Answer #1

Evilize: create pairs of executable files with the same MD5 hash

Wang and Yu's technique works for an arbitrary initialization vector that we have created using evilize hello-erase -i using that vector it will create two same combination of md5 with random brute force.

A given input IV which given in the parameter 0xe6822ac5 0xd49b1ebb 0x7217a303 0x1a56a4db multiple of 64 bytes. It is then divided into individual 64-byte blocks M0, M1, ..., Mn-1.

The MD5 hash is computed by computing a sequence of 16-byte states s0, ..., sn, according to the rule: si+1 = f(si, Mi), where f is a certain fixed (and complicated) function.

Here, the initial state s0 is fixed, and is called the initialization vector. The final state sn is the computed MD5 hash.

This is very time consuming task that is the drawback of this algorithm.

Rather process is still going on i will post remainaining result once completed as i have 2 hours to solve this.
