Hello! There is a problem with an unknown company data center. Their existing solution is not efficient. Unfortunately, ex-main engineer Franciszek Warcislaw left the company. All they have is his login to internal company systems: franciszekwarcislaw and codename for solution upgrade operation: operationsluggishhamster . Can you help?
```
1. From the challenge description, it we realized that we had to look for this username: `franciszekwarcislaw`. Using [sherlock](https://github.com/sherlock-project/sherlock), we found out that there's a GitHub account [https://github.com/franciszekwarcislaw](https://github.com/franciszekwarcislaw).
2. This account has just 1 repository - `operationsluggishhamster`, consisting of a file `publickey.gpg`, which has a public key and a private key in it.
3. This part might be unintended. We base64 decoded the public key and we got an email id. In the intended solution, there was probably a different way to find this email.
```
Franciszek Warcislaw <[email protected]>
```
4. When you send an email to `[email protected]`, you get an automated response as follows:
```
This is my time for vacation! I will be back before 01.01.2021.
Ps. I do not work with hamsters anymore !
