Because I'm building a website for cryptography learning, I decided to practice on examples of The non-Designer's Design Book.

Today is example on Page 16-17.

I've been busy build challenges for ACTF2019, and it's private so, there isn't anything.

Holy shit, why there's so many great things to do...

I've been busy build challenges for ACTF2019, and it's private so, there isn't anything.

Due to visit of my friend, I spent a lot of time playing with him. It's so relaxing, so I'm not productive this weekend. :D

I've complete a linear cryptanalysis attack towards simple a toy SPN cipher, I feel very veryyyyy happy!

Today I've been reading A Tutorial on Linear and Differential Cryptanalysis and finally finish reading it. I've found more interesting stuff like The Amazing King - Linear Cryptanalysis Tutorial The Amazing King - Differential Cryptanalysis Tutorial

Still there will be only some casual notes.

Let's write some notes takes while challenging my self learning.
