The "officially blessed" (my wording) encryption for SQLite is SEE (proprietary):

There are third party encryption approaches for SQLite. One of the most popular is SQLCipher:

Those two don't have compatible file formats. eg no interoperability

Not sure if any others do, but yeah it would be handy if there are.
