Hi @Fischiii - The two are just not designed to be compatible. It’s conceptually similar to how you couldn’t open a macOS FileVault file system using Microsoft BitLocker. Even though they are both encrypted filesystems, and can both use the same AES-XTS encryption algorithm, the implementation details of the key management, metadata storage, layout, etc. are all different. As a result, while they are comparable technologies, they are not compatible implementations.
SQLCipher uses it’s own specific key derivation operations, database page structures for reserved data and HMACs, etc, as described in our design documentation.
We have never seen or worked with SEE, so I don’t have any direct knowledge of how it works. As a result, I can’t comment on any technical specifics about SEE.
