Cipher challenge Options

[Nyx]

Hey - was trying to get hold of Monkeyfriend. I'm Hazel. a maths grad from bristol now doing a crypto course, was hoping you could give me some advice on the crypto cipher challenge since you've completed it?

Have extracted the second link and have gone through the 7bit block, but am stuck at the 3rd block of hex, it doesn't transcribe to anything I've seen before?

Any help will be greatly appreciated

What games do you play here btw?

To anyone who's interested... the new cipher challenge is out. It's aimed at under 18's so is easier than the last one. For any of you who completed the last one, the registrations should be in the mail for the SANS/SOPHOS one, I'm booked in on the 21st Oct between 1400-2300.

Anyway the new challenge is available at:

https://cybersecuritychallenge.org.uk/cipher.html



Also I came across an old piece of uni work. A hybrid cipher that I developed as part of a university assignment, can be decrypted by hand without calcs or computers in around a minute (if you know it), however has never been cracked by human or software. Anyone decrypts it and I'll make some sort of shrine website to them.

[edit@ forums dont like my formatting, that should all be on one line]

[Edit 2: quickly did some more of the same cipher to make it easier]
