you just have to unzip each zip file and use the base64 decoded name of the file as its passwordthis script does just one stepand it can be used in a whileafter a some time the only remaning file in the directory will be the flag
```x=$(ls Recurzip)cd Recurzip#echo "$x"unzip -P $(echo "$x" | cut -d'.' -f1 | base64 -d) "$x"if [ $(ls | wc -l) -gt 1 ]then        rm "$x"ficd -~```
