Hiya,
I was wondering if anyone had any recourses for learning to make cryptography programs in Python? I managed to make a caesar cipher a while back in 2021 or ’22, but gave up when I got to affine lol – I want to try again with more experience!Hello,
You can buy or download:
Cracking code with Python, by Al Sweigart.Thank you! I’ll look into Cracking Code with Python – I also found “A book on Classical Cryptography” by Madness last night, and that seems really helpful. If anyone in the future wants to read it, you can find it here, or you could find it on the BOSS training recourses.
B Hi to all,
y I am thinking of posting
t some math questions and
e will ask for your answer
I along with your code used
n for solving it.
B You can use the language
i that you are familiar with
t I will give my answer and code
s using PARI-gp Calculator.(was just trying out – hope the above displays ok)
I am guessing this is the first in a series of coding challenges, so have at it! I think the setter is as interested in the code you write as in the arithmetical answer! I will hold off on publishing your solutions for a while so others can have a go. Harry
Hopefully a reasonably easy one to kick off with.
******************************************************************** Question #1
Find a number X that when divided by 4 leaves a remainder of 3 and
when divided by 5 leaves a remainder of 1 and when divided by 7 leaves a
remainder of 2 and when divided by 11 also leaves a remainder of 2 and
when divided by 17 leaves a remainder of 12. (with X > 5,000 & x < 50,000)—————– same question put another way
Find X
when X is divided by 4,5,7,11,17 and in turn leaves the remainders 3,1,2,2,12
(with X being greater than 5,000 but less than 50,000)For all questions: Give your code and the printout from it.
Will this get past the censor?
No! Did you think it would? Still pondering how best to release these. Think it would be best if replies on this thread came in two messages, one claiming to have made a solution, and which I can post without fear of spoilers, and a second with the solution in it that I can schedule for release when people have had a chance to try it. Then you can all crow, marvel or eat humble pie as appropriate. Fair? Harry
As you wish Harry: I claim to have made a solution!
Cool problem Bytes! I’m looking forwards to your next ones. How many will there be?
I have a solution, though not via any code!
