How to encrypt files in the cloud?

Question

Encryption

How to encrypt files in the cloud? Preferably automatically.
Now I do everything by hand. Namely - first I work with the encryption program (transparent encryption, mounted disk). Then I will unmount the disk and synchronize the encrypted files with the cloud.
If you enable both encryption and synchronization, then we get a conflict when working with the file. They changed the file - the program encrypts it in the folder, and the other one is already trying to synchronize it with the cloud. The file is corrupted and the data is lost.

Answer 1

In this case, utilities like TrueCrypt \ VeraCrypt become useless. It is necessary to encrypt by files BEFORE the cloud so that google sync \ yandex disk uploads already encrypted content to the cloud.
