SQLiteCrypt adds transparent
AES encryption support for popular
SQLite. This small C library
implements a self-contained, embeddable, zero-configuration
encrypted SQL database engine, that allows you to protect your
data in any SQLite database.
-
Embeddable: SQLiteCrypt
links into your application. No need of separate database server
process. A complete database is stored in a single disk file. In
short, this is file-based database engine with AES encryption
support.
-
Zero
Configuration: no setup or administration needed. No Key
Management. Just open database with pass-phrase and use it as
original SQLite database. SQLiteCrypt derives encryption key from user-supplied
pass-phrase that can be up to 128 characters.
-
Easy to use: SQLiteCrypt adds and
changes only one method in SQLite API.
-
Transparent, Storage-level Encryption: SQLiteCrypt encrypts your
data transparently at the storage level -
there is no need to invoke proprietary, nonportable SQL
cryptographic functions to filter your data.
-
Security: SQLiteCrypt uses
advanced AES encryption algorithm to ensure that your data is
safe. AES adopted as an encryption standard by the U.S.
government. As of 2006, AES is one of the most popular algorithms
used in symmetric key cryptography.
-
Performance: AES offer very good
performance compared to other encryption alternatives, e.g. DES.
SQLiteCrypt encrypt/decrypts data as block. It means that
only required piece of data being encrypted or decrypted, not
process whole database every time user executes SQL commands.
-
Changing encryption key on-the-fly:
SQLiteCrypt provide sqlite3_changepassword API function, that allow you to
change pass phrase during SQLite session.
-
Cross-Platform: SQLiteCrypt
is available for Windows, Pocket PC, SmartPhone,
Windows Mobile, Mac OS X
and Linux. Databases are fully cross-platform.
