digital signature

Hi.

There is digital signature function in the installer project.

Is it for making digital signature or importing digital signature that I made??

Thank you!

Hello,

A digital signature is used to help authenticate the identity of the creator of digital information. Digital signatures are based on digital certificates. Digital certificates are verifiers of identity issued by a trusted third party, which is known as a certification authority (CA). Digital signatures help establish the following authentication measures:

• Authenticity
• Integrity
• Non-repudiation

The Digital Signature feature from Advanced Installer allows you digitally sign your installation package. By digitally signing your installers and products in Advanced Installer, you will increase your user's confidence in you and your company, giving them peace of mind about your software.

Please take a look on the Digital Signature article which may be useful to you.

If you have other questions, please let us know.

Best regards,
Dan

Hi

When I add a certification in version1 and I don't add a certification, updater stops

And I can check the message..

update.png (50.03 KiB) Viewed 4762 times

But!!

I make two different certificates and test updates.

I thought that it can't update because each file has different certificates.

But It can update.......

What is the problem?? TT

Hello,

I'm not sure why you are encountering this behavior. Can you please make sure that the "Compute MD5 signature from file" option is enabled in your updates configuration project and see if the behavior still persist?

Best regards,

I made two files, version1 and version2(version2 is )
2. version1 certification and version2 certification is different.
3. I think the update from version1 to version2 should failed because each certification is different. But, the update works smoothly.(the update didn't fail)

So, my question is
1st) the reason why the update didn't fail.(Why does it work well?)
2nd) To proceed like number3 above (to check fail of update), what should I do?

Hello,

3. I think the update from version1 to version2 should failed because each certification is different

The update process when you are using different certificates may fail only if you are implementing the installation of the updates without elevation mechanism, otherwise it should work without any problems.

If this is not your case, please make sure that your are picking the right file when you are creating the updates file.
