OpenSSL in Delphi
Koger
I want to use SSL in my application, indy seems to support openssl but the
two dll's they require are rather big and not the newest version at all it
seems.
Also I would like all the functions from the opensll library to be available
in my Delphi app. Is that possible at all?

You can check SecureBlackbox (http://www.secureblackbox.com/). It is the
native delphi solution for SSL/TLS and it can be plugged easily to Indy.
You can compare OpenSSL with SecureBlackbox here:

Yes, it is possible but it is a lot of work to translate OpenSSL header
files to Delphi. I've done the job for the small subset needed for ICS in a
way I think it is compatible with recent and future versions. See

You should be able to recompile them, Im pretty sure the sources are for
download from Gregor's site too.

It is not clear that SecureBlackbox doesn't use any DLL and is pure Delphi
code. Is the source code available with enough details so that the user can
rebuild everything as it is possible to do with Indy, ICS and OpenSSL
implementations ? As I understand, SecureBlackbox has SSL code implemented
with Delphi but underlaying crypto functions are something else. Is it true
?

This is clearly stated on at least two web pages on SecureBlackbox site.
http://www.secureblackbox.com/delphi-ssl.html:
SecureBlackbox does <b>not</b> use CryptoAPI, OpenSSL or other
third-party encryption library.
http://www.secureblackbox.com/index.html:
SecureBlackbox^(TM) can be used on Windows and Linux operating systems with
all major development tools: Visual C++, Visual Basic (ActiveX or DLL),
Delphi and Kylix (<b>native delphi</b> code).

As ordering page states, registered license includes complete Delphi
code. It is not possible to rebuild the ActiveX from it though, but
ActiveX wrapper is not part of the Delphi edition anyway. So, yes,
complete Delphi code.

See above.

Check out StrSecII at http://www.streamsec.com/prod_strsec2.asp. It is
the original clean-room implementation of SSL and TLS for Delphi. 100%
Delphi code, and loads of security stuff besides SSL/TLS, such as
S/MIME, regular encryption, multi precision arithmetics etc.

anything less than StrSecII:

You can use the latest versions, they should work fine.
If you want a Delphi only solution, check out StrSecII, I haven't worked
with it but I am under the impression that the author is a professional
who not only programs well but also knows the math behind it inside out.

This reminds me of an old soviet tradition: "I haven't read the book,
but I think that the author should be imprisoned and executed".
Maybe it makes sense to try first?

Absolutely. Our evaluation licenses come with full source and start-up
support. Just drop me an e-mail with a description of the project you
might use StrSecII with, and I will mail you your credentials.

This is because Indy not using OpenSSL. It using 'modified OpenSSL'!
For example, Synapse using standart OpenSSL, and you can use latest
OpenSSL vesion directly. ;-)
