As a VIM lover, have you ever wondered the possibility of using vim bindings to edit commands in your shell? Or perhaps you’re curious about how to manage lengthy commands effortlessly, without getting lost in endless flag combinations? If so, buckle up! You’re in for a treat! In this blog post, we will introduce you to an indispensable yet often overlooked component of the Bash environment - the…
Bijections are fun to look at and amusing especially to cryptographers, can you spot out one here?
Can array based initialization of mersenne twister which is used in current libraries be reversed to get the seed (any 1-19937 bit quantity)
One can guess all the future outputs of a random number generator once they recover the state, but how feasible is it to recover the past state of pseudo random number generator given its present state?
Numpy uses plain old implementation of Mersenne Twister as the default pseudo random number generation.
Challenges are the way to get quick hands on tasks and challenges made by me. There will be plenty of hands-on experience through a guided set of static challenges.
This is an open-sourced website hosted on github pages! If you wish to contribute or have a cool idea to share or even a cool challenge which can be put up as an assignment, this is the correct page you are looking at.
Welcome to my personal blog about cybersecurity and computers in general where I host cool challenges (aka assignments) too
