v0lt

v0lt

Rawsec's CyberSecurity Inventory

v0lt is an attempt to regroup every tool I used/use/will use in security CTF, Python style.A lot of exercises were solved using bash scripts but Python may bemore flexible, that's why.Nothing to do with Gallopsled. It's a toy toolkit, with small butspecific utils only.

This project is not maintained anymore, since the utils themselves are small enough to work almost all the time without the need of maintaining anything. Feel free to submit PRs if you want however :)
