Alternative for NACl module format(.nmf ) in firefox extension
I am developing a password manager add-on for Firefox, where i need to encrypt my passwords while sending to native application. My add-on takes username and password for a host and sends it to native application using native messaging and native application saves it in database. I don't want to send those passwords in plain text while sending from add-on to native application. I have chrome extension which also sends passwords to same native application, chrome uses NACL module format(.nmf file) to do such encryption.
I wanted to know is there any alternative for NACL in firefox.
