I think you can find more info here: http://stackoverflow.com/questions/166340/write-a-password-protected-zip-file-in-java – maqjav Jun 25 '13 at 05:40

Hi coffee, and welcome to stackoverflow (a bit late, but better late then never :) ). You can post your solution as an answer to your own question. It seems separate from the link that maqjav posted, so it's fine to stand on its own, especially if the zip was already in memory... – Maarten Bodewes Jun 26 '13 at 22:45
