# sim-exam
The data is split by level (`L1/`, `L2/`, `L3/`). Each level is a single `tar` archive, compressed with zstd, encrypted with AES-256-CBC (PBKDF2, 100000 iterations), and split into 10GB parts.
## Decrypt & extract
```bash
L=L1
cd $L
sha256sum -c sha256sums_$L.txt
cat sim_exam_$L.tar.zst.enc.part-* \
| openssl enc -d -aes-256-cbc -pbkdf2 -iter 100000 -pass pass:'<PASSWORD>' \
| zstd -d -T0 \
| tar -xf -
```
