加密PBEWithMD5AndDES在j2me [英] encrypt PBEWithMD5AndDES in j2me

问题描述

我正在尝试让这段代码在j2me
上工作（它正在开发一个java程序）
但尚未在j2me中

  public static String generate（String plaintext，String passphase）throws异常{
 try {
 PBEKeySpec pbeKeySpec = new PBEKeySpec（passphase.toCharArray（））; 
 PBEParameterSpec pbeParamSpec; 
 SecretKeyFactory keyFac; 
 // Salt 
 byte [] salt = {（byte）0xc8，（byte）0x73，（byte）0x61，（byte）0x1d，（byte）0x1a，（byte）0xf2，（byte） 0xa8，（byte）0x99}; 
 //迭代计数
 int count = 20; 
 //创建PBE参数集
 pbeParamSpec = new PBEParameterSpec（salt，count）; 
 keyFac = SecretKeyFactory.getInstance（PBEWithMD5AndDES）; 
 SecretKey pbeKey = keyFac.generateSecret（pbeKeySpec）; 
 //创建PBE密码
密码pbeCipher = Cipher.getInstance（PBEWithMD5AndDES）; 
 //用键和参数初始化PBE密码
 pbeCipher.init（Cipher.ENCRYPT_MODE，pbeKey，pbeParamSpec）; 
 //我们的cleartext 
 byte [] cleartext = plaintext.getBytes（）; 
 //加密明文
 byte [] ciphertext = pbeCipher.doFinal（cleartext）; 
返回密文; 
} catch（Exception ex）{
 throw new Exception（ex.getMessage（））; 
} 
} 
  

我发现这个lib
http://www.bouncycastle.org/java.html

$ b $重要的是，我找到一个可以使用PBEWithMD5AndDES加密的j2me的方法

任何人都知道解决方案？

编辑添加额外的信息

当我尝试将以上代码添加到移动项目
以下类是不确认（不包括在j2me中）

  PBEKeySpec 
 PBEParameterSpec 
 SecretKeyFactory 
  

所以我需要一个允许我使用PBEWithMD5AndDES
对纯文本进行编码的包，任何人都知道这样一个与j2me兼容的包？ / p>

解决方案

很多可能会出错应用原语时，您应该使用 Jasyp t 。

i'm triing to get this code to work on j2me (it is working a java program) but not yet in j2me

    public static String generate(String plaintext, String passphase) throws Exception {
        try {
            PBEKeySpec pbeKeySpec = new PBEKeySpec(passphase.toCharArray());
            PBEParameterSpec pbeParamSpec;
            SecretKeyFactory keyFac;
            // Salt
            byte[] salt = {(byte) 0xc8, (byte) 0x73, (byte) 0x61, (byte) 0x1d, (byte) 0x1a, (byte) 0xf2, (byte) 0xa8, (byte) 0x99};
            // Iteration count
            int count = 20;
            // Create PBE parameter set
            pbeParamSpec = new PBEParameterSpec(salt, count);
            keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
            SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);
            // Create PBE Cipher
            Cipher pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");
            // Initialize PBE Cipher with key and parameters
            pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);
            // Our cleartext
            byte[] cleartext = plaintext.getBytes();
            // Encrypt the cleartext
            byte[] ciphertext = pbeCipher.doFinal(cleartext);
            return ciphertext;
        } catch (Exception ex) {
            throw new Exception(ex.getMessage());
        }
    }

i found this lib http://www.bouncycastle.org/java.html

the important thing is that i find a method for j2me that can encrypt using PBEWithMD5AndDES

anyone know the solution?

edit adding extra info

when i try to add the above code to a mobile project following classes are not recognized (not included in j2me)

    PBEKeySpec
    PBEParameterSpec
    SecretKeyFactory

so i need a package that allows me to encode plain text using PBEWithMD5AndDES anyone know such a package compatible with j2me?

thx for the replies so far

解决方案

A lot can go wrong when applying a primitive, you should use Jasypt.
