When using Delphi 2007 with Indy 9, which OpenSSL libraries can be downloaded and where are they available?
You need the following two DLLs:
You can download the source code from the OpenSSL.org open source organization , but then you must compile the DLLs yourself. Indy maintains a compiled binaries site for each version of Indy and OpenSSL (see indy.fulgan.com/SSL and indy.fulgan.com/SSL/Archive - thanks to TLama for links).
Older versions of Indy are not compatible with OpenSSL libraries (see Indy and โFailed to load SSL libraryโ using Delphi 2007 / Apache ). TLama added a comment to your question to look at the Embarcadero discussion about it. In this discussion, Remy said: "Try the old 0.9.6 DLL at http://indy.fulgan.com/SSL/Archive/ ." This is probably the version you will need to use.
