There is such interesting, matasano cryptography challenge.
Lets do it, lets use for productivity Cloud.Math, nice cloud platform. You probably have to registrate there, but you will not regret it – fully fledged, very powerful mathsuite+python.. it cant get any better.
Anyway, here is solutiun to first part. And it is good to understand, that First we have string, which is represented by encoded hex bytes. each hex byte – corresponds to character. Coverting all hexes to string we get “”
Afterward we take this string and encode it to base64, various ways to do it.
Also, i am back and will write mostly in english from now on, and mostly about cryptography or stuff i dig in university.
