javascript - react-native AES Encryption matching Java Decryption algorithm -

the full code of java encryption/decryption algorithm:

public class aesencryptutil {      private static aesencryptutil instance = new aesencryptutil();     private string password = "123456";     private key key;     private cipher cipher;      public aesencryptutil(){         try {             keygenerator kgen = keygenerator.getinstance("aes");             kgen.init(128, new securerandom(password.getbytes()));             secretkey secretkey = kgen.generatekey();             byte[] encodeformat = secretkey.getencoded();             key = new secretkeyspec(encodeformat, "aes");             cipher = cipher.getinstance("aes");         } catch (exception e) {             e.printstacktrace();         }     }     public static byte[] encrypt(string content) throws exception {         byte[] bytecontent = content.getbytes("utf-8");         instance.cipher.init(cipher.encrypt_mode, instance.key);         byte[] result = instance.cipher.dofinal(bytecontent);         return result;     }     public static byte[] decrypt(byte[] content) throws exception {         instance.cipher.init(cipher.decrypt_mode, instance.key);         byte[] result = instance.cipher.dofinal(content);         return result;     }     public static string parsebyte2hexstr(byte buf[]) {         stringbuffer sb = new stringbuffer();         (int = 0; < buf.length; i++) {             string hex = integer.tohexstring(buf[i] & 0xff);             if (hex.length() == 1) {                 hex = '0' + hex;             }             sb.append(hex.touppercase());         }         return sb.tostring();     }     public static byte[] parsehexstr2byte(string hexstr) {         if (hexstr.length() < 1)             return null;         byte[] result = new byte[hexstr.length() / 2];         (int = 0; < hexstr.length() / 2; i++) {             int high = integer.parseint(hexstr.substring(i * 2, * 2 + 1), 16);             int low = integer.parseint(hexstr.substring(i * 2 + 1, * 2 + 2),                     16);             result[i] = (byte) (high * 16 + low);         }         return result;     }     public static string getnonce() {         string base = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789";         random random = new random();         stringbuffer sb = new stringbuffer();         (int = 0; < 16; i++) {             int number = random.nextint(base.length());             sb.append(base.charat(number));         }         return sb.tostring();     }     public static void main(string[] args) throws exception {         string content = "test";           system.out.println("content: " + content);           byte[] encryptresult = encrypt(content);           string encryptresultstr = parsebyte2hexstr(encryptresult);           system.out.println("encryptresultstr: " + encryptresultstr);           byte[] decryptfrom = parsehexstr2byte(encryptresultstr);           byte[] decryptresult = decrypt(decryptfrom);           system.out.println("decryptresult: " + new string(decryptresult));       } }  

i've tried many times , many ways match java algorithm, result different. module should use ? can me deal ? lot !

i found right way match 2 algorithm:

java part:

public static string encrypt() throws exception {         try {             string data = "123456";             string key = "1234567812345678";             string iv = "1234567812345678";              cipher cipher = cipher.getinstance("aes/cbc/nopadding");             int blocksize = cipher.getblocksize();              byte[] databytes = data.getbytes();             int plaintextlength = databytes.length;             if (plaintextlength % blocksize != 0) {                 plaintextlength = plaintextlength + (blocksize - (plaintextlength % blocksize));             }              byte[] plaintext = new byte[plaintextlength];             system.arraycopy(databytes, 0, plaintext, 0, databytes.length);              secretkeyspec keyspec = new secretkeyspec(key.getbytes(), "aes");             ivparameterspec ivspec = new ivparameterspec(iv.getbytes());              cipher.init(cipher.encrypt_mode, keyspec, ivspec);             byte[] encrypted = cipher.dofinal(plaintext);              return new sun.misc.base64encoder().encode(encrypted);          } catch (exception e) {             e.printstacktrace();             return null;         }     }      public static string desencrypt() throws exception {         string encrypted = encrypt() ;         try         {             string data = encrypted ;             string key = "1234567812345678";             string iv = "1234567812345678";              byte[] encrypted1 = new base64decoder().decodebuffer(data);              cipher cipher = cipher.getinstance("aes/cbc/nopadding");             secretkeyspec keyspec = new secretkeyspec(key.getbytes(), "aes");             ivparameterspec ivspec = new ivparameterspec(iv.getbytes());              cipher.init(cipher.decrypt_mode, keyspec, ivspec);              byte[] original = cipher.dofinal(encrypted1);             string originalstring = new string(original);             return originalstring;         }         catch (exception e) {             e.printstacktrace();             return null;         }     } 

react native part:

pre coding: npm install crypto-js

import cryptojs 'crypto-js' ; encryptfun() {     var data = "123456";     var key  = cryptojs.enc.latin1.parse('1234567812345678');     var iv   = cryptojs.enc.latin1.parse('1234567812345678');       var encrypted = cryptojs.aes.encrypt(       data,       key,       {iv:iv,mode:cryptojs.mode.cbc,padding:cryptojs.pad.zeropadding     });     console.log('encrypted: ' + encrypted) ;     var decrypted = cryptojs.aes.decrypt(encrypted,key,{iv:iv,padding:cryptojs.pad.zeropadding});     console.log('decrypted: '+decrypted.tostring(cryptojs.enc.utf8));   } 

the result :

encrypted: ak7+ux24ttbgftnandz9aq== decrypted: 123456 

i hope code someone:)
