Hi,

I'm currently evaluating your product for creating self-extracting encrypted zip files.

At the moment, I'm able to generate an encrypted zip, and saw in the release notes of v13 that there was support for self-extracting archives. I already looked at the documentation, but didn't find much about this topic (there were some hints for using sfx* properties, but not much) . Can you please give me a short instruction on how to turn the generated archive into a self extraction archive ?


Regards

Bart

Thank you for contacting us.

Our sample that is located in \EldoS\SecureBlackbox.<edition>\Samples\<language>\ZIPBlackbox\ZipArchiver folder shows how to create SFX archives. Please use it as a reference.

Hi,

I already looked at that sample, but I didn't find anything w.r.t. self extraction archives ?

Maybe the sample is not updated after the release of v13 or am I missing something ?

What SecureBlackbox edition do you use (VCL, .NET, Java etc.)?

Thank you for the clarification. Indeed the ZIP samples don't cover the self-extraction functionality.

This functionality has been copied from OpenPGP, and the samples there show how to create a self-extracting OpenPGP file. Maybe this can help.

We are working on improving samples and documentation all the time (right now we are writing a huge block of how-to articles on all topics), so self-extracting archives will be both documented and added to samples ASAP.

I will discuss with developers if we can improve the samples right now for you.


Sincerely yours
Eugene Mayevski

To add - here's the topic from the how-to that says how to create a self-extracting archive:

Quote

To create a self-extracting archive, set SFXEnabled to True, then specify the desired SFX parameters using StubSource and StubName properties.

Example:
ZipWriter.SFXEnabled = true;
ZipWriter.StubSource = TSBZIPStubSource.ssFile;
ZipWriter.StubName = "C:\\Program Files\\EldoS\\SecureBlackbox\\Extra\\ZIPSFX\\sbconstb.exe";


The stubs can be found in SecureBlackbox\Extra\ZIPSFX directory on your disk.


Sincerely yours
Eugene Mayevski
