So, then a few more questions:

1. If my app is compiled in Delphi 7 32-bit, but have end-users that have
both 32-bit and 64-bit Windows, would I use the OpenSSL Win32 binaries?
Would they work on both platforms?
2. For the end user, if they chose Implicit (TLS Connection) or Explicit
(STARTTLS) to send, I would not want them to have to fill in (or know about)
the various SSLContext parameters (Verify Peer, CA File, CA Path, Cert File,
Key File, Pass Phrase).  What should I use for the default values for these?
3. For my app distribution, would I simply include libeay32.dll and
ssleay32.dll in the application directory?
