I don't see support for decrypting password-protected spreadsheets. Is this feature beyond the scope of this library?

Is there a way to programmatically decrypt spreadsheets? Doesn't need to be JS.

@surjikal I'm sitting on a unmerged patch to support password encryption (FF is triggering "out of memory" errors, which is why I haven't merged it yet). If this is something you'd like to see sooner rather than later, I can prioritize it.

In the interim, it appears that the Java library POI (https://poi.apache.org/encryption.html) supports password protection

Very cool! Right now, I'd only need this for node, so the FF stuff would not affect me. Maybe you could push the change to a separate branch?

Very cool stuff overall. We need the support for reading password-protected spreadsheets for node environment as well. Thanks

@surjikal Any progress on this? Being able to read a password protected xlsx file would be very useful for me. Did the commit above by @clarketm that links to this issue actually impact password/decryption support?

@sgilroy Sorry, I have not looked at the patch above. I posted this issue almost 3 years ago! Thanks for bringing it to my attention though, might be useful someday.

@SheetJSDev Is the patch you referred to back in 2014 https://github.com/SheetJS/js-xlsx/issues/47#issuecomment-35060977 available on a branch or fork somewhere? I'm using js-xlsx in nodejs, so a Firefox memory error would not affect me.
