And I will provide more keys for the same username.

I'll have a look at this when I get free minute ;)

Agree with you about that RSA itself can't have collisions ;) It can only be a result of collision in hash.
Otherwise you won't be able to read messages encrypted with RSA - because they could have few meanings :D

What about MD5 - actually now MD5 is definitely not safe (because of this MD5(x)=MD5(y) => MD5(x+z)=MD5(y+z) ). You can check out this article:

Microsoft has even decided to ban MD5:

You can also use 'packet factoring', i.e. you can create ppsiqs.in (or whatsoever).
In this file you put all your numbers that you would like to factor in decimal notation (base-10) like this:

Code:

224723992774119006825578513302384489873

156501211667442645087401128910164446481

119399008393514320049994534947283967297

211087890988599145775593649671167343561

222924203035635853575650313518923532737

Then you type

Code:

ppsiqs.exe < ppsiqs.in

and then you will have results in SIQS.LOG

I suppose you are trying to enter a number written in hexadecimal notation (base-16). And you have to enter a number in decimal notation (base-10).
For example let's factor number

Code:

E7C8A74C73FD2FBAC4F42216DFA687C1

in decimal notation it's

Code:

308093519617663552837864268966148868033

Code:

Input number ( input 0 to exit )

E7C8A74C73FD2FBAC4F42216DFA687C1



unkown function E7C8A74C73FD2FBAC4F42216DFA687C1

Code:

Input number ( input 0 to exit )
