前几天网上突然出现流言：某东发生数据泄露12G，最终某东在一篇声明中没有否认，还算是勉强承认了吧，这件事对于一般人有什么影响、应该怎么做已经有一堆人说了，所以就不凑热闹了，咱来点对程序猿来说实际点的，说一个个人认为目前比较安全的加密算法：Blowfish。 上代码之前，先说几点Blowfish加密算法的特点： 1. 对称加密，即加密的密钥和解密的密钥是相同的； Blowfish算法是一种对称的分组加密算法，算法核心在于子密钥生成，它将变长密钥扩展成总长4168Byte的子密钥数组。算法中使用了大量的子密钥，而子密钥又依赖于用户密钥，实际加/解密过程中使用的是更新后的子密钥数组，子密钥即P数组和S盒。Blowfish算法有一个核心加密函数:BF_En()，该函数的输人是64位明文信息，经过运算，以64位密文信息的形式输出。用Blowfish算法加密信息，需要两个过程:密钥预处理和信息加密。同样，解密亦需要两个过程，密钥预处理和信息解密。 Blowfish算法的源密钥――pbox和sbox是固定的，而我们要加密一个信息，需要自己选择一个key，用这个key对pbox和sbox进行变换，得到下一步信息加密所要用的key_pbox和key_sbox。解密亦是如此，由于Blowfish是对称加密算法，解密方在得到key后根据key生成解密所需的key_box和key_sbox。对同一个信息加密解密，选取的key的不同会导致密文的不同。因此，Blowfish算法的关键在于key的选择以及保密。 由于Blowfish算法采用变长密钥，这在给用户带来极大便利的同时也有隐患。由于算法加/解密核心在于密钥的选择和保密，但在实际应用中经常使用一些弱密钥对信息资源进行加密，导致存在着很大的安全隐患 接下来就是最重要的部分，Blowfish加密算法的实现：
package cn.bridgeli.encrypt;
public enum BlowfishManager {
BRIDGELI_CN("bridgeli_cn!@#$abc123_");
private BlowfishManager(String secret) {
this.blowfish = new Blowfish(secret);
}
private Blowfish blowfish;
public Blowfish getBlowfish() {
return blowfish;
}
/**
* 解密
* @param sCipherText
* @return
*/
public String decryptString(String sCipherText){
return this.getBlowfish().decryptString(sCipherText);
}
/**
* 加密
* @param sPlainText
* @return
*/
public String encryptString(String sPlainText){
return this.getBlowfish().encryptString(sPlainText);
}
public static void main(String[] args) {
String encryptString = BlowfishManager.BRIDGELI_CN.encryptString(10 + "");
System.out.println(encryptString);
String decryptString = BlowfishManager.BRIDGELI_CN.decryptString(encryptString);
System.out.println(decryptString);
}
}
这是对外的接口，使用起来非常简单，对用户很友好，下面是算法的具体实现：
