Hi, Thorsten.

First of all:Thanks for your effort, basically it's what many need and have written about it many times

Minor problem: Seems like the module prefix is missing in line 1673.

Bigger problem:
* Even with that prefix added, the ZIP file is being created with the two jpgs in unreadable format.
* 7zip doesn't prompt me to enter the decryption pwd.
* IrfanView complains that it can not interpret any of the two files
(complains about unreadable file header). That's already the case with the files in the example .zip you provided.

The jpg file outside the archive is ok, though.

This is not an error because the datas in the archive are encrypted and therefore cannot be read.

PureBasic does not support password protected archives and this would not be really secure (BruteForce!).
With me the files themselves are encrypted and then packed into a normal archive.
To be able to read them, they must first be unpacked (and decrypted) again.
So you can only read the pictures in your program or put a small unpacker in the archive.

Well, thank you Thorsten.
The missing prefix was surely rather a "glitch" than a "bug".

I obviously somehow misunderstood this part.
"Add encrypted files to the archive or or decrypt files during unpacking"
Never mind, good work though.
Thanks for the quick reply

I wrote a small unpacker, because the normal unpacker can unpack the encrypted files, but not decrypt them.
The source code also demonstrates the practical use of several of my modules.
