AxCrypt application will not send any files to the users. We have to send the file via email, drive and etc. If the receiver wants to decrypt/open the shared encrypted file(s), then AxCrypt app is required.
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 .
Sharing a secured file is made directly from the AxCrypt software by choosing the secured file, click the share button and simply select the team member you want to share it to. The recipient just needs a free AxCrypt ID and will be automatically invited via email if necessary.
If receiver who does not have registered AxCrypt ID, (s)he will receive an invitation email with instructions on how to view and edit the file. After that receiver can open the AxCrypt encrypted file in AxCrypt app with own password.(if key sharing applied.)
If the above does not help,please provide more information about the issue and write a mail to firstname.lastname@example.org .
