+# My use cases for CyberChef
+
+### Formatting MAC addresses
+
+Cisco seems to require a different format for every solution they have. I use this almost daily, so change the format of one or multiple MAC addresses.
+
+Input:
+`aa-aa-aa-bb-bb-bb`
+
+Output:
+```
+aaaaaabbbbbb
+AAAAAABBBBBB
+aa-aa-aa-bb-bb-bb
+AA-AA-AA-BB-BB-BB
+aa:aa:aa:bb:bb:bb
+AA:AA:AA:BB:BB:BB
+aaaa.aabb.bbbb
+AAAA.AABB.BBBB
+```

+
+**Tipp**: the easiest way to change the format of multiple formats, is to choose the desired format, input 1 MAC address per line, and remove the empty lines with a `Find/ Replace` operation with the following regex search `^(?:[\t ]*(?:\r?\n|\r))+`.

+
+### Looking up Linux permissions
+
+Simple way to switch between various representations and shows the permissions.
+
+Input:
+`-rw-r--r--`
+
+
+Output:
+```
+Textual representation: -rw-r--r--
+Octal representation:   0644
+File type: Regular file
+
+ +---------+-------+-------+-------+
+ |         | User  | Group | Other |
+ +---------+-------+-------+-------+
+ |    Read |   X   |   X   |   X   |
+ +---------+-------+-------+-------+
+ |   Write |   X   |       |       |
+ +---------+-------+-------+-------+
+ | Execute |       |       |       |
+ +---------+-------+-------+-------+

+
+### Working with IT subnets
+
+This function makes my life easier. It shows me the general network information and the range of a IP addresses for a subnet.
+
+Input:
+
+`10.121.10.8/28`
+
+Output:
+
+```
+Network: 10.121.10.8
+CIDR: 28
+Mask: 255.255.255.240
+Range: 10.121.10.0 - 10.121.10.15
+Total addresses in range: 16
+
+10.121.10.0
+10.121.10.1
+10.121.10.2
+10.121.10.3
+10.121.10.4
+[...]
+```

+
+### Converting blog titles to an URL-friendly format
+
+I've created a small 'Recipe' to format my titles to URL/ text file friendly formats.
+
+Input:
+
+`My use cases for CyberChef`
+
+Output:
+
+`my-use-cases-for-cyberchef`
+
+[Try it yourself](https://baked.brrl.net/#recipe=Find_/_Replace\(%7B'option':'Regex','string':'-'%7D,'',true,false,true,false\)Find_/_Replace\(%7B'option':'Regex','string':'%20%20'%7D,'%20',true,false,true,false\)Find_/_Replace\(%7B'option':'Regex','string':'%5C%5C.'%7D,'',true,false,true,false\)Find_/_Replace\(%7B'option':'Regex','string':'%20'%7D,'-',true,false,true,false\)To_Lower_case\(\)&input=TXkgdXNlIGNhc2VzIGZvciBDeWJlckNoZWY)
+
+### Finding the difference in text
+
+I only use this function for small configuration files or texts. For larger ones, I prefer vimdiff or Notepad++.
+
+[Try it yourself](https://baked.brrl.net/#recipe=Diff\('%5C%5Cn%5C%5Cn','Character',true,true,false,true\)&input=SSBzd2VhciwgdGhlcmUgaXMgbm90aGluZyBtaXNzaW5nLgoKSSBzd2VhciwgdGhlcmUgaXMgbWlzc2luZy4)
+
+### Changing chars to upper/lower case
+
+I rarely use this function, but it has its use cases. Some passwords contain many characters, that can be difficult to differentiate, like `l`, `I`, `1`, `O`,`0`, and so on. I tend to use this feature if I only have 1 more try left, just to make sure.
+
+And I know that copy+paste exists, but that isn't always an option.
+
+[Try it yourself](https://baked.brrl.net/#recipe=To_Upper_case\('All'\)&input=VEhsU18xU19hX1A0UzV3b3JE)
+
+### Adding or remove line numbers
+
+This is self-explanatory. I do not need this feature that often, but comes in handy from time to time.
+
+### Hashing things
+
+If you need a hash of a string or file, CyberChef offers many algorithms. SHA, MD, bcrypt, and so on.
+
+[Try it yourself](https://baked.brrl.net/#recipe=SHA2\('512',64,160\)&input=VEhsU18xU19hX1A0UzV3b3JE)
+
+### Generating QR codes
+
+I use it monthly to generate the QR code for our guest WLAN. Add `WIFI:S:MySSID;T:WPA;P:TH1S_P455W0RD;;` into the input field and it generates the QR code for you. I regularly use it for URLs too.
+
+[Try it yourself](https://baked.brrl.net/#recipe=Generate_QR_Code\('PNG',8,2,'Medium'\)&input=V0lGSTpTOk15U1NJRDtUOldQQTtQOlRIMVNfUDQ1NVcwUkQ7Ow)
+
+### Generating dummy texts / Lorem Ipsum
+
+Really helpful to generate dummy text for all kinds of mock-ups.
+
+[Try it yourself](https://baked.brrl.net/#recipe=Generate_Lorem_Ipsum\(3,'Paragraphs'\))
+
+### Various utilities
+
+I won't go into too much detail since it is fairly self-explanatory. Sorting lines, convert masses or distances, remove white spaces, Find/Replace, find unique strings, converting hexdumps, converting date/time formats, and so many more.
+
+## Conclusion
+
+CyberChef has become a great tool with many use cases. It is more the quick and dirty solution, but this is often all I need.
