AxCrypt 2.x can decrypt the AxCrypt 1.x encrypted files with the password used. But AxCrypt 1.x can’t decrypt/open the AxCrypt 2.x encrypted files.
AxCrypt 1.x is a legacy version. That means it is outdated and there is no longer any support for it, whereas AxCrypt 2.x is the version that we are continuously working on to keep improving it. We recommend all users, old and new, to always use the most recently released version of AxCrypt.
Please ask your friend to use the latest version of the AxCrypt 2.x application. For more information, please contact our support via email@example.com .
