SQLCipher is an SQLite extension that provides transparent 256-bit AES encryption of database files. Pages are encrypted before being written to disk and are decrypted when read back. Due to the small footprint and great performance it's ideal for protecting embedded application databases and is well suited for mobile development. SQLCipher was initially developed by Stephen Lombardo at Zetetic LLC (sjlombardo@zetetic.net) as the encrypted database layer for Strip, an iPhone data vault and password manager (http://getstrip.com). TCL extension (libtclsqlite3.so) can be enabled with: WITH_TCL=yes ./sqlcipher.SlackBuild Note however, it will clobber the stock sqlite library.
