Password protected file

[hieubq90]

I have a use case for my business scenario where I need to password protect my generated excel files before I can email them to the client.
It would be great if we can have a password protection feature in the library.
Thank you!

Thanks for your issue. I have added this feature request to the Roadmap. In order to support encryption, we need to implement these encryption standards and many more. It would require a very large number of test cases would be several weeks of work involved. That's an interesting job and I will consider adding support for this feature later. I'll certainly accept that patch if somebody did that an also welcome to contribute to this project.

Would it for now be possbile to expose the xlsxWorkbookProtection struct in the public API? That way I could implement password protection on the application side for now.

Welcome to contribution! I think xlsxWorkbookProtection needn't be an exportable struct. We can add a new function such as SetPassword() to manipulate it internally.

Any progress on this?

This feature is essential.

Has anyone found a way to get it working temporarily until it's officially released?

two years latter....Still not implemented

I just initialize the decryption protection spreadsheet support, and I'll add encryption support later.

This issue is closed. May I ask is there any time plan for encryption support? The document mentioned: "The excelize just support decrypt and not support encrypt currently, the spreadsheet saved by Save and SaveAs will be without password unprotected."

Sorry for my late reply. I have just initialized the workbook encryption support. Please upgrade to the master branch code if you like.

Whether it can be found in readme example encryption usage?

Hi @kernel-1, please update and use the master branch code for the beta, and reference the example. Specify the password in the options of the SaveAs function. Note that this feature is still a work in progress, and will be released in the next version.
