I hope to encrypt sqlite file which store my app data.
Is there a simple way to do this?
Welcome any comment.
Thanks

There are a few commercial options which provide add-ons to SQLite for encryption. The most likely candidate is:
The SQLite Encryption Extension which is developed by the original author of SQLite. This is distributed as source and can be compiled for any platform. In this way, you could compile your own embedded version of SQLite instead of using the system one. It provides both RC4 and AES encryption.
There are two other products, but appear to require Windows:
SQLiteCrypt - AES encryption
SQLite-Encrypt - AES encryption
Both seem to have very similar features, but it isn't clear if you get the source to recompile on iOS.

I utilized the realm encryption example to make a Key and encrypt the Realm database. Then I used the Realm().writeCopyToPath(_:encryptionKey:) to make a copy to ship with my app as indicated by the documentation. I believe its my lack of knowledge in encryptions, but how does a shipped app know the encryptionKey when the user downloads the application for the first time as the key was stored in the keyChain. I assume that hardcoding the encryptionKey is a bad idea so I was wondering what the correct approach to doing this was. Thank you for your time.
It's the lack of general technical feasibility, which makes it hard to come up with a solution. When you ship encrypted prepopulated data, you have to include the encryption key as well, which means in effect that the data is not secure anymore because security by obscurity doesn't really work.
If you have some data to prepopulate, which you wouldn't consider to be sensitive, but want to store sensitive user data in your Realm, then I'd recommend loading the plain bundled data from a separate read-only Realm instance and use writeCopyToPath(_:encryptionKey:) at runtime, with a randomly generated key, you can place in the user's keychain.
While if you're afraid that e.g. your level data for your game will be stolen on a jailbroken device, where you can't count on the FairPlay encryption, bundling an encrypted Realm gives you another level of hardening for a possible "attacker". But you should make sure that you obfuscate the encryption key when you integrate it.
Depending on your use-case, you can use one of both ways or combine them both.
Beside that there is a CocoaPods plugin cocoapods-keys, which is a popular way with some great ideas how to manage encryption keys while development.
Hello,
Can anyone tell me how to encrypt the .db or sqlite file in Xcode so as to prevent others person to access the data of .db file ?
I have given the ipa file for testing and the tester is able to access all data in .db file.
So can anyone please suggest any mechanism to prevent users to see the data in .db file ?
Thanks.
The best way as per my research & understanding is to use the OS level encryption, by that way you reduce the chances of getting into runtime DB issues.
I recommend you have a look at this article which explains/talks more about it in detail.
Core Data and Enterprise iPhone Applications – Protecting Your Data
Maybe you can use this project to encrypt your database with Core Data
Or you can use this API with this wrapper to encrypt your .db

Full Database Encryption for SQLite
SQLCipher is an open source extension to SQLite that provides transparent 256-bit AES encryption of database files.
I have an encrypted version of an sqlite database
and also I have the KEY
but honestly I have no idea about using it or how to get the data from the encrypted database?
I guess the solution somewhere in the open function?
if(sqlite3_open([_dbPath UTF8String],&database)==SQLITE_OK);
Can anybody help me??
The core SQLite database implementation does not itself provide encryption support. There does however exist a number of extensions for adding encryption to SQLite. Some of these encrypt the entire database file while some other only encrypt the contents of the tables.
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#. And if you're lucky that extension is also supported on iOS.
i am able to create sqlite database using firefox addon and use database in iPhone. Now I want to give the the password to database and used it in my iPhone application. i tried a lot on google to search the proper way yo create password protected database but still no success.
anybody have idea that how can create the password protected sqlite database and how can we use it in iPhone
Try SQLiteEncrypt.The SQLiteEncrypt is an AES encryption embedded SQLite database engine through which you can encrypt and decrypt your SQLite database file. When set a password key into your database file, content is no longer stored in cleartext, so that we achieve the purpose of data protection.
But it is not free.
Note: But IT is not for iOS (thanks brad to pointed it out).
*Edit***
For iPhone you can use SQLCIPHER which is an open source full database encryption for sqlite.
Unfortunately, there is no free solution for doing that.
There are some commercial applications, which allows sqlite database encryption.
Also, there is virtual filesystem support in SQLite, where you can change calls which reads/writes data to SQLite database, however that will require some coding.
I need to implement data encryption in my app locally, as well as transfer data over the network, after encrypting it.
Can anyone help me by guiding me to good documentation or resources to acheive this? I have looked upon Apple's cryptoClient application but it's too cryptic(contains Bonjour sharing etc. which I don't need).
Use ZipArchive to encrypt the files (check the documentation, there is a way to zip the data with a password) and since you are gonna transfer the data over the network you should make it as small as possible by zipping it.
This is a great tutorial on using ZipArchive:

You can have a look at SQLCipher to encrypt sqlite database, which can store your data locally and to transfer over internet you can simply use HTTPS.
