comment decrypt a saml 2.0 response having aes 128 and rsa
The modulus and exponent together make up an RSA public key. You're right, you presumably don't need them for decryption, but at least you can check that they match the private key you have.

comment How do you break encryption on a message?
Your questions seems really broad, perhaps too broad to be answered well on a Q&A site like this. What you really need is an introductory book on cryptography and cryptanalysis. Here's a few choices to get you started.
