I am currently working with serialized objects, but would like to have them safely stored in a file system without the host being able to see what is inside the objects. The files would be generated and consumed by the same app that would have the key. Is there any encryption/decryption package I could wrap into the serialization/de-serialization process?
I’m having a hard time trying to navigate the packages I could use for this. I tried looking at OpenSSL.jl but the documentation is sparse. I also looked at Nettle.jl as well which has better documentation but seems to be unmaintained (or maybe it’s just mature?). Is there some form of consensus as to which package would be most suitable for this?
I have been using Nettle.jl for many years and have been very satisfied with it, it might well just be mature. The only other alternative that I found was AdvancedEncryptionStandard.jl which is the opposite: its first release (0.1.0) was released a few months ago.
Lightweight encrypted databases can also work in this scenario.
I generally use GitHub - sqlcipher/sqlcipher: SQLCipher is a standalone fork of SQLite that adds 256 bit AES encryption of database files and other security features. to store encrypted data – it’s a popular fork of sqlite that adds encryption. Julia bindings are SQLCipher.jl – exactly the same code and interface as SQLite.jl, but with the sqlcipher library instead of regular sqlite.
