Encrypt stored data on Backblaze 2 backup

Backblaze 2 backup does not encrypt data which is stored.
What do you suggest is obtained or done in order to encrypt that data?
The data source will either be from a desktop, or it may be from a QNAP or Synology NAS.
Your specific suggestions and instructions are appreciated.

Invisible encryption
When you use Backblaze, data encryption is built in.  Files scheduled for backup are encrypted on your machine.  These encrypted files are then transferred over a secure SSL (https) connection to a Backblaze datacenter where they are stored encrypted on disk.  We use a combination of proven industry standard public/private and symmetric encryption methods to accomplish this task.  To a Backblaze customer all of this is invisible and automatic.  For example, when you create your Backblaze account, we automatically generate your private key that is used to uniquely protect your data throughout our system

That however Backblaze 2 is not encrypted.
If you had read  Iamthecreator OM link you would know that the file is encrypted before transport, transported over TLS, and stored on the servers encrypted. When you create the account your private key is generated.  Your private key is encrypted via your password
Perhaps this link would explain it better https://www.backblaze.com/blog/how-to-make-strong-encryption-easy-to-use/
Hi everyone.
Please do not assume I don't read emails here, please have more respect for those that are asking questions.

I contact Backblaze regarding the B2 service and this was the response I received.

"Thank you for writing in. That is correct. It is not encrypted. If you are worried about encryption, you can encrypt them before uploading the files to B2. Several integrations can do that as well, like CloudSync for Synology NAS and Cloudberry for nearly anything else. You will have to download files through the integration to be able to correctly decrypt them in the future.

Also, for your buckets, you can enable them to be private. Please make sure not to share the link. We do strongly recommend using 2-factor verification and minimizing giving out access to the bucket to help keep the data secure.

We do consider the security of our customer's data a high priority. So we do work hard to ensure our system is not hackable, and customer's data is not accessible.
