SQLCipher is an open source extension to SQLite that provides transparent 256-bit AES encryption of database files.

SQLCipher is an open source extension to SQLite that provides transparent 256-bit AES encryption of database files. SQLCipher has a small footprint and great performance so it’s ideal for protecting embedded application databases and is well suited for mobile development.

  • Blazing fast performance with as little as 5-15% overhead for encryption
  • 100% of data in the database file is encrypted
  • Uses good security practices (CBC mode, key derivation)
  • Zero-configuration and application level cryptography
  • Broad platform support: works with C/C++, Obj-C, QT, Win32/.NET, Java, Python, Ruby, Linux, iPhone/iOS and Android
  • Algorithms provided by the peer reviewed OpenSSL crypto library.
