NSS supports encryption. Regarding email attachments, NSS supports CMS (RFC 3852) which is used in encrypted/signed S/MIME emails. Usually, if all text and all attachments of an email are combined into a single grouped message (according to MIME standards), and the result is encrypted. The work to group multiple pieces into a single MIME message is a job done by an application, and after this step, you can use NSS to encrypt it. > Is there an API available that can take > advantage of encrypting file attachments using NSS? I don't think so, in addition to using NSS, your application should use a MIME library to prepare the input message for the encryption operation. > Btw, will the next > release of Thunderbird 17 include the NSS 3.14 library? Thank you. Unlikely, I'm afraid NSS 3.14 got released too late for the Mozilla release process. Here are the versions of NSPR/NSS currently being used by the various Mozilla release branches: https://kuix.de/mozilla/versions/ But given that Mozilla 17 will be an Extended-Support-Release (maintained for enterprise consumers for one year), it would be good if the Mozilla 17 branch eventually picks up NSS 3.14 in one of its scheduled security fix releases (17.0.x). I can't promise it, but it seems likely. In any case, if you decide to build your own local copy of Thunderbird 17.x, it should work just fine to build against the newer NSS library. Regards Kai
