I am assuming the following:
– You are using AxCrypt 2.
– You have shared the file key with the recipient, by adding the recipient’s email address to the list of users the file is shared with.
– You have sent the encrypted file to the recipient somehow, perhaps via email or by sharing via a cloud storage provider.
The recipient then needs to have AxCrypt 2 installed on his/her computer and has a verified AxCrypt ID account and has set his/her password.
The recipient then double-clicks on the file, signs in to AxCrypt if required, and the file opens.
