sqlcipher3

This library takes pysqlite3 and makes some small modifications so it is suitable for use with sqlcipher (sqlite with encryption).

Additional features:

• User-defined window functions (requires SQLite >= 3.25)
• Flags and VFS an be specified when opening connection
• Incremental BLOB I/O, bpo-24905
• Improved error messages, bpo-16379
• Simplified detection of DML statements via sqlite3_stmt_readonly.
• Sqlite native backup API (also present in standard library 3.7 and newer).

A completely self-contained binary package (wheel) is available for versions 0.4.0 and newer as sqlcipher3-binary. This package contains the latest release of sqlcipher compiled with numerous extensions, and requires no external dependencies.

Building with System SQLCipher

To build sqlcipher3 linked against the system SQLCipher, run:

$ python setup.py build

Building a statically-linked library

To build sqlcipher3 statically-linked against a particular version of SQLCipher, you need to obtain the SQLCipher source code and copy sqlite3.c and sqlite3.h into the source tree.

# Download the latest version of SQLCipher source code and build the source
# amalgamation files (sqlite3.c and sqlite3.h).
$ git clone https://github.com/sqlcipher/sqlcipher
$ cd sqlcipher/
$ ./configure
$ make sqlite3.c

# Copy the sqlcipher amalgamation files into the root of the sqlcipher3
# checkout and run build_static + build:
$ cp sqlcipher/sqlite3.[ch] sqlcipher3/
$ cd sqlcipher3
$ python setup.py build_static build

You now have a statically-linked, completely self-contained sqlcipher3.

Using the binary package

A binary package (wheel) is available for linux with a completely self-contained sqlcipher3, statically-linked against the most recent release of sqlcipher.

$ pip install sqlcipher3-binary
