comment How difficult is it to find the “pre-image” of a block cipher?
Or better yet, what about the scenario where $M_1$ and $M_2$ are fixed.

@Thomas I guess I'm asking is there a way to do this without enumerating the entire key space...

comment How can I use asymmetric encryption, such as RSA, to encrypt an arbitrary length of plaintext?
While I do agree that the proposed situation is non-standard, simply saying to use AES I believe is incorrect, since it assumes you can securely distribute keys. Also, what do you mean it exposes weaknesses in the ciphers themselves?

comment Is it possible to use the RSA algorithm, or a variant, for software licensing?
Just a thought, why not pay for or license a license manager? You want to focus on your application, not making sure the license manager is secure and functioning.
