double checking the post permlink and author for identifying the active voters

  ```
  wx.request({
          url: 'https://api.steemjs.com/get_active_votes?author=' + author + '&permlink=' +permlink,
          method: 'GET',
          success: function (e) {
            console.log("request for active votes");
            if (e.statusCode == '200') {
              var activeVotes = e.data
              for (var vote in activeVotes) {
                if (activeVotes[vote].voter == currentAccount) {
                  console.log("I am one of the voters");
                  alreadyVotePermlink.push(permlink);
                  var newPostsData = that.data.postsData;
                  newPostsData[index].voteOrNot = 1;
                  that.setData({ postsData:newPostsData })
                  console.log(newPostsData)
                  break;
                }
              }
            }
          },
          complete:function(e){
        
          }
        })
  ```
