Matasano Crypto Challenge(s)

86JR · 28 Sep 2013 at 21:17

I did a search, no results, so thought you might be interested.

They email you challenges, for any skill level, in an attempt to help you understand code security by doing.

The only rule is please do not post the questions or answers on the public domain so not to ruin it for anyone else.

Has anyone had a go? Thoughts?

john_s · 2 Oct 2013 at 13:41

It sounded interesting, so I emailed them the other day, but haven't had a reply as yet.

Mailman86 · 2 Oct 2013 at 13:53

I've just sent them an email.

Phantom Shadow · 2 Oct 2013 at 18:45

Emailed them on sunday, stil no reply

john_s · 3 Oct 2013 at 14:00

I got an email last night with the first 8 challenges. Currently on no. 3...

Meekal · 3 Oct 2013 at 16:26

Emailed them just there, hopefully email me back before the weekend as i have some time off to do nothing :-)

Also got the email last night, got to number 4 - wanted to use something in python 3 so installed that and then completely broke what I was doing for number 3

Phantom Shadow · 4 Oct 2013 at 00:06

Has anyone got to number 4 on these yet? Managed to sort out my python problems and can't for the life of me see what I am doing wrong on number 4.

Number 3 works fine and I just use the same code for 4 but don't get anything readable

Just emailed them.

Really intrigued to see what the challenges are like. Will be doing them in C# (if possible!)

86JR · 8 Oct 2013 at 13:08

Any language is possible!

Yep. I'm doing them in C#, as time permits.

Now on number 6.

Thanks for confirming - really looking forward to giving these a try and hopefully learning something new!

I started these over summer. Got to the 3rd set of challenges. Work has taken over though.

john_s · 11 Oct 2013 at 13:46

I've started on the 8th.

No. 6 isn't quite right yet, so I need to go back and look at that, though I think it's the earlier code (from no. 3?) that needs tweaking to get it working properly.

duffers20 · 13 Oct 2013 at 19:18

Haven't received anything yet (sent email on the 7th). I hope they're still sending out the challenges as I'm really keen to give them a try!

john_s · 6 Jan 2014 at 13:33

Quick thread resurrection...

I finally managed to get the first set finished (including fixing the problem I suspected I had with no. 3) and submitted back over Christmas.

I've not received the next set of challenges yet though.

damn necro

- I just emailed them for the first set, I was going to get my Fortran on again!

john_s · 15 Jan 2014 at 08:59

I've not had the second set back yet.
