MD5加密和Bcrypt加密

一、MD5加密

//引入包
import org.springframework.util.DigestUtils;

@Controller
@RequestMapping("/resetpwd")
public class ResetpwdController {
	@RequestMapping("/resetpassword")
	@ResponseBody
	public int resetpassword(Member member, String username, String pwd) {
		//加密
		pwd = DigestUtils.md5DigestAsHex(pwd.getBytes());
		member.setPassword(pwd);
		int i = memberService.resetPasswordByUsername(member, username);
		return i;
	}
}

二、Bcrypt加密

由于现在彩虹表的出现，使得即使不可逆的MD5加密也变得伪可逆（大数据存储，然后查询）,所以采用更为安全的Bcrypt加密。
