Decryption Challenge II

Seeing that you guys cracked the first code pretty easily, I’m giving a second code, obviously difficult than the previous one. I found it quite difficult to crack but I don’t know about the rest of you.

The following scriptures were actually found in the diary of a 16th century englishman. You have to decode this. It decrypts (obviously) into English.

Frankly speaking I wasen’t able to decrypt it without looking at the hint.

Mail me at abhijit89@gmail.com for a big hint

Best of Luck!

Hopefully you’ll find this more time consuming than the previous one.

PS: Please don’t check up the solutions from anywhere.

Also please don’t mail solutions on the blog. Mail them to me (again at abhijit89@gmail.com) if you manage to solve it.

Techedge was at Birla Vidya Niketan on 3 August , the round I was pretty simple, but the second question for round II involved GRAPHICS for which we required the “help file”.I apologise for posting the questions so late, and thanx Souvik for ur help.the questions are :

Round I

Question 1:

Make a program which sort a 2D matrix according to the following example

9 1 4 2 1 2 3 4

11 10 16 8 5 6 7 8

5 12 17 15 à 9 10 11 12

6 3 13 14 13 14 15 16

Question 2:

Write a menu driven program for encrypting, decrypting and splitting files.

Round II

Question 1:

Write a program to make an asterisks bounce on the screen such that it moves with variable velocity. The asterisks should increase velocity on hitting the edges. Also the initial acceleration and initial velocity should be user input.

Question 2:

Make an analog clock with least count=1 second(using graphics complete with hour hand, minutes hand and the seconds hand)

Answer these if you dare!!!

1)What is DoCoMo?What relation does it have with imode? (2)

2)How much cache does intel extreme edition have(only l2 and l3)? (2)

3)Who is John T Chambers?How can you relate Gordon Moore to Jerry Sanders in respect to business/academics except that their companies are rivals? (2)

4)Who is the chief programmer of id software and who is the ceo?In what other way the chief programmer related to the company? (2)

5)What is Dark Matter?What do you do with a wumpus? (2)

For quizers

A Decryption Challenge

This cipher uses a common key for encryption and decryption which is kept secret and is known to only the sender and reciever of the message.

The following is the cipher text encrypted using the key “vigilance”

“hmkb xe bp xpmylly rxiiqto lt fgzzv”

This when decrypted reads

“meet me on tuesday evening at seven”

So the challenge is to decrypt the following text which has also been encrypted using the key “vigilance”

“opoa nicjim qy kllygh vtvplbrv gdxnmc aaf ava sioe oa pzeoa naeqp”

Best of Luck!

Sessions@Exun : Advanced PHP by Mukul Sabharwal

Hello,

Once again. I invite you to another session of PHP. As usual everybody is welcome … but with a few prerequisites : simple programming knowledge + basic PHP syntax which we covered last time in the session.

Sessions@Exun Website has a slightly more refined version of the above text.

The tentative date is 13th August, this coming friday. We’ll work with time conflicts, but this day seems perfect. Let’s stick to it if we can.

The scheduled time is 1PM. We’d like to wrap up early, so we start early.

However, comment to tell us your problems.

Thanks,

Mukul

P.S. – string Advanced; Advanced = “Basic PHP … beyond syntax”;
