RSA doesn't scale, so if the message is large then RSA becomes unwieldy. So most encryption methods that make use of RSA actually encrypt the data with a symmetric algorithm, and then just encrypt the key for the symmetric data using the RSA key.

But there is still way way way too many ways to implement crypto wrong, which can completely compromise the security of it.
