| 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 - | |
