Java实现url加密处理的方法示例
本文实例讲述了Java实现url加密处理的方法。分享给大家供大家参考，具体如下：
packagetest;
importjava.security.Key;
importjava.security.SecureRandom;
importjavax.crypto.Cipher;
importjavax.crypto.KeyGenerator;
importsun.misc.BASE64Decoder;
importsun.misc.BASE64Encoder;
publicclassThreeDES{
publicstaticStringcrypt(Stringcontent,Stringpassword,inti){
try{
KeyGeneratorgenerator=KeyGenerator.getInstance("AES");
generator.init(newSecureRandom(password.getBytes()));
Keykey=generator.generateKey();
generator=null;
if(i==1){
returngetEncString(content,key);
}
elseif(i==2){
returngetDesString(content,key);
}
}catch(Exceptione){
returnnull;
}
returnnull;
}
/**

*
*@paramstrMing
*@return
*/
privatestaticStringgetEncString(StringstrMing,Keykey){
byte[]byteMi=null;
byte[]byteMing=null;
StringstrMi="";
BASE64Encoderbase64en=newBASE64Encoder();
try{
byteMing=strMing.getBytes("UTF8");
byteMi=getEncCode(byteMing,key);
strMi=base64en.encode(byteMi);
}catch(Exceptione){
e.printStackTrace();
}finally{
base64en=null;
byteMing=null;
byteMi=null;
}
returnstrMi;
}
/**

*
*@paramstrMi
*@return
*/
privatestaticStringgetDesString(StringstrMi,Keykey){
BASE64Decoderbase64De=newBASE64Decoder();
byte[]byteMing=null;
byte[]byteMi=null;

}catch(Exceptione){
e.printStackTrace();
}finally{

}
returnstrMing;
}
/**

*
*@parambyteS
*@return
*/
privatestaticbyte[]getEncCode(byte[]byteS,Keykey){
byte[]byteFina=null;
Ciphercipher;
try{
cipher=Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE,key);

}catch(Exceptione){
e.printStackTrace();
}finally{

}
returnbyteFina;
}
/**

*

*@return
*/
privatestaticbyte[]getDesCode(byte[]byteD,Keykey){
Ciphercipher;
byte[]byteFina=null;
try{
cipher=Cipher.getInstance("AES");
cipher.init(Cipher.DECRYPT_MODE,key);
byteFina=cipher.doFinal(byteD);
}catch(Exceptione){
e.printStackTrace();
}finally{
cipher=null;
}
returnbyteFina;
}
publicstaticvoidmain(String[]args){
System.out.println(ThreeDES.crypt("bindMobile=13023130171&fenjihao=107","bbbbb",1));
System.out.println(ThreeDES.crypt("GT+F0fcFNGiq73/+FaX9pK9n9zqxwqz9sZ7MQdSp1BxWJXWn7EwnvniQpAOaGi0W","bbbbb",2));
}
