The general approach is to encrypt data using a symmetric cipher (e.g., AES-256) with a randomly-generated key, and then encrypt that symmetric key with the RSA (public) key.
And for the symmetric encryption you'll also have to make a decision about what mode to use (ECB, CBC, CTR, etc). Whatever you do, don't use ECB :) Phillip On Thu, Jul 8, 2010 at 7:40 PM, Chuck Pareto <chuckda...@gmail.com> wrote: > Is there an algorithm that I can use, similar to RSA with public/private > key, that will allow me to encrypt really long strings (like an email/text > file)?
