Problem:
When using the Indy SSL components, an error 'Could Not Load SSL Library' is raised.
Answer:
This error is raised because you must have OpenSSL installed on your machine in order to use the IndySSL components. At runtime, Indy attempts to load libeay32.dll and ssleay32.dll. Due to restrictions on exporting SSL technology, these .dll's are not distributed along with Indy. Please review Indy's SSL site for information on where you can obtain the OpenSSL .dll's.
