JAVA实现base64编码的三种实现方式

package cn.test;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

*/

//CommonsCodecBase64();
bouncyCastleBase64();
}

/**
* 使用JDK原生方法实现base64加密
*/
public static void jdkBase64() {
try {
BASE64Encoder encoder = new BASE64Encoder();
String jdkEncode = encoder.encode(src.getBytes());
System.out.println("JDKEncode-->" + jdkEncode);

System.out.println("JDKDecode-->" + new String(decoder.decodeBuffer(jdkEncode)));
} catch (IOException e) {
e.printStackTrace();
};
}
/**
* 使用commons.codecJAR的方式实现base64加解密技术
*/
public static void CommonsCodecBase64(){

System.out.println("CCDecode-->" + new String(CCDecode));

}
/**

*/
public static void bouncyCastleBase64(){

byte[] BCEncode = org.bouncycastle.util.encoders.Base64.encode(src.getBytes());
