Encryption Challenges Explained

Some help for encryption challenges! :)
Now because people cheat, the answers have changed. I will re-do the challenges and edit the article accordingly. I am not entirely sure how accurate it is now, but will be updated soon. Thanks

I know alot of people find the Encryption challenges very hard so i will go over a few of them in this tut.
This is a walkthrough for some encs. No answers.

Enc1 -
This is simple enough - http://www.yellowpipe.com/yis/tools/encrypter/index.php

I Completed this challenge in a very weird way, I seperated the enc into pairs, and noticed a pattern.
This will help you:-

a=1
b=2
c=3
d=4
e=5
f=6
g=7
h=8
i=9
j=10
k=11
l=12
m=13
n=14
o=15
p=16
q=17
r=18
s=19
t=20
u=21
v=22
w=23
x=24
y=25
z=26

But you will notice that it still doesn't make any sense. Each letter - stands for another one. I was completely stumped
at this point and made my way to the forums, i noticed that nighthawk had posted:-
T*** **m* ** L** ** *** C*** *u* , *h** **** ** ****d *p *** *h*** , * ******d **i*!
And someone confirmed this of the right answer, just not the right punc.
You should now how enough letter values to make sense of the word.

This is alot like enc2, a letter for a letter. To get your letters though, divide. Use this to decrypt;):-

Also the number 27 - you will no what that is when you
have completed it.
Enc7 -
Use AIM Bot MD5 Library to decrypt this hash

Enc8 -
Based on a number system, Use an even number between 1 and 10 - eg using the number 22, i would minus 22 from
the first number, the next number i would add 22 and so on.
Also note that (-1) etc are not subtract values, they are negative numbers.

I left encs 3, 4 and 5 for you too try as you can now get to grips with how encryption challenges work. I hope i didnt
spoil these challenges for anyone.

Please comment as i intend to make some more articles.
