I got no answers about my post in German, so I retry it in Eglish, sorry for the mistakes.
Drop box withBox ryptor is running well on my computer. But I want to share a box Cryptor file with a fried of mine far away. He shall open this file on his own computer. With only drop box no problem, but how can I reach this while combined with box cryptor?
Why not phone him and tell him the password you have used on a folder you want him to access.
Share the dropbox folder normally, as you would without Boxcryptor.
He then uses Boxcryptor to to acces it.
like Ian points out sharing the whole BoxCryptor Folder is the only possibility to share an encrypted file at the moment.
We're working on a real sharing feature but I can't give you any more info at the moment.
