The best size for an RSA modulus depends on one's security needs. The larger the modulus, the greater the security, but also the slower the RSA operations. One should choose a modulus length upon consideration, first, of one's security needs, such as the value of the protected data and how long it needs to be protected, and, second, of how powerful one's potential enemies are.

I have an encrypted message using a key which we are not aware of and here we need to decrypt that same message to its original form. Can that be possible without knowing the shared key. If so please let me know the solution
