FP/Delphi compatible Encryption and Zip Libraries?


Hi all,

Can anyone recommend an encryption and zip library/unit that works with 
both FP and delphi?

The zlib stuff should work well between them I would imagine.

I need to encrypt and compress plain xml packets between two endpoints.

Thanks!

One option is DCPCrupt: http://wiki.lazarus.freepascal.org/DCPcrypt

I never used it though.

yea, that's what I allready did. works.

That's where I am right now. Sholdn't be that hard, because most stuff 
is allready in place: it builds packages, even builds the needed 
packages. That means all the package dependency stuff etc. is allready 
in there, only missing part is creation of the staticpackages.inc and 
idemake.cfg which also "must be somewhere" because lazarus does it.

Tried to figure out, what happens when the "install" button of 
PackageEditor is clicked.. but hey, that's not so easy to follow ;-)

TPkgManager.DoInstallPackage might be the thing I have to duplicate in

We use zlib for compression under both Delphi and Lazarus.  No problems at all.

And we use DCPCrypt for compression under both (same product as the
zlib one) Delphi and Lazarus.  Again, no problems.

They are safe. 
Maybe with the exception: Replacing text, moves source marks.

They don't exist yet.
What events do you need exactly?
'BeforeCompile' is too unspecific, because there are dozens actions
between pressing F9 and the real execution of the compiler (e.g. state
checks, auto saves, file checks, auto updates of resource files,
dependency checks, saves, builds, running before compilation tools).

Let's say I need to include one line with "This new line" and remove 
three lines. I can use Position or Line+Column values.

The line need to be included between lines 5 and 6, or after the 
position 120.

The lines I need to remove are 12, 13 and 14 (now 13, 14 and 15 because 
of the new line). If using the Position approach, characters between 
position 250 and 300, including the last breakline (now between 264 and 
314 because of the new line + #10).
