How to encrypt data in BlackBlaze cloud storage?

Question

Data storage

If I understand correctly, stored data is not encrypted in Blackblaze B2. Therefore, keeping it open is not an option.
So far I see two options:
1. Cyberduck + Cryptomator. But how reliable is Cryptomator in terms of operation? What if the files get broken, or after 5 years Cryptomator will stop updating/working and you will have to download hundreds of GB and encrypt it with something else?
2. Archive in zip with a password?
The option with Veracrypt is not suitable, you can’t look inside the container, you can’t see the list of files.
Share your experience?

Answer 1

Use any client-side encryption. As long as you have access to the encryption algorithm and keys, software is secondary. BackBlaze is cheap, in particular, because it is never safe, so solutions from AWS - s3 and analogues from Azure / GCP are much better. I advise you to look at them.
