ElGamal Tool v1.0

After a long disappearance, I came up with a new tool, but this time it is not a MASM32 tool. 

At first This tool was intended for private use only, but then i had a second thought to publish it, so that others could use it.

This tool can help you generate ElGamal keypairs and much more. It was coded with C# (requires .NET Framework v4.0 or you can use DotNetBox).

Snapshot of the tool:

If you have found a bug, or have any comments or suggestions about the program, post it in this blog or send me an email at xspider15@gmail.com.

Not everything is secure!!

It's been a while since i've posted something :/ well here i am now ;)

While i was searching for some new applications out there, i have found a nice one called Ultimate Password Saver i liked the name and i have downloaded it jk :p anyway i wanted to see how do they do to save our passwords so i went to the folder where it's installed and found a folder called Data, that folder seemed suspicious :) in the end it's the right folder where they save our Logins and Passwords (..\Data\Pwd.zip) but the extension was .zip but when you open it in notepad you'll see that's it's a .mdb (the famous extension of the access database) not to mention that this db is used by Visual Basic coders :) the good thing is that the db was password protected, but does it mean it's safe? not at all ;) I've opened that application in ollydbg and look what i've found :D

you can see that the password "mysoft" is hard-coded and anyone can break into your database without making any effort..

The main idea of all this is to show you that not everything that seems secure from the outside is really secure and that you just have to look for further information and then decide whether it's safe or not ;)

eHash v0.5

Description:
eHash is a freeware hash generator in that supports the most popular hashes for both files and textes.

eHash uses:
    - HashLibrary v1.0 by UFO-Pu55y
    - CryptoHash Library by drizz
    - BigLib v0.01e by roy|fleur

Its main features are:
 - Supports most popular hashes including: CRC Family, MD Family, SHA Family, and much more...
 - The output can be encoded to several bases.
 - Exports generated hashes to: *.txt and/or *.html

If you have found a bug, or have any comments or suggestions about the program, post it in my blog or in our forum.

PS: i'm still looking for a faster way to generate hashes for large files so if you have a solution post it here plz :)

MD5 Hashing Box v0.6

update v0.6 fixed some bugs removed the 0x format (it was useless )

DL: _http://0x58.kilu.de/MD5HBox06.rar

please test it and replay here if you find some bugs

and have fun

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

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!
