# Locked Up

```
My friend gave me a zip file with the flag in it, but the zip file is encrypted. Can you help me open the zip file?
```

(File(s): attachments/locked.zip)

The zip archive is password protected. However, something to note about password protected zip archives is that they are not 100% secure. Let's try running `strings` on the archive to see how much comprehensible data we can get from it, and then run `grep` to find the flag.

```
$ strings locked.zip | grep "hsctf"
hsctf{w0w_z1ps_ar3nt_th@t_secUr3}UT
hsctf{w0w_z1ps_ar3nt_th@t_secUr3}UT
```
