Projects / SQLCipher


SQLCipher provides fully transparent encryption of SQLite databases. SQLCipher is a specialized build of the SQLite database that performs transparent and on-the-fly encryption. Using SQLCipher, an application uses the standard SQLite API to manipulate tables using SQL. Behind the scenes, the library silently manages security, making sure that data pages are encrypted and decrypted as they are written to and read from storage. SQLCipher relies on the peer-reviewed OpenSSL library for several encryption requirements, including the AES-256 algorithm, pseudo random number generation, and PBKDF2 key derivation.

Recent releases

  •  04 Oct 2010 20:19

    Release Notes: This fixes a bug that could cause SQLCipher to report an error opening a valid database when a specific section of the encrypted header contained certain values. It is strongly recommended that all users upgrade to the latest version. The new SQLCipher version should be a drop-in replacement for previous releases.

    •  28 Aug 2010 14:41

      Release Notes: This version is based on the latest release of SQLite, 3.7.2, and thus contains many improvements and bug fixes, including experimental support for the new Write Ahead Log journal mode (WAL).

        •  24 Dec 2009 03:16

          Release Notes: This version fixes a bug that would prevent the attachment of an encrypted database to a pre-existing unencrypted database for the purpose of copying or joining data between the two.

          •  21 Dec 2009 14:29

            Release Notes: This version is based on the latest release of SQLite (3.6.21), which has many improvements and bugfixes. The SQLCipher code has been cleaned up so that it will compile cleanly under gcc -Wall and VS.NET to enable the use of SQLCipher on Windows. This version also fixes a memory leak that would cause page cache to remain allocated even after the pager was closed. This version should be a drop-in replacement for previous releases, so users are strongly recommend to upgrade.
