MD5还广泛用于操作系统的登陆认证上,如Unix、各类BSD系统登录密码、数字签名等诸多方。如在UNIX系统中用户的密码是以MD5(或其它类似的算法)经Hash运算后存储在文件系统中。当用户登录的时候,系统把用户输入的密码进行MD5 Hash运算,然后再去和保存在文件系统中的MD5值进行比较,进而确定输入的密码是否正确。通过这样的步骤,系统在并不知道用户密码的明码的情况下就可以确定用户登录系统的合法性。这可以避免用户的密码被具有系统管理员权限的用户知道。MD5将任意长度的“字节串”映射为一个128bit的大整数,并且是通过该128bit反推原始字符串是困难的,换句话说就是,即使你看到源程序和算法描述,也无法将一个MD5的值变换回原始的字符串,从数学原理上说,是因为原始的字符串有无穷多个,这有点象不存在反函数的数学函数。所以,要遇到了md5密码的问题,比较好的办法是:你可以用这个系统中的md5()函数重新设一个密码,如admin,把生成的一串密码的Hash值覆盖原来的Hash值就行了。

  为什么不是爱情童话?抱歉我要用很世俗的眼光来分析男女主人公的感情,但是我一贯不相信一个人一生非另一个人不可,除非那个人的意义上升到了另一个高度。 Jamal 的理想主义在那种社会环境下意味着他始终需要一个精神寄托。小的时候是那个男明星, Jamal 为了他的签名可以跳进粪坑。而母亲死后, Jamal和哥哥一直在过着颠沛流离的日子,兄弟感情又不是纯友爱,只能说又爱又恨的。他唯一的朋友,他生命中唯一美好的事物就是 Latika 了。即使失散多年 Jamal 也忘不了 Latika ,因为寻找她是他生命的主要意义,是他活着的理由。因此,我认为这种近似强迫症的不现实的坚持其实是可能的,有着现实意义,不是童话。有人说 Freida Pinto 过于漂亮,我很同意。 Jamal 认为 Latika 是世上最美的女人,而 Pinto 也差不离了;如果 Latika 其实没有那么漂亮,就更能体现出她对于 Jamal 的精神意义。

“The arguments have devolved over three or four years of bitter debate, the principles are real and they are important to preserve, but a lot of the drama has nothing to do with principles anymore. A lot of this debate is now more about hurt feelings. It’s about bruised egos. It’s about things that were said that can’t be unsaid, insults that were exchanged, and personalities and ego.”

第八次矛盾,也是全剧的高潮,面对着一个为了拉提卡,用尽一切方法都想要找回她的亲弟弟,他要怎样做?影片中第一次,出现了一个落寞的萨利姆形象,从前的他,都是意气风发地去干自己想要干的事,但当看到弟弟出现在了电视上,他开始怀疑了,自己所有的人生信仰瞬间崩塌。他想要出人头地,他想要挣钱,他想要当百万富翁,同时,如果没有拉提卡的介入,这对兄弟原本是一对形影不离的好拍档,他们一起逃跑,一起在火车上偷东西,做小生意,为了生存,一起在泰姬陵当导演,偷人家的鞋子。我不相信萨拉姆不记得这一切,在他眼中,这个弟弟是一个很重要的存在,他虽然时常欺负他,做一些小恶作剧,但他深爱着唯一的弟弟,他想让他快乐,让他不要与黑手党扯上关系,于是,他一次又一次选择了放开贾马尔的手,实际上是在给他生的机会,快乐的机会,但直到那一刻,萨利姆突然明白,原来,对于贾马尔而言,所有的人生追求并不是过上富足的生活,并不是有一个百万富翁的哥哥,而是拉提卡。那一刻,萨利姆一定在内心嘲笑自己,怎么一直都不了解弟弟的需求,原来自己做的一切都是错的。于是,他安静地说了下面这段话:

第二次矛盾,当萨利姆和贾马尔被诱拐到了马曼所开的“孤儿院”时,萨利姆凭借自己的勇敢和聪慧,成为了孩子王,也同时被马曼看上,选择为他自己的爪牙。在萨利姆把一群流浪儿管理得服服帖帖的时候,他与广大的孤儿产生了不可避免的矛盾,而与贾马尔的矛盾也是必然的。编剧在设计他们之间的矛盾时,使用了拉提卡,把她放到了矛盾的冲突点和制高点上,使拉提卡再一次成为贯穿主线的人物。萨利姆想要把婴儿交给拉提卡带,说:“拉提卡,今天你负责带他”,拉提卡说:“我不带”,这时候,萨利姆的权威受到了质疑,作为一个小头头,他一定要让拉提卡服从,于是他说:“抱着吧,这是为你好,有小孩可以要双份。”冲突产生了,萨利姆的命令和拉提卡的意愿产生了矛盾,这时出面的,就是既喜欢拉提卡,又是萨利姆弟弟的贾马尔,他在这两人中, 始终保持着微妙的关系。贾马尔说:“她说了不想带。”当时的贾马尔,决对不是萨利姆的对手,而且萨利姆也必须以牺牲弟弟的利益,才能在孩子中树威,所以,他斩钉截铁地说:“你少说话,贾马尔,接着,不然我把他扔了。”这样,迫使拉提卡接受了萨利姆的建议,再一次的争锋中,萨利姆的名利观战胜了兄弟情。

Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.

Bitcoin Cash was launched in August 2017, as a direct response to small block sizes on the Bitcoin code. 1MB block sizes were not meeting the demand of the growing community, so a group of dissatisfied crypto enthusiasts decided to create a ‘hard fork’ of the Bitcoin blockchain, with an increased 8MB block size. No one person currently takes credit for the token’s creation; rather it is attributed to a de-centralized group of developers.
