I have an RSA signature of 1024 bit where i know the following:
- Public modulus N
- Public exponent (0x03)
- Cypher message
An MD5 hash is calculated from a collection of byte and is used as message (M).
Having an hash that is a perfect cube forge a signature accepted as valid will be easy.
Can someone give advice to find a pratical way to hashing messages changing ending until their hash will be a perfect cube?
