how to set Password when writeFile ?

[parkAlly]

I want to set password when writeFile.
Do you support that feature?

var wb , ws = {}; 
ws['!protect'] = false;
wb.Sheets['test'] = ws;
XLSX.writeFile(wb, 'xlsxFile', {password : 'test1234'});

A quick note on the feature: XLSX / XLSB ("ECMA-376") encryption involves generating a normal file and packaging the whole thing in an encrypted blob within a CFB container (the same type of container used in XLS).

We offer this in the Pro compendium. Since companies have paid for the features already, it would be unfair to them if we turned around and made it available as open source. We have a longer comment in a gist.
