Read the terms and conditions, only for UK, so I don't like it.

The idea is nice, but then restricting it, not so much. It's almost like having open source only for the US.

Kind of. The real purpose of the contest is for GCHQ to recruit talent, so it makes sense that they restrict it local to them.
However, that still doesn't stop anyone from trying the challenges just for the fun of it.

How so? If you are looking for talent, and people to add to your team, (which it says) placing restrictions will only prevent some talent being eligible.

Judging from the terms and conditions it's set up at least partially as a sweepstakes, so there are some legal hoops they have to jump through: "Winners will be randomly chosen by GCHQ..." etc.

RSA Public Key token

([msg=77458]see RSA Public Key token[/msg])

(merged)

Hi all,

I am trying to work through the GCQH Can you Find It challenge. I have completed one, but two I'm having a little trouble. A simple google search and I've found the answer, but this is missing the point! I want to do it, and understand what I'm doing...

So those who haven't done it, look away now *SPOILER ALERT*

.

On Challenge two, I am given a private key to download. I understand this contains several parts, including the private key, and modulus.

I have extracted the parts using openssl, and now have several parts in hex. What I need to do it convert to ASCII (According to a site) and see letters appear.

My first question is, how did they know to convert to ASCII? Is this a standard task to see the passcode? Is this because one of the primes is larger then the other?

My second q is, how do I convert to ascii? I was given a site, but I wanted to find a tool \ method I could use, but ended up using the site without any luck!

I have read up on RSA public & private keys, but still not getting it :(
