I have an RSA signature of 1024 bit where i know the following:

- Public modulus N
- Public exponent (0x03)
- A lot of cypher message

**Summary:**

An MD5 hash is calculated from a collection of byte and is used as message (M).
Our teacher give us more than one signature in order to recover the private exponente ***d***.

**Question:**

Can someone give advice to find a pratical way to obtain one of several working private exponent **d** searching transpositions of these signature?
