The core SQLite database implementation does not itself provide encryption support. 核心SQLite数据库实现本身并不提供加密支持。 There does however exist a number of extensions for adding encryption to SQLite. 但是，确实存在许多用于向SQLite添加加密的扩展。 Some of these encrypt the entire database file while some other only encrypt the contents of the tables. 其中一些加密整个数据库文件，而另一些仅加密表的内容。
These extensions are for the most part not compatible, so you will most likely have to use the same extension on the iPhone as the one used on C#. 这些扩展在大多数情况下不兼容，因此您很可能必须在iPhone上使用与C＃上使用的扩展相同的扩展。 And if you're lucky that extension is also supported on iOS. 而且，如果您很幸运，iOS上也支持该扩展。
