IndySecOpenSSL

This repo provides the IndySecOpenSSL package for both Delphi and Lazarus/fpc. This package provides a new (optional) OpenSSL package separate from Indy's "protocols" package and adds support for OpenSSL 3.0 and later. It may be used as an add-on the Indy 10.6 or the forthcoming Indy 10.7 releases. The IndySecOpenSSL package's purpose is to provide Indy users with an upgrade path to the use of current OpenSSL (3.x) libraries with the minimum of change. This includes users that use the existing version of Indy bundled with Delphi and the version provided with the Lazarus Online Package Manager. For more information on the installation and use of the package please read the comprehensive User Guide provided in the docs subdirectory. New users should pay particular attention to the installation instructions and guidance on installation of the OpenSSL shared libraries (DLLs) included in the User Guide.
