Sorry about that, I guess I didn't provide enough detail.

Here is what I am doing: The encrypted data file will be read by this program only, so I don't think I have a need for public key encryption. It is actually going to end up being a CGI program that allows the client to log in, enter some data, and retrieve this data later, all of which will be stored in this encypted data file.

Hope that helps a little more - thanks!

Update: I have found that using Crypt::Blowfish for the encryption along with Crypt::CBC to allow me to encrypt large files without having to manually break them into 8-byte chunks work wonderfully. And it is fast, too!
