We are using PouchDB the save our data locally. We want to make sure that data is saved securely.
If we are encrypting the data itself via a plugin it is not possible to query our DB because all the data is not readable anymore...
Is there a way to make sure data is saved securely without encrypting the data itself? Is it possible to encrypt the database as a whole?

How can I encrypt data in Redshift using KMS so that it is not visible to anyone who queries the table or anyone at all in the account at all?
We plan to decrypt the data manually later.
Can you explain the easiest way since I'm doing some POC.
I have an SQLite3 database that I need to secure.
I'm confused between using sqlcipher to encrypt the whole database that I use in my Electron app or simply encrypt the data using crypto dependency.
Any clarification or explanation would be welcome.
There are two different types of encryption: "encryption at rest" and "row level encryption".
What if someone gets access to your SQLite file? They have all your data. "Encryption at rest" protects you against this by encrypting the SQLite file itself. If someone steals your SQLite file it will be useless to them. sqlcipher provides encryption at rest. This is a good idea in general.
What if someone hacks into your application and injects SQL commands? What if they select all your customer data? It doesn't matter if the file is encrypted, the SQL connection will decrypt it. To protect against this you can add a layer of "row level encryption". This is where your application encrypts the data it writes and decrypts the data it reads. The data being stored is encrypted. This is more complicated and has more performance impacts. Since the data is inserted encrypted, it is more difficult to search and index. Use it only for very valuable data that you're not likely to have to search. You're better off securing your application against SQL injection in general.
I need to store OAuth token, and various quite sensible user information data into my firestore. I've learned that Firestore is safe and that they already encrypt data, should I do it still ?
If I do it, I'll use a key stored in .env to encrypt / decrypt data via a aes-256-cbc cypher but I think it might be overkill...
PS. I use Next.js API Routes
Encrypting the data is entirely optional and doable, but the practicality of doing so far exceeds the actual usefulness of any encryption implementation.
The data is already transferred securely via HTTPS and decoded on the client. If you were to encrypt the data, any information to decode the data would also be available from within your app, making the encryption redundant.
The only reasonable risk is if the clients' device is compromised, hackers can access the decrypted data directly but that is not feasible to prevent.
Can we save any data from the javascript. In my site I want to use RSA encryption but I want save privatekey into users browsers not to the server's databases.
The LocalStorage object can be used to store and load data on the client end.
Note though, the data it stores is temporary. If the user wipes their temporary files, the data will be lost. There is no way around this. If you need permanent storage, you'll need to send the data to the server and store it there.
Also note, the client can view and edit LocalStorage.
I'm using a monetdb database to store massive amounts of sensor data such as data from accelerometers and gyroscopes. Now I need to restrict the access to the data. To restrict the access through the database interface (by use of SQL) I created a user account with password. The problem now is that I also want to prevent the access on the level of the file system (e.g. copy the data and load it to another monetdb installation).
Is there any way to tell monetDB to encrypt the files that are written to the filesystem?
This is not supported. Perhaps consider an encrypted file system?
