This is a dumb challenge. I'm sorry.

Steps

I downloaded the challenge file to kali quickly noticed the text is more likely encoded with base64.

Using cat base64by32 | base64 -d I see another base64 result. Next I executed cat base64by32 | base64 -d | wc -l and see a result of 6310. Doing that again, by running cat base64by32 | base64 -d | base64 -d wc -l the result continues to get smaller. This time the I see 4671. At this point, I believe the flag was base64 encoded 32 times. To find the flag, I used the below:

for i in {1..32}; do
    cat base64by32 | tr -d "\n" | base64 -d > temp && mv temp base64by32
done
cat base64by32

Flag: flag{8b3980f3d33f2ad2f531f5365d0e3970}
