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：

package test;
import java.security.key;
import java.security.securerandom;
import javax.crypto.cipher;
import javax.crypto.keygenerator;
import sun.misc.base64decoder;
import sun.misc.base64encoder;
public class threedes {
  public static string crypt(string content,string password,int i){
    try {
      keygenerator generator = keygenerator.getinstance("aes");
      generator.init(new securerandom(password.getbytes()));
      key key = generator.generatekey();
      generator = null;
      if(i == 1){
        return getencstring(content,key);
      }
      else if(i == 2){
        return getdesstring(content,key);
      }
    } catch (exception e) {
      return null;
    }
    return null;
  }
  /**
   * 加密string明文输入,string密文输出
   *
   * @param strming
   * @return
   */
  private static string getencstring(string strming,key key) {
    byte[] bytemi = null;
    byte[] byteming = null;

    base64encoder base64en = new base64encoder();
    try {
      byteming = strming.getbytes("utf8");
      bytemi = getenccode(byteming,key);

    }
    return strming;
  }
  /**
   * 加密以byte[]明文输入,byte[]密文输出
   *
   * @param bytes
   * @return
   */
  private static byte[] getenccode(byte[] bytes,key key) {
    byte[] bytefina = null;
    cipher cipher;
    try {

      cipher.init(cipher.encrypt_mode, key);

    } catch (exception e) {
      e.printstacktrace();
    } finally {

    }
    return bytefina;
  }

  }
  public static void main(string[] args) {
    system.out.println(threedes.crypt("bindmobile=13023130171&fenjihao=107", "bbbbb", 1));
    system.out.println(threedes.crypt("gt+f0fcfngiq73/+fax9pk9n9zqxwqz9sz7mqdsp1bxwjxwn7ewnvniqpaoagi0w", "bbbbb", 2));

}
