Hello,
I'm developing a WPF application in C# and using SQLite as the database. Currently, my database file is unencrypted and can easily be viewed or modified using any SQLite management tool. This is not acceptable for me in terms of security.
My first thought was to encrypt the database. However, during my research, I found that many libraries offering this functionality are paid.
Is there a way to achieve this for free? How can I prevent unauthorized access to the data?
As an alternative, I considered encrypting all data before saving and decrypting it when reading, but I decided against it for now due to the potential increase in code complexity and maintenance effort.
I would really appreciate it if you could guide me on how to handle this.
Thank you.
Did you test SQLCipher Community Edition ?

as suggested there are a couple forks of sqlite with encryption. also you can encrypt data before saving. The main issue is how to manage the encryption key. if the user switches to a new computer and restores from backup do they lose all their data?
Hello
I may be a little late in terms of encrypting and recording the data and displaying it by decrypting it. Because I have completed 70% of the project.
If I encrypt and record, I can store the encryption key with the Windows identity manager. But right now, protecting the database by encrypting it seems like the best option. However, since the libraries I found were paid libraries, I could not use them.
Hello,
I’m developing a project using WPF and SQLite as the database engine. To ensure data security, I want to encrypt the database. During my research, I came across some conflicting information, so I’d like to hear from others who have faced similar requirements and found a working solution.
Currently, I’m using the Microsoft.Data.Sqlite package in my project. It is developed by Microsoft, lightweight, and has a modern structure. However, it does not offer built-in support for encryption.
As an alternative, I found the System.Data.SQLite package, which is said to support encryption. However, I’ve seen comments that it is based on an older architecture, has a larger file size, and may have performance drawbacks. For these reasons, I’m hesitant to switch to it.
Later, I came across a package called SQLitePCLRaw.bundle_e_sqlcipher. This package provides encryption support and is said to work alongside the Microsoft.Data.Sqlite package I’m currently using. However, it's explicitly noted that this combination is not officially supported. This makes me a bit concerned about potential issues with updates or cross-platform compatibility in the future.
At this point, I’d like to ask for your input:
What do you think about implementing the setup I described above? What would be the best path to take in this case?
Thanks in advance.
