title: Setting password in SQLCipher
body: <p>I want to create a new encrypted database with SQLCipher, I didn't really undestand how to set a key due to the following link: <a href="http://sqlcipher.net/sqlcipher-api/#key" rel="noreferrer">http://sqlcipher.net/sqlcipher-api/#key</a> </p>
  
  <p>As the documentation explains, I have to set a key with PRAGMA, but from where do I excecute that command?</p>
