MD5 Hashing Box v0.5

i've started this tool some while ago and here is it done now x)

it still need some improvements but not now since i'm preparing for the big exam :D damn i can't believe i'm doing it :p anyway have fun with this tool :)

for the snapshot see the update!!

n! aka Factorial

So i have just finished that mathematic course wich uses the factorial Probabilities and/or Combinations and Permutations (Damn i still don't understand it very well x)) and i have decided to code an asm program that can calculate factorial wait! do you know what is it?! well Factorial is means to multiply a series of descending natural numbers. ( symbol: ! )
For exemple:
1! = 1 why? cuz they had generally agreed that 0! = 1
2! = 2*1 = 2
3! = 3*2*1 = 6  
4! = 4 × 3 × 2 × 1 = 24  
7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

you wan't more?  

you think they're large see the next ones :) i counted some of themusing calc of wind0ws x)

100! = 9,3326215443944152681699238856267e+157

200! = 7,8865786736479050355236321393219e+374

3000! = 4,1493596034378540855568670930866e+9130

4000! = 1,8288019515140650133147431755739e+12673

5000! = 4,2285779266055435222010642002336e+16325
10000! = 2.8462596809*1035,659
25206! = 1.2057034382*10100,000
100000! = 2.8242294080*10456,573
205023! = 2.5038989317*101,000,004
1000000! = 8.2639316883*105,565,708
1,0248383838*1098! = 101.0000000000*10100
1,0000000000*10100! = 109.9565705518*10101
1,7976931349*10308! = 105.5336665775*10310

amazing x) 

here is the crappy calculator source don't get shocked x):

mov esi,12d
mov ecx,esi
Fact0:
dec ecx
imul esi,ecx
mov edx,esi
mov ebx,edx
xor edx,edx
xor esi,esi
mov esi,ebx
cmp ecx,1
jnz Fact0

PS: at the moment it can only calculate to 12!

and btw if you know some tricks to count large numbers tell me please!

RED ARENA

My team mate Xylitol has done a great job when created this website project called RED ARENA which is a contest website so that everybody can share their crackmes and/or keygenmes and also try to solve some other ones ;)

i've coded an easy keygenme which is already in there and has been solved by qpt

rEd ArEnA KeygenMe 1:
PROTECTiON: MD5 + Base64
RATiNG: +3 ( i guess it's easier! ) 

wait for the 2nd ;) i'm coding it right now :)

ViSiT RED ARENA AT: http://bit.ly/feI8F9

now go and solve some challenges :) 

PS: NO SOLUTiONS HERE!

Decrypt This Cipher - Decryption Solution

since no one had tried this i'll just post the solution :)

the cipher is:

110.211.310.211 110.211.110.111.210.111 110.311.410 110.211.110.111.310 110.211.210.111.110.111 110.311.210.111.110

the question is: how much 10 and 11 x)
we have one 10 two 11 three 10 etc...
we'll get this:

101111101010111110111110111010111011111110101010101111101110101010111110101110111011111110101110

this is like the 1st step except that we always add a 1 means: one 1 one 1 one 1 etc...
so all you have to do is to remove them (1x1x1x1x1x1x1x etc...) it's just a matter of lengths :p

011000110110100101110000011010000110010101110010

see how it has become?
yes that's the original encoded binary now all what you have to do is to decode it :) and you'll get the decrypted text which is: cipher
easy isn't :)

qpt's easy keygenme 1 Solution

an easy keygenme with some math instructions no protection or crypto or anything else it's all clean :p

Analyzes:

Decrypt This Cipher

 here is a cipher for you to decrypt :) it's easy just use your brain :D

110.211.310.211 110.211.110.111.210.111 110.311.410 110.211.110.111.310 110.211.210.111.110.111 110.311.210.111.110

Hint: It's a word nothing except a word :]

if you need more hints let me know about it ;)

Edit: i've changed the word and the look too :p so have fun :D
