Hello Antonis,
Free subscription user open/edit the encrypted file, so User B, cannot send it back to user A. User B account required a Premium account.
You can send the encrypted file securely with others using AxCrypt key sharing.
You can use the AxCrypt key sharing feature to encrypt your file(s), then key shares the file with other recipients, If they want to open the received encrypted file then we have to share the file password with them or the files should be key shared with receivers’ email addresses.
I will explain about the key sharing features:
There is no need to share passwords in order to send or share files securely with others.
AxCrypt has a key sharing feature letting you add recipients by email address, who when they receive the file can open it with their own AxCrypt password.
Key sharing embeds the shared key into the file. The file must thus first be key shared with the recipient, then sent or file shared. Please note that AxCrypt does not share or send the actual file. To see a quick instructional video explaining how to use key sharing, please view https://www.youtube.com/watch?v=9z3KOZD-Yks .
If you are asking any other quires, you can feel free to contact our support via support@axcrypt.net .
