How to operate a password protected presentation?


Dear all. I urgently need a solution how to open a "Password-to modify" protected presentation using ASPOSE.Slides. Is it possible?

If no. Do you have an ideas to implement this fiature in next release of .Slides?

Have a nice day!



Dear Vlad,

It’s not possible and we can’t find any information about
presentations crypting in MS PowerPoint yet.



Thank you for your prompt responce.

Could you give me any advice on how to malke a read-only version of power point presentation, that is generated by .Slides at run-time. That is my actual problem!User should not have a way to modify content after downloading,




Read-only ppt files are crypted so it’s not supported.
