Re: Decrypt PGP Files

Below is a link to Delphi PGP components. I used an older version of the
library 1.x and current version is 4.12.

http://idw-doc.homepage.t-online.de/PGPcomp.htm


I was using an earlier version, but it was quite simple to get it working.

PGPDecode.FileIn := 'c:\temp\test.zip.pgp';
PGPDecode.FileOut := 'c:\temp\test.zip';
if not GeneratingKeys then
begin
PGPDecode.DoDecodeFile;
Invalidate;

end;

I have one other method that is used to set the passphrase and it works
fine.

Download and install a PGP package for Windows on you PC.
Downlaod and install components into Delphi (I use Delphi 5)
Play with sample programs. I have yet to run my app as a system service,
but that is next on my list of things to do.

Hope this helps.
