加密解密

1、BCrypt加密 ，比对

public static void main(String[] args) {
        String password = "123456";
        String hashpw = BCrypt.hashpw(password, BCrypt.gensalt());
        System.out.println("[hashpw]:"+hashpw);

        boolean matches = new BCryptPasswordEncoder().matches(password, hashpw);
        System.out.println("[matches]:"+matches);
    }

2、对称加密——base64加解密

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


public class EncryptUtil {
    /**
     * BASE64解密
     * @throws Exception
     */
    public static byte[] decryptBASE64(String key) throws Exception {
        return (new BASE64Decoder()).decodeBuffer(key);
    }

    /**
     * BASE64加密
     */
    public static String encryptBASE64(byte[] key) throws Exception {
        return (new BASE64Encoder()).encodeBuffer(key);
    }

    public static void main(String[] args) throws Exception {
        String ss = "123456";
        String encryptBASE64 = encryptBASE64(ss.getBytes());
        System.out.println(encryptBASE64);
        byte[] bytes = decryptBASE64(encryptBASE64);
        System.out.println(new String(bytes));
    }

 public static void main(String[] args) throws Exception {
        String ss = "123456";
        String encryptBASE64 =(new BASE64Encoder()).encodeBuffer(ss.getBytes());
        System.out.println(encryptBASE64);
        System.out.println(new String((new BASE64Decoder()).decodeBuffer(encryptBASE64)));
    }
}
