# Verify (Easy)

This one will be pretty quick. The challenge gives us 3 objects.

We use the checksum.txt to find sha256 hash as a file in "files". We'll need to use grep for this.

```
sha256sum files/* | grep 467a10447deb3d4e17634cacc2a68ba6c2bb62a6637dad9145ea673bf0be5e02
```

Doing this, we get the file name. Once we find that, it's just another command before finding the flag.

```
./decrypt.sh files/c6c8b911
```
