A processor supports an operating mode in which the default address size is greater than 32 bits and the default operand size is 32 bits. The default address size may be nominally indicated as 64 bits, although various embodiments of the processor ma…

16位的MD5加密和32位MD5加密的区别 MD5加密后所得到的通常是32位的编码,而在不少地方会用到16位的编码它们有什么区别呢?16位加密就是从32位MD5散列中把中间16位提取出来!其实破解16位MD5散列要比破解32位MD5散列还慢因为他多了一个步骤,就是使用32位加密后再把中间16位提取出来, 然后再进行对比而破解32位的则不需要,加密后直接对比就可以了 admin 的加密代码:16位加密:7a57a5a743894a0e32位加密:21232f297a57a5a743894a0e4a…

Nginx基本安全优化 1.调整参数隐藏Nginx版本号信息     一般来说,软件的漏洞都和版本有关,因此我们应尽量隐藏或清除Web服务队访问的用户显示各类敏感信息(例如:Web软件名称及版本号等信息),这样恶意的用户就很难猜到他攻击的服务器所用的是否是特定漏洞的软件,或者是否有对应的漏洞存在.   修改Nginx版本信息 [root@web02 ~]# vim /application/nginx/conf/nginx.conf http{ server_tokens off; } #我们在…
