I am looking for a service that will allow me to securely upload a file and then obtain a web link to that file which I can then pass on to a recipient to download the file. But I want to be able to specify a password that the recipient will need to enter to download the file. I have a dropbox account but you don't seem to able to specify passwords for share links. box.net provides what I want but not in the free plan. I am willing to pay for the feature, but not $15/month required to use box.net. I would prefer a pay-per-usage service or a plan significantly less than $15/month. yousendit.com has exactly what I want and has a pay-per-use option but whilst trying out their service I am experiencing significant performance issues with their site (site navigation is slow and and uploads often fail). Can anyone recommend other options? Thanks P.S. I don't want to simply encrypt the document and upload it to dropbox. For ease of use (for the recipients), I want the download to be password protected, not the file itself.
