/* SQLCipher usage note:
If the current database is plaintext SQLCipher will NOT encrypt it.
If the current database is encrypted and pNew==0 or nNew==0, SQLCipher
will NOT decrypt it.
This routine will ONLY work on an already encrypted database in order
to change the key.
Conversion from plaintext-to-encrypted or encrypted-to-plaintext should
use an ATTACHed database and the sqlcipher_export() convenience function
as per the SQLCipher Documentation.
