只能破解难度级别较低的密码，这里使用了rockyou.txt为破解字典。试验成功破解获得密码password。但是目标破解文件还是无法解开，因为rar2john提取的hash文件太大了，尽然达到了53M，用现在的机器ETA要三天三夜 只好放弃了。

一、运行命令行，得到存储hash值的1.txt

./rar2john  ./first-file-plain.rar > ~/Downloads/1.txt

二、运行命令行

./john --list=formats

三、运行命令行

./john --format=rar --wordlist=~/Downloads/rockyou.txt ~/Downloads/1.txt

显示结果

Using default input encoding: UTF-8
Loaded 1 password hash (rar, RAR3 [SHA1 128/128 AVX 4x AES])

四、运行命令行，显示破解的密码。1.txt为被破解的hash值。

./john --show ~/Downloads/1.txt

显示结果，filename.rar:这就是密码明文:type:username:压缩文件目录

first-file-plain.rar:password:1::1 2
