Using asymmetric cryptography based on primes (*especially* RSA) for the 
exchange of actual data is a reliable way to break the security of 
communications. They are susceptible to the "known plaintext" class of 
attacks unless random padding is used to mitigate this issue. Anyway, it 
is rather a waste - symmertic ciphers are significantly more efficient.
