Hello,
We don’t support self-decrypting archives in version 2 for the following reasons: https://forum.axcrypt.net/blog/avoid-self-decrypting-files/ .
Nobody needs anything *installed* on their machines if you want to share files or send them to others. They *do* need AxCrypt. Which they can get as a bundled executable + the data (i.e. self-decrypting), or like it works now, they download or get the standalone version of AxCrypt. No installation required. Plus the encrypted file of course.
Version 2 does not share passwords via a server. That’s not how it works. It works using strong public key cryptography. You just enter the email address of the user who should be able to open the file using the “key sharing” feature. Then you send or share the file. No password sharing required.
