Which is fine.  In C and C++, C style arrays decay into a pointer to the first element.  In Pascal, passing an array by reference will pass the same memory address.

It is not supposed to be initialized.  That variable is used with an output-only parameter of EVP_DigestFinal_ex().  OpenSSL will assign a value to the variable.

Known issue, it was reported to me a month ago:

I've opened a ticket for it in Indy's issue tracker:

I'd like to avoid using the DynLibs unit in any of Indy's interface sections, if I can avoid it.  But point taken, apparently I can't use HMODULE.  I'll likely just end up using THandle instead, or at least TLibHandle.

Maybe THandle is the best option. I used it in many cross platform projects along years with no problem.
