Can I encrypt a purely in-memory database using SQLCipher?

Question

The official SQLite Encryption Extension does not support encrypting in-memory databases per their documentation: https://www.sqlite.org/see/doc/trunk/www/readme.wiki

Limitations

1. TEMP tables are not encrypted.
2. In-memory (":memory:") databases are not encrypted.
3. Bytes 16 through 23 of the database file contain header information which is not encrypted.

Does SQLCipher have these same limitations?
