Solution to node. js AES encryption inconsistency

Recently, in an android game, the client and Nodejs server data are encrypted using AES. It is found that Nodejs and java are encrypted in different forms. After querying the N-long data, I found that the java client needs to encrypt the key again by using MD5 (I wiped it out). This is a stranger to encryption...

The code for nodejs and JAVA is pasted below.

JAVA:

                    String DEFAULT_CODING = "utf-8"               String decrypt(String encrypted, String seed)          [] keyb =         MessageDigest md = MessageDigest.getInstance("MD5"         [] thedigest =         SecretKeySpec skey =  SecretKeySpec(thedigest, "AES"         Cipher dcipher = Cipher.getInstance("AES"             [] clearbyte =                          String encrypt(String content, String key)          [] input =                    MessageDigest md = MessageDigest.getInstance("MD5"         [] thedigest =         SecretKeySpec skc =  SecretKeySpec(thedigest, "AES"         Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"                     [] cipherText =            ctLength = cipher.update(input, 0, input.length, cipherText, 0         ctLength +=                                                      len = hexString.length() / 2         [] result =            ( i = 0; i < len; i++             result[i] = Integer.valueOf(hexString.substring(2 * i, 2 * i + 2), 16                                   String parseByte2HexStr(         StringBuffer sb =           ( i = 0; i < buf.length; i++             String hex = Integer.toHexString(buf[i] & 0xFF              (hex.length() == 1                 hex = '0' +              }  

 

 

Node:

 crypto = require('crypto'=  cipher = crypto.createCipher('aes-128-ecb' cipher.update(data,'utf8','hex') + cipher.final('hex'=  cipher = crypto.createDecipher('aes-128-ecb' cipher.update(data,'hex','utf8') + cipher.final('utf8'
