# Warmups
Here are all my solutions to the `warmups` category, except for `Eighth Circle`
## Veebee
I use Windows, so I just ran it:
Just click through the second, and here we go:
Nice!
## Chicken wings
We have this encoded flag:
```
♐●♋♑❀♏????♍♏⌛?♐??????♍????♌?♍?♋?♌♎♍?♏❝
```
This is wingdings and we can decode this [here](https://lingojam.com/WingDing):
```
flag{e0791ce68f718188c0378b1c0a3bdc9e}
```
## Shoelaces
We have an image of shoelaces, I just ran `strings`, that's my instinct to check for a flag right away:
```
strings shoelaces.jpg | grep flag
flag{137288e960a3ae9b148e8a7db16a69b0}
```
## Car keys
```
We found this note on someone's key chain! It reads... ygqa{6y980e0101e8qq361977eqe06508q3rt}? There was another key that was engraved with the word QWERTY, too...
```
So this is definitely a `QWERTY` shift, I used [this]():
```
foak{6f980c0101c8aa361977cac06508a3de}
```
Just fix the prefix
```
flag{6f980c0101c8aa361977cac06508a3de}
```
## Buzz
```
You know, that sound that bumblebees make?
```
They `zzzzzzzz`, just use `7z x` on the file:
```
7z x buzz

## Pollex
We have an image:
```

Download the file below.

I was too lazy to switch to my `Kali` VM and run `file` etc. So I just used this [exif tool](http://exif.regex.info/exif.cgi):
## esab64
Try reconstructing it. `esab64` is kind of like `base64` isn't it?
```

b'_}e61e711106bd0db1b78efa894b1125bf{galf'

b'flag{fb5211b498afe87b1bd0db601117e16e}_'
```
There it is :)
