Base64by32 #

Solution Walkthrough

1. The hint is in the name on this one. If we cat out the file, there are thousands of lines of base64 encoded text. We can write a quick for loop in bash to send the file content through 32 rounds of decoding and reveal the flag.

   #!/bin/env bash
   file="base64by32"
   content=$(cat "$file")
   
   for i in {1..32}; do
       content=$(echo "$content" | base64 -d)
   done
   
   echo $content
   

   

   Answer: flag{8b3980f3d33f2ad2f531f5365d0e3970}
