Feature Request: Convert HWP files (Hancom Office)

[CR0CKER]

It would be hugely helpful if Dangezone was capable of converting HWP files produced by Hancom Office, a terrible office suite that's extremely widely used in South Korea and frequently used for targeted malware attacks against journalists, researchers, defectors, and politicians in South Korea.

Thanks a lot for bringing this to our attention. It definitely looks like something Dangerzone should support.

Looking into HWP, I see that there are several open source projects that are trying to convert HWP files to ODT:

• https://github.com/mete0r/pyhwp
• https://github.com/k2webtech/hwp2odt

Have you tried any of them, or know if something else is more reliable? If we can rely on such a tool, we can use it as a pre-conversion step for HWP files, to grab an ODT document, and then let Dangerzone continue the conversion process as usual.

Thanks for flagging these -- I'll have a look. So far I've only tried the HWP import in LibreOffice but compatibility was very poor, mostly because the HWP format apparently changed significantly in recent years and Hancom -- surprise -- has no interest in properly documenting the format.

[CR0CKER]

Just tried the LibreOffice extension and it seems to work well! Awesome. This is already useful as a quick fix, though HWP support for Dangerzone would be even better.

Duly noted. Most probably this won't be part of the upcoming 0.4.0 release, but it would be nice providing support for 0.5.0 onwards. I'll keep this issue open to track this request.

One more thing I'd like to ask is what else would help Dangerzone users in South Korea? Are translations, alternative installation sources or stuff like that important to users in South Korea? Are other things more important?

[CR0CKER]

While not important to me, a Korean interface would certainly be useful. I'll follow up with further suggestions once I have more experience using this.

I have moved the conversation on the "invalid JSON" bug to this new issue to keep the discussion organized. (how I miss discourse's "split thread" feature to preserve the original authors instead of quoting...)

[apyrgio]

Good call. I didn't know GitHub had this option for comments. Let's keep this issue for the HWP support then.

Here's the open source version of the LibreOffice HWP to ODT Converter. It also supports the HWPX format.

HWP formats are widely used by Korean people, including journalists. Therefore, there are many attacks using HWP format vulnerabilities. This would be a helpful addition to Dangerzone for many people.

I am Korean language speaker, and I'm so much willing to help you add this feature.
