在很多情況下，我們需要進行各種各樣的分析工作，這里為大家介紹一款密碼分析工具——Pipal。

Pipal是一款密碼分析工具，功能主要是進行密碼合集文件分析。說白了，就是對拿到的褲子中的密碼進行特征分析，找出其中的“各種最”，你沒看錯，這個東西功能就是這么簡單。。不過，工具的分析的速度還是很快的，同時也會從各個方面給出相應的分析結果。工具是作者為了滿足自己和朋友的需要寫的，現在被掛在了Git上面，這里我搬運過來，希望能為大家帶來幫助。

工具安裝

這個不用多說，git一下就好了：

git clone https://github.com/digininja/pipal.git /opt/pipal

運行環境

Pipal是運行在ruby下的，需要的ruby版本是1.9.x，其他環境會報錯無法運行，這點需要大家注意一下。

簡要介紹

工具本身帶的參數不多，我們可以使用./pipal.rb -?來查看幫助界面：

可用選項不多，也很簡潔。只說一下里面的top參數。top參數指定在所分析的密碼文件中位于最高頻率的前N位，N即為top的參數，比如我們需要待分析的密碼文件中的頻率前50的密碼，我們可以使用:

./pipal.rb --top 50 exmple.file

默認的top值為10.

使用很簡單，直接在命令后面跟上待分析的文件就可以了，比如我這里隨便分析一個文件

./pipal.rb 100W.txt

會顯示一個進度條

分析的速度也是比較快的。我這里找了一個100W左右的文件作為示例(9.4M)，大約用了不到5分鐘的時間就給出了分析結果。

根據上面的回顯我們大體就可以看出分析結果中所包含的部分，主要有密碼頻率TOP N，詞語頻率TOP N，密碼長度頻率分析(同時從序列和排名兩項給出)，更加創新的在terminal中給出了一個圖形化的分析(這點可是讓作者本人十分自豪的說)，等等還有很多，大家可以自行挖掘。
