Hi,
I’ve recently released an updated version of the Delphi Encryption Compendium (DEC) compatible with Delphi versions up to 2009. A code example of using it with Unicode strings is included in the library.
This libary was updated and released with permisson of the original author Hagen Reddman who developed the versions DEC 3 and DEC 5.1.
The Delphi Encryption Compendium supports several hashes, ciphers and text encodings and is imho one of the best libraries for strong cryptography in Delphi. And the best: It is free of charge!
It is available at Torry: http://www.torry.net
Thanks to Michael Puff (a.k.a. Luckie) for hosting the library on his server!
Due to the request here are the hashes for the file DEC_v5.2.zip linked at Torry / Michael’s Server:

Hi,
probably you already encountered the problem that your Delphi IDE crashes instantly when using the TPngImageList Thany made available years ago. This happens if you use the TPngImageList Designtime Package under systems with activated Data Execution Prevention (DEP).
Despite the fact that this problem existed for some years now Christian of the JEDI Windows API Team was the first to write about it in his blog recently.
Mitja P. added a comment which provides the source and a solution for the bug:
There is a function PatchPtr used in PngComponents unit PngImageList that needs a change of VirtualProtect to PAGE_EXECUTE_READWRITE instead of only PAGE_READWRITE if I remember correctly. I am also not sure if I reported this to the author at the time I was playing around with this components or not.
I’ve verified that this fix solves the issue for Delphi 2006 up to Delphi 2009. Thank you Mitja!
Additionally there is an updated version of the TPngImageList (created by Uwe Raabe) available at the CodeGear Repository:
PngComponents for Delphi 2009
As Delphi 2009 only integrates the PNG support into native ImageLists this updated component allows for using your already existing PngImageLists from projects prior to Delphi 2009 without any change to the images!
Please be aware that this version needs the mentioned fix as well, so update the source before installing the package.

I just discovered the official sneak peak videos of D2009 David I pointed to in his blog:

Today I’ve seen that Marco Cantù has posted some videos at youtube showing the unicode possiblities in Embarcadero’s Delphi 2009.
You can find all of his Delphi videos at his YouTube channel.

As Nick Hodges has posted yesterday the Delphi & C++ Builder 2009 ISO files are now online.
See his blog post.
