Apache uses OpenSSL to implement the transport encryption for HTTP
connections. You can find out more at http://www.openssl.org
This isn't necessarily how you would want to encrypt things on disk, however.
Encrypting a regular file or db file is not really a typical public key
encryption task -- typically this is done by using a block cipher like
Blowfish and a single shared secret. Information is available at:
http://www.counterpane.com/blowfish.html, and there are perl modules on CPAN
as Crypt::Blowfish.
Hope this helps.
