## Installing Spentalkux
From the Brief we can see it is a python package.Downloading it and importing it gives the cipher text:```$ pip install spentalkux$ python>>> import spentulkuxHello.Can I help you?Oh, you're looking for something to do with *that*.My creator left this behind but, I wonder what the key is? I don't know, but if I did I would say it's about 10 characters.Enjoy this.Ztpyh, Iq iir'jt vrtdtxa qzxw lhu'go gxfpkrw tz pckv bc ybtevy... *ffiieyano*.

The code can be deciphered with a Vigenere cipher using the key: spentalkux
Then visit pastebin "https://pastebin.com/BCiT0sp6" and decode hex that forms an image
The image says to `look back into the past` which means the previous release of spentalkux
`pip install spentalkux==0.9`
It then gives another code
