พูดถึง Android SQlite password encryption ยังไม่ค่อย Get เท่าไหร่
หลายๆ คอมเมนท์บอกว่า "ทำยาก"
อย่างมีคนหนึ่งพูดว่า
As far as I know: no, you can't do it in a simply way.
Posible choices:
-You could simply encrypt the data you want to be secure when inserting it and decrypting the values when you want to play with them. In my opinion this is the best choice.
-You could encrypt the db file in your app's folder. And decrypt it every time you want to access it (not very recommended).
Also note that your DB file is stored in your app's private directory, so in most terminals (except for rooted ones) neither the user nor other apps will have r/w access.
EDIT: For the first choice, I recommend you to take a look to mah's answer if you don't want to implement your own encryption methods =)
